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!

Amazing Multitask Piece


Hello my name is Jack Schopp and I am a 5th grader on the Roborunners team 1313A.  I have been in VEX IQ for 3 years now.  I have enjoyed designing, building, and testing my ideas through TinkerCad and SnapCad for the past 2 years. I have been the lead builder on my robotics team for the past 2 years as well.  I have sometimes found it difficult to create a strong vertical support for my robot base.  One that is strong enough to support the robot and any arm attachments to the robot.  I have often thought it would be great if VEX IQ could make a piece that I...

VEX Helical Gears


Helical Gears

By 8110R "The Knights"

Why it was made:

The reasoning behind the creation of these helical gears was the need for easily transferring axle power 90°. While there are some ways of doing this already through either a complex series of gears or a few universal joints, using the helical gears would save a lot of resources and space. A new gear that can cut down greatly on space is extremely useful for vex teams by helping them keep their robot small and also by...

Vex IQ Extraction Driver


Problem Statement

While working with Vex IQ Robots we always struggle with detaching various connectors from the beams. Gears etc. Often time we our hurting our fingers, our thumbs while disconnecting connectors.

We have often also found ourselves in a situation where we are not able to eject/detach the battery from the brain.

We have a Vex IQ battery back, which uses AA battery, and often the back lid is stuck, and it’s a pain to get the back lid, and then the batteries from the VEX IQ battery pack.

Following are main...

Axle-Screw Adapter


Axle-Screw Adapter


When building our lift, my team found that we had two options for joints: axles and screws. We found that there is no way to transition between axles and screws, which would have been very helpful for creating new joints. Also, there was no way to attach parts directly to the end of an axle without a large apparatus. We have always needed to resort to large mechanisms using gears and metal to attach parts to axles. Lastly, screw joints could not be attached to a motor, potentiometer, or optical shaft...

The VEX One-hole Wide C-channel


Have you ever had trouble with the design of your lift or base? Is it too bulky, heavy, and space-wasting? My team has seen many robots struggle with a lift or base that weighs too much, including us.

The one-hole c-channel is a revolutionary piece that is slimmer and lighter than a conventional two-hole c-channel. It can be utilized in creating more effective bases, lifts, and intake systems.


Please look below to see more information in our final diagram, report, and pictures.

Chain Tensioner


Throughout many designs for VRC competitions I have consistently run into the problem of having too much or too little amount of tension in chain. Whether it’s chaining the drive together, powering a flywheel, or using a conveyer belt style intake, getting the right amount of tension in the chain drastically changes the quality of the design. To solve this tension problem, I’ve designed an adjustable roller bracket that will change the tension with more precision than simply changing the number of chain...


Pneumatic System Mounting


Pneumatic system mounting brackets for Vex Robotics

Software used: Fusion 360 Ultimate, Student (version 2.0.3800)


Why did we design this part:

When the 2017-2018 Vex Robotics game In The Zone was released we felt that pneumatics would be an important role in our robots design. We spent months developing different intakes for various game elements using pneumatics and we quickly realized that there isn’t a great solution for attaching various pneumatic components to a robot;...

VEX Part: Caster


There have been times with our robots where we have needed to have a component "hover" at a particular height while driving over the mats.  We tried using standoffs but found they created too much drag while moving forward or pivoting.  We tried using wheels from the tank tread kit which worked when driving forward and backward, but they created the same drag when turning or pivoting.  We had to overcome the issues we faced by doing our best to stabilize the hovering component to reduce any bounce created while competing.

While working in our robot lab...

Make it Real CAD Engineering Challenge Entry


The Vex IQ piece we decided to make for this challenge functions as a corner connector. We thought that this design could function and should function as a Vex IQ standard product, as it can be used effectively in many situations. This piece is great at stabilization on chassis, arms, intakes, and anything else. We found that this piece comes in handy the most when functioning as an arm connector. So therefore, this piece is a great stabilizer and is very versatile.   The piece that we printed was used to securely hold beams and stabilize a mock arm base. To make this piece, we...

Continuously Variable Transmission


A Continuously Variable Transmission, or CVT, is a transmission that can seamlessly change to any ratio within a continuous range of gear ratios. This design is based off the variable diameter pulley, which is composed of two pulley sheaves that move toward and away from each other. Two sets of these pulleys form the input and output shafts, with a flexible belt transmitting power between them. The pulley sheaves are moved with "push plates", which themselves are moved by turning VEX worm screws.

Motor Controller Holder



The Six Slot Motor Controller Holder was designed with the intention of improving wire management on VEX robots. Too often you see teams with motor controllers and wires hanging from robots or tied into a bunch making it difficult to work with and risking damage to the motor controller.

How the part would be used

The Motor Controller Holder can be used by snapping six motor controllers into the slots. Movement of the motor controllers would be prevented by the retaining walls on the sides, the angled portion of...

Motor Controller Clip


Two of the most important parts of the bot would have to be the wires and the motors. Without these components, the bot could not possibly run, so it makes sense that maintaining an organized wiring system is one of our top priorities. As compared to other levels, high school VEX robots are easily distinguishable due to their messy wire management. As our teacher puts it, “the way you can identify a high school robot is through the messy wiring throughout the robot.” As a team, we wanted to break this stigma because there are multiple uses for maintaining neat wire management:...

Make it Real CAD Challenge by team 1550C Da...


Da Swedish Fish, team 1550C, consists of Mattias & Cecilia Peroni. Our entry is a piece that is designed to hold somthing on in two different 90 degree directions from the pull on it. Like attaching a claw to a lifting mechanism, and securely keeping it on while driving away from the pole. The piece can also be used to hold a platform and a sensor.  Full description and pictures in the PDF file.

Direction Dependent Gear Selector


To address complicated mechanisms for supplying more torque in one direction and more speed in the other (e.g. catapults with their wind-down and release), AURA created Direction Dependent Gear Selectors. These are an elegant solution that can be implemented directly to a simple gear train to power such mechanisms, with no extra external control needed - all switching is done purely based on the direction!

See the attached report for full details.

Chain Adapter Kit


Ever needed to combine the functionality of a chain and the VEX structural system? Through CAD, it's now possible. 

Team 99484A presents the Chain Adapter Kit: a set of 4 types of custom chain links to combine the uses of chain and structure to increase the utility of your subsystems. Use it to connect chain to standoffs to create an tension-adjustable and durable chainbar linkage, or link it directly to a VEX C-Channel to move a system. Expand from the traditional use of chain and sprocket: manipulate the kit to create innovative designs.

Pneumatic Tank Supports


Actuators are a critical part of any robotic design. In the VEX Robotics kits, two types of actuators are motors and pneumatics. Motors are used in nearly every mechanism, and there are different methods and structures for effectively securing them. Pneumatic systems are just as powerful, but there are few methods for effectively securing and mounting pneumatic tanks - arguably the most important component of a pneumatic system. Common methods of securing pneumatic tanks include rubber bands, large zip ties, string, and a standoff or metal cages; the first options are prone to breaking...

Curved Linear Track


This piece is designed to change the direction of linears. I designed this piece because when I was challeneged to make a claw trash truck, I couldn't because there was no curved linear track. This piece gives more functionality to linear lifts. This would be used with linear tracks to change the direction of the linear slides. Using TinkerCad 123D, autodesk free online app, I took a circle and manipulated it with lots of hole pieces. 

I learned that creating a detailed piece is challenging, I will probably use 3D designing in the future for future robot drawings. 3D...
