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!

The hinge will come in two different designs, 90 degree side or a rounded edge. The hinge will be thin enough to be fit in between metal or aluminum bars and will be strong enough to survive the constant and fast movements of the robots motors,...

Improved VEX Universal Joint


Improved VEX Universal Joint

By 8110R "The Knights"

Why it was made:

This part was created with the goal of improving the transfer of axle power up to or beyond the current range of standard VEX universal joints. The regular VEX joints draw the most inspiration from standard universal joints. While this does allow for the transfer of axle power with non-parallel shafts, there is a small range of motion at which this can be accomplished. Anything close to or past 90°...

The Chainhook


Why did we make this?

We designed the Chainhook to attach HS Chain to the robot directly, something that was previously not possible. Originally, someone could not do this, having to resort to only using the part to transport rotational energy across long distances. While that is very useful, we believed that chain could be used for a little more. To attach a chain to a robot directly, the only existing method of doing so was extremely messy and difficult to build. So we designed the Chainhook, elegantly and efficiently allowing chain to directly connect to a...

Quick Release Pneumatic tank holder / Universal...


Quick Release Pneumatic tank holder / Universal easy mount

Software used: Autodesk Inventor Professional 2018, Student

(64-bit Build: 112, Release: 2018 - Thu 02/16/2017)  


Why did we design this part:

After the release of 2018-2019 VRC Game, Turning Point, we utilized 4 inch Omni wheels. These wheels provide great turning ability, however, this caused our robot to easily move horizontally making us susceptible to getting pushed off the platform. We...


The Fs Part.


I'm designing and modeling our f tool that help us to put the f inside the hubs that pushes the hubs from the inside all the way to the scoring zone.

Hinge Bracket


For the Make It Real Challenge 2018, our team wanted a part that would help with our folding claw. It folds down on hinges and rests on two standoffs underneath to maintain the correct height to pick up the caps. This is sometimes inconsistent though as the standoffs may become bent or loose. We also wanted a smaller and more compact way of keeping the hinges at a constant level.

The Hinge Holder is made to be attached to the back of the hinge and can be bolted on. It is flush with the back and the bottom is held up to a certain angle. We made a 90...

Vex Wheel


I designed a new wheel with a skid resistant surface to improve traction and to make wheels used to propel objects more powerful. Our robot this year uses wheels to propel balls at the flags. I thought a wheel with a skid resistant (like fine sandpaper) coating would shoot the balls with more power.


The new skid resistant wheel would be used in the same location as other wheels, just in a way to improve traction. This wheel conatins the same .25 inch hole for the axle as a standard wheel. I also redesigned the interior of the wheel to be solid plastic with no...

Wire Strain Relief with SmartWire Holder


I built a strain relief to fix the wire problems specifically to protect the brain from breaking. This piece would be put right next to the robot brain to hold the download cable in place using friction. It also can fit various sizes of wires including a smartwire for wire management. For example it can prevent the wires from getting in the wheels. Lastly, the strain relief can help keep the robot legal by holding the smart wires back. The strain relief fixes all of the wire issues.

Alignment Bearing


We noticed that the square holes in the VEX EDR pieces allow clearance between it and the screws, allowing the part to move relative to the part it is fixed to. This flaw causes inconsistency. To fix this problem, we designed an alignment bearing to keep the screw in one place.

Bevel GearBox


The part that I designed is an axle transfer gear box. It is a connecting and holding unit for bevel gears so that bevel gears can be better used to change the direction of axles by 90° or use it to split an axle into two going perpendicular to the original spinning direction either the same or opposite of one another, this can be used to reduce the number of motors required to run a subsystem on the robot which is crucial with only eight total motors. To mount the part on a robot you would use 2 ½ inch screws to hold the box together then use stand-offs on the end of the screws...

Wheelie Bar


    As a team we decided to create a wheelie bar to prevent any unwanted tipping or falling over, due to our robots instability.  In our most recent year as Vex Robotics competitors we consistently flipped over in competition which ended up wasting time.  This wheelie bar should help us score as much as possible because we won’t waste time. 

    A wheelie bar has been on our mind since last year when our team encountered this problem.  We have redesigned the wheelie bar so it would be both efficient and effective. ...

The Necessity of a Lift Brace


Hello, my name is Neil Griffin and am part of team 6446C in the middle school division. As part of the VEX Robotics Competition, I saw some teams with unstable lifts that would twist and turn. Since lifts are so high off from the main chassis, teams often have to create overbuilt structures that waste time and space. Angled one - bar mechanisms don't provide much support. Originally, our team had to create a whole back brace system which took up the whole back of the robot which wasted precious resources.

The solution? A dedicated device which has the ability to...

Components that speed up construction


We designed components are specially in order to build convenient, because when building a robot, we need to put every hole alignment of aluminium material, to make the robot's performance is the best, so we have come up with use a widget to make each hole alignment of aluminium material, so that you can need not eyes to alignment, can save a lot of time.

When we designed the parts again, we used Autodesk fusion 360. We designed them in two parts: 1. First of all, the strip is designed to be the same size as the small hole of aluminum material. Secondly, the handle is added...

New type of L piece

VS Puzzler

Dear Judges,

My name is Vineet Saravanan and I am a builder on team 37U, The Narwhal Navy. In our first competition just before the finals our robot broke. The chassis was really weak. We had to franticly rebuild our robot in 5 minutes. Ever since I encountered similar issues with the chassis of our robot and I have always tried to think of a way to avoid this situation and prevent this from happening again. It was...

Ultimate Axle-Plate Interface


This part, formerly known as the "fusion" of the shaft collar, lock bar, and bearing flat, is a combination of the best parts of all three of such components. It is now known as the "Ultimate Axle-Plate Interface". As that is its purpose, to allow axles to connect to plates, with the shape, bulk and grips of a bearing flat, the square central hole from the lock bar, and the ability to apply screws from the shaft collar, this device can replace giant gears with one simple part!

Single Hole Bearing 2.0


VEX components were the reason I stayed in VEX robotics. Albeit, this is my second year, I think that the only reason that I stuck to VEX rather than FIRST was because of the element of creativity needed to utilize the given set of parts. Which is why, when asked the question “What part do you think should be made?” I had a hard time finding a part that fit both the multipurpose aspect as well as the practical aspect. Basically, whether this part would be used, and if used, will it have more than one frequent use to it?

When I looked at the what I though VEX...

Insert Lock


Why the Insert Lock?

This year, we have spent a lot of time working with flywheels. We’ve done our best to minimize our flywheel’s footprint and friction in order to make it best work with the rest of our robot. However, the spacing necessary to fit the required gears was more than we would have liked, so we explored ways to decrease the amount of spacing needed between gears. The insert lock does just that, while tightly holding the gear tight so that there is no slippage between the axle and the gear.

High Strength Set Screw Collar


Throughout the 2018-2019 Turning Point season, our team encountered multiple issues caused by the high strength clamping collars. The steel set screw collar that we designed fits the high strength axle perfectly, prevents slipping, and is reduced in size to fit a regular 2-hole c-channel.

Please check our Final Report PDF document for more information.

44691X Rotating License Plate Mount


The Problem:

When it comes to mounting license plates, there are many options. A majority of teams seem to utilize a fairly common system: screw the blue and red plates together using ¼” standoffs, and attach two 3” standoffs to a metal plate/channel onto which the plates can slide. While this system is relatively quick, simple, and secure, it relies purely upon the outward force the standoffs apply to the plates, which will eventually result in warping of the metal and the standoffs.

An alternative system involves attaching the...

Revised Threaded Coupler


The biggest reason for the creation of this piece was to improve the threaded couplers two simple issues. One being that when screwed together it occasionally nests to far into a standoff and not evenly into the other one, the second issue being that the section where the standoffs meet is a breakpoint. We have witnessed the breakpoint being snapped during a competition. The new part will be treated as a normal coupler in every way, shape and form. The advantage would be that the standoffs would be evenly distributed and protected by the outward shield around them. In Autodesk...

Singular Hole Axle/Screw Joint Insert


Team 2496N CAD Challenge Submission

Singular Hole Axle/Screw Joint Insert


Our team had an issue with bearing flats being three holes long, as we needed a single hole to be one circular without the surrounding holes being affected. 

The singular hole axle/screw joint insert allows for a screw joint or axle to be fit on what is a one hole bearing flat. This singular hole insert is extremely space efficient and can be put into the sides rows on...

Cube Connector


The robot part we created is used for connecting robot pieces and beams together. Our piece is designed to have five peg holes on each side of the cube. It allows connection from all sides. It comes in different sizes but we mostly would use the 1" size. A piece like this is needed because sometimes we had trouble forming 90 degree angles. This problem makes our robot wobbly and not sturdy. We used Autodesk Tinkercad 2018 version. Even though we did not actually print this piece out, we have used Tinkercad in the past to create a robot. We took Tinkercad and 3D printing...

Panel Claw


I decided to build this custom vex claw in order to more easily allow robots to grab the panels associated with the Vex: Turning Point competition. The combined usage of two or more claws would allow the user to generate a simple lightweight claw to lift and flip panels while allowing space for a ball launcher and collection device.

My device has been designed to function in place of the standard green Vex claws and through the use of four simultaneously. This design when used with two claw bases geared together would allow the user to grab the panel...

vex clip on motor


I just want to say best of luck to all and that may the best CADDER WIN!

 I designed a clip on motor so that instead of removing a motor from the robot you can simply just on clip it to do repairs and clip it on the drive

I also 3D print and entered the bonus challenge

Writen Report:

My name is Nathan Mckissick from Gulfport Mississippi, and I designed a part to solve the problem of long motor repair times.  I am improving installation, repairs, and accessibility by making a clip-on motor so that instead of hard-to-get to screws you have...


Helical Gears


January 10, 2019,

Helical Gears 

The parts I have designed and created on Autocad are known as Helical gears which are used in transmissions, high torque operations, and continuous use components. These gears over the general Spur gears are they almost always create contact with another tooth and causes the gear to slip less and support more torque and forces. The gears could be implemented in scissor lifts, Arc lifts, 2-bar lifts, 4-bar lifts, winches, claws, shooters, drivetrains, and so on. The gears would be in a...

VEX IQ CAD Engineering Challenge


My new part is a twelve long by three wide piece that can be part of a claw or used as a wheel guard, it is not a solid piece but rather a one wide making a wide U with a stick coming off of the side. If you put two of these on two different 36 tooth gears facing opposite directions, they can be used for a claw that fits well around the hubs for the 2018-2019 game Next Level. It can also fit around a wheel on the side or the top to cover a wheel so that it does not get stuck on a game/field element during a match. The piece I made can also be used to hold back the wires on a robot, so...
