Make It Real CAD Engineering Challenge Sponsored by Autodesk ®

Have you ever wanted a particular component for your robot that was not included in the kit of parts? Do you want to design and make something unique that sets you apart from your peers? Then the “Make It Real CAD Engineering Challenge” is for you! Autodesk is sponsoring this challenge and giving you a chance to focus your passion for CAD and apply your skills to solve a real world design issue.

In this challenge, you will use the same Autodesk 3D design software used by professionals to conceptualize and model a new part for a robot that improves its functionality or overcomes an existing problem. The new part must be designed to fit an existing robot, and may consist of multiple pieces that form one part design. The robot may be a competition robot (VEX, FIRST, BEST, PLTW, SkillsUSA, TSA, etc.) or another robot that performs an interesting task. To make it even more exciting, you will also have the option to compete for a “bonus prize” by 3D printing your custom part! Note that your 3D printed part from this online challenge may be used in the VEX U competition, but not in VRC or VIQC.

To help you succeed, access to Autodesk software is available at no charge to students. In the Make It Real CAD Engineering Challenge, you must use either Autodesk® Fusion 360™, Autodesk® Inventor®, or Tinkercad™ to model your custom robot part. Whether you’ve used the software before or are brand new to CAD, the Autodesk Design Academy provides lessons and video tutorials for all skill levels.

To get started, carefully read the complete challenge requirements on this page. Then visit the Autodesk Design Academy challenge page to download software, watch tutorials and learn how to create custom parts. When you’re ready, return to this page to submit your entry.

The future is yours to design, and we can’t wait to see how you change the world!


Caster Wheel for VEX IQ


//---------------Brief Introduction---------------

Team 1313A - RoboRunners (Elementary VEX IQ)

In many beginning level VEX IQ workshops and classes, we have helped kids build their first robot. An easy beginning design is the VEX IQ Speed-Bot. We made this part because when kids drive a VEX IQ Speed-Bot on carpet, or play this year’s “Next Level” IQ game, the “standoff and connector” that sticks down gets stuck on carpet or blue barriers and drives jerky. This is a problem if you want to use the Speed-bot on anything other...

Multi-Directional Collar



TEAM 7870 E


As any robotics participate can attest to, the shaft collar is one of the most challenging parts to work with. Reasons vary from the fact that the set screws are often lost or broken to the fact that collars tend to fall off easily during a competition. For this reason, our team designed a new shaft collar, based off the original, in order to optimize its use in the everyday robotics and to fix the issues mentioned previously. 

Our new part would end up fixing all these...

Multi Purpose Wheel Design


First of all special thanks to my brother  to design support and hardware for this challenge.

Why this Design?
    I found an alignment error in  recent robots in university challenges.
after some mechanical research I found that the accuracy comes with higher accurate manufacturing.
    Presently, in VEX ROBOTICS normaly weight of robots is between 5 to 35 kgs.

  1.  Why you created the part?

    Because , i found an alignment error in...

Wheel Stopper


This mechanism stops the wheel from turning. It'll be useful when fighting over the top platform in Turning Point because it causes resistance. The mechanism is basically a worm gear connected to a motor that can extend out to go in  between the rim of the wheel and stop it from moving.

Cable Anchor


In late summer of 2018, I began my first iteration robot for the VEX IQ Next Level Challenge. I made a list of parts that I needed. I thought that I remembered seeing a cable anchor for VEX IQ, but I couldn’t find it on the VEX IQ website. When my mom called to place the order, we asked VEX Support if there was such a part, and they said there was a cable anchor for EDR, but not IQ.

As my team worked through the iterations of our robot, the cables were a constant problem. The robot’s arm needed to be long in order to pick up the bonus hubs from the pegs. We needed to...

C channel sliders


The C channel sliders I have design are intended to adapt 2, 3, and 5 hole wide C channels into use as a rail for linear motion, like the current linear motion kit. I created this part as an alternative to the current linear motion kit, because I have found last year that there were many issues with friction between the track and truck, limited structural support, and other issues which caused my team's scissor lift robot to fail. This year, my team has been using the linear motion kit with ball punchers, and also has started on prototyping improved linear systems using spacers to...

V5 Mounting System


V5 Mounting System

CAD and Report by Devin Ho

3D Printing and .stl Conversions by Alan Onuma


The V5 Mounting System is an extension of the existing parts used to mount V5 Electronics. There is no way to mount the V5 Brain, Battery, Vision Sensor, and Radio in ways other than what the flanges, battery clip, or existing screw inserts allow. This means that teams must use bulky and inconvenient metal structures to mount these parts in different orientations. These parts allow teams to mount their V5...

Vex Snap-In License Plate Holder



This license plate holder was created to allow you to quickly remove and replace VEX license plates, while also providing a slim and spatially conservative holder. By providing small ridges in the sides of the holder, it allows you to snap the license plate into place much more quickly than screwing or rubber banding it onto the robot, and hold it so it will not fall out like it would if you had hung the plate over a piece of metal.

On the Robot

This part is used in a VEX robot to hold license plates in a convenient...

Licence Plate Holder


The License plate holder allows teams to store and display the license plates during a match. It also alows teams to quickly switch the plates after the match.

Vex IQ ball bearing holder


I created a Vex IQ Ball bearing holder to allow robots to have faster more precise turns. Since Vex IQ robots turn a lot during their runs this will allow them to accomplish tasks much quicker, and more accurately. The bearing and holder act in place of a robot's two back wheels and has 2 holes at the top where it attaches to the robot by axles. I first drew a diagram of how I believed it should look. I then designed it using Tinkercad version 4.4. I designed it by merging a sphere with a rectangle then using a hole that is the right size to fit a 2 cm diameter ball bearing...

VEX Linear Actuator


VEX Linear Actuator


The VEX Linear Actuator converts rotational motion into linear motion. The linear actuator is designed to substitute the pneumatic system. With the linear actuator, only one motor is required to create linear motion as opposed to the two motors lost with use of pneumatics in the VEX competition rules. The design of the linear actuator is focused on compactness, which results in the VEX V5 motor being placed beside the linear motion...

Brain Connector


On our robotics team we have building rules when we build robots. One rule is that we use standoffs to connect the brain to the robot. The standoffs also help keep the wires organized.  HOwever, when we put the standoffs in the brain and then have to take off the brain or change wires the standoffs are hard to get back into the brain.  So we designed a piece that has standoffs  connected to the beam.  The standoffs are in the middle of the beam so that the top and bottom of the beam can be used to conenect the brain in a vairety of ways to the robot.

Tactical Track



Do you have trouble disassembling parts repeatedly while building a robot? Have you ever struggled to move numerous screws in order to adjust the position of a structure by just a unit? We had been meeting with such problems frequently while building robots and sometimes  having to re-install some of the most complex structures on the chassis over and over again, which is the reason why we designed this ‘Tactical Track’, that will help you move the parts on the chassis quickly. The structure we designed is quite similar to...

V5 Motor Holder



The purpose of this design is to better fix the V5 motors. According to the design of the vehicle, the motors are often installed where there lacks fixed surfaces. The motor frame we designed can be installed on the outside of the motor, and the frame itself has a number of holes that can be used to connect it with the main structure of the robots, so it could provide enough fixing points for a motor when the motor itself cannot be fixed due to the structure.

The inner wall of the motor frame fits the appearance of...

Universal Ratchet and Pawl Mechanism


Why did we design this part:

In the 2018-2019 vex game Turning Point, an extremely important task that the robot has to be capable of accomplishing is to shoot balls at the flags. We knew that a ratchet and pawl system would be extremely beneficial for a very common shooting mechanism, the flywheel. We realized that with currently available vex parts, we could only implement this system with an 84 tooth free spinning gear along with some other unconventional parts. Therefore, we decided to develop a more simple and universal ratchet and pawl system that could...

Single hole fixed column


Single hole fixed column


In the construction of the robot, we used the rubber band to assist the mechanical structure and the motor to carry out the lifting action many times. However, when the rubber band is fixed, we often encounter the problem of how to fix the rubber band. Now it is fixed by the structure of the long screw or nut column (Fig. 1).


Fig. 1

When the rubber band is encountered, the screw thread and the nut column edge rub, causing the loss of the rubber band, reducing...

Pneumatic Twin Bar Suspension Kit


    The pneumatic twin bar suspension kit was created to provide improved flexibility and torque to the robot chassis. This part will allow for a greater range of configurations with robot design. Most chassis systems generally have a fixed drivetrain unit and none of the shafts shift to different positions. Currently, robot designs are constrained by the fact that any form of a moveable drivetrain unit requires a significant amount of resources and space. This pneumatic twin bar suspension kit addresses these constraints without compromising overall mobility.


Beginning Design


Beginning stages of the design. The robot was not yet decided/built. Khlover started the CAD project in September to learn the program and start a basic robot base. She used Inventor 2016 Professional for her project. Our first tournament was on November 17th and the robot was running on the Legacy system. After that tournament, we received the V5 system. We decided to change the robot design completely to be more efficient with the new system. Before the new design was completely built, Khlover was unable to finish the project due to health reasons.

License Plate Holder


This license plate holder is designed to make dealing with license plates the easiest part of VEX robotics. The holder can secure a blue and red license plate simultaneously. It allows for each plate to be swapped from one color to another with ease by having both plates rest inside of the holder’s slot. Changing the color of the plates is as simple as sliding both plates out of the holder, facing the color desired toward the open face of the holder, and placing the plates back into the slot. When it comes to mounting the holder, teams get two options. Teams could...

Team Lunatechs 3D Tire


Team Lunatechs 3D Tire

Intro: We created this part because we thought that traction might be a problem in the arena. Also, we thought that climbing up the platforms was going to be a big problem. The tire on the left is made to increase traction on the foam ground of the arena. It was also made to make climbing up the platforms easier. Description: This new part would be another wheel on the robot, it will provide enough traction to move around the field without worry. It will stop other robots from pushing it off any of the platforms. Also, it will allow you to get your robot to...

Prestige Worldwide Battery Holder


With this new part we will be able to change out our batteries much easier than with the vex battery clips. We always struggle to change out our batteries because we had to place it in a tight space because of our robots design. This design includes a cover that will allow he more narrow part of the battery to fit under in order for it to be secured and a lip around the edge that it shallow enough that the battery can be placed flat on it and be plugged in. This increased my knowledge in how to use Autodesk Inventor which will help me design products in my future career as a petroleum...

39k's Adjustable Gear


We created this part out of necessity. A big part of this competition is shooting balls, and most common shooters require a gear that is missing teeth. Teams, us included, had to cut gear to achieve this. With our design, you can slot teeth in and out of the gear, making the gear versatile. This allows teams to be able to do a range of things, from leaving gaps in the gear (like we needed this year) to being able to change gear ratios on the fly. 

We created this project by using Inventor 2016 Professional 64-bit edition, build 138. For dimensions of the gear, we measured a...

Chassis stabilizer for VEX IQ


Hi, my name is Naomi.  I am in 4th grade and this is my first year in VEX IQ. My favorite color is Blue.  I like to read and I like driving and coding.  I am part of 21117A’s team.

I made this part to balance the back or arms on the front.  It will not fall backwards with arms lifted high.  It can also be used on the front if the robot wants to fall forward.  My first drawing had a wheel, but that would not let robot turn so it was changed to a ball.

My coach and I both learned how to use Fusion 360...

Two-piece shaft collar


This is the two-piece shaft collar. For this we only had to design one half, as the two are identical pieces. When rotated 180 degrees, one component slots into another. This is an adaptation of the typical VEX IQ shaft collar, but it has a square whole in the middle to tightly fit onto axles. It can also be assembled anywhere on the axle, rather than only being able to slide the shaft collar on from the end of an axle. The two-piece is able to move horizontally, allowing the user to easily separate the two pieces and remove from the axle, but cannot move in any other direction,...

V5 Scuff Controller Add-on


Jasper Kosa

MCC Robotics


The Goal:

The motivation to create this part was simple, to increase the number of buttons accessible on the V5 controller while simultaneously maintaining control of the joysticks. By default, there are only 4 buttons that can be pressed with the user's index fingers on the front face of the controller. I have always disliked the lack of rear buttons on most controllers, why would you not want more inputs accessible at any time? So to...

Right Angle connector


A Micro USB port is fragile and can only be plugged in one way. In an effort to make these ports more functional the Firestone engineering club bought adapters from Micro USB to USB Type-C. USB Type-C is a more robust connector that can be plugged in right side up and upside down. However these were long and our cable does not fit imbetween the adapter and our linear punch. To solve this I thought of a USB Type-C connector that is a right angle and goes up towards the screen. This would allow our team to use the USB Type-C connector without issues of compatability with the adapters...

4073 G Make it Real


My idea is to combine a screw and a standoff. It also functions similarly to a nut. This will lessen the clutter in the toolbox.  With less in each toolbox, everything will be more organized. One can use a nut and a smaller screw to create a standoff. If you just use the smaller screw, the screw insert functions similarly to a nut. If you just use the nut, it is a screw. The screw insert will have many sizes, so space isn’t a problem.With multiple sizes and easy use, this will be something every VEX team wants.   I used Autodesk Inventor to create this part....

Vex Ball Bearing with High Strength Axle...



The part I created was a ball bearing to high strength axle adapter to decrease the amount of friction on subsystems and allow for more precise subsystems on robots. This idea came to me because I noticed that in shooting games, such as the current one, a common design teams resort to is a flywheel. A flywheel is a wheel (or multiple) spinning at a very high RPM to accelerate the ball and ‘launch’ it. To optimize flywheels the goal is to create a system that is as frictionless as possible especially on the higher RPM stages which was my goal to make easier. A...

V5 Vision Sensor Protective Lens


V5 Vision Sensor Protective Lens

As many VEX Students, Teachers, Clubs, and Organizations are moving into V5 and are now trying out and learning from the new sensors V5 offers, there has been a great deal of money spent to enforce such changes. Because switching to a new system is expensive, as well as trying out new products can be pricy too, it would be best suitable to take care of the V5 system as much as possible. But despite taking care of such an expensive system, we cannot be cleansed by the fact that we all make mistakes, and that simple mistake could cost a great deal...

Motor Box


We created a part because we need it to solve motor problems on our robot. Our part will be helpful in the design process of our robot.

Our part would help the problem with rattling motors and would keep them in place. Part of the new piece will connect to the part the motor is usually connected to and the other will keep the motor in place.

We used Tinkercad 4.4 because our team is most familiar with this software. We designed how we think the part will look like. We weren’t able to 3D print our...

Gear Box


This gearbox is designed so it will be easier to switch gear ratios.  Previously on our robot, we have had to remove several axles to change out gear ratios.  This was a long process and often involved hammering out warped axles. This process could be made simpler and safer with replaceable gearboxes.

Autodesk Inventor version 2019 was used to create the shell that the gear chain will be housed in.  It was also designed to fit within premeasured size dimensions. This will allow the gearbox to be screwed on to the robot wherever the gears...

Standoff Linking Screw


           This design, created in Autodesk Inventor, provides the capabilities of a double-sided screw without the risks its shape presents. The two ends of a headless screw allow for the linkage of two standoffs. However, one problem which has occured in my experience with the part is the tendency for the screws to get lodged inside the holes of the standoff, which makes their removal difficult. With this modified double-ended screw, the removal and insertion of the double-ended screw is facilitated by the hexagon-shaped extrusion, which matches the...

Description for MIST 7035T Make It Real CAD Engineering Design Challenge:

     This submission for the Make It Real CAD Engineering Challenge is presented by the Miraleste Robotics team, 7035T. For the challenge, we are designing a pneumatic mounting system since there are not any official VEX parts for mounting the system. This will include a hexagonal nut, which is used in tandem with a 6-32 size head motor screw and clip, which is plastic based and designed to restrain motion. Specifically, they are...

The GalenVEX Slider


We are Galen VEX IQ 2 (48327W), and we are going to VEX Worlds 2019 after winning the Excellence Award, Skills Challenge and runners up.

Why did we design this part? “The Galen VEX Slider”

We created this simple piece for our robot because we realised that our arm was very flimsy. We thought about how when the arm moves, we want the piece to move as well, so we took out a line on the piece so the pins can slide along it as the arm moves.

The new piece will be used to make the robot more stable. It is to be used for the claw or moving parts that are...

7035M Adjustable C-Channel Make It Real CAD...


Our team, 7035M from Miraleste Intermediate School, has created the VEX Adjustable C-Channel using AutoDesk Fusion 360 version 2.0.5331. Our invention will help eliminate cutting of C-Channels when building the robots. This will result in saving time, saving money, and most importantly saving the environment.

Double Corner Connector


We created the part because our corner pieces kept falling out and the alternatives like connecting two of them would not work because getting a secure connection between the pieces and still being able to attach other pieces to the corner piece was not really possible. The piece can be used to attach pieces in a corner position like normal but it has a much stronger connection and can be attached to from both sides while maintaining the stability of attaching directly to the robot. I used fusion 360 version 2.0.3797 to alter two corner pieces and extend the walls of one of the...

Friction locking axle collar


Aloha judges, 

The part i have created is a friction locking hinged axle collar, which i have been drawing for multiple months and have worked with many of my engineering and drafting teacher at my school to make it as effect and simplistic as possible.

I Created the Clamping axle collar to address the problems with the current axle collar, where the screws strip often inside of it and they are also a pain to put on and manage. The clamping axel collar is able to but plan upon the axle with ease and the 2mm cubes on the sides allow for a 64 screwdriver to be use as...
