VEX Robotics Competition "Make It Real" CAD Engineering Challenge Sponsored by Autodesk®

Have you ever wanted a 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. Note that your 3D printed part from this online challenge may be used in the VEX U competition, but not in VRC.

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!

1:1 Motor Cartridge


We designed the 1:1 motor cartridge for the purpose of simplifying the high-speed mechanisms which often end up being used in VRC robots. New teams tend to struggle when they build their first flywheel and may refrain from ever building a high-speed mechanism again, closing the door for a valuable learning opportunity. The impact of friction, the pain of designing multistage gear trains, and the restriction of parts prevents teams from exploring designs that utilize high speeds in order to be effective. This simple cartridge provides a simple solution to these problems.

The 1:1...

91A 45 Degree C-Channel Coupler

Max Johnson91A

        For the 2020/21 Vex Robotics Competition, my team and I decided to make an X-Holonomic drive train for all of the benefits that come with that design. The issue that most teams come upon is finding the best approach to constructing a holonomic due to the currently available hardware that Vex offers which is primarily limited to the 45-degree gusset. 

        To solve this issue, we designed and printed the 45 Degree C-Channel Coupler. This piece is based on the same design characteristics of the C-Channel Coupler where it will...

Custom Flex Wheel Inserts


After hearing that Flex Wheels would be legal in VRC this year, we were excited to test them on our Change Up intakes. However, after receiving the wheels, we noticed a lot of setbacks, especially with the Versa Hub, which serves as an insert for axles. The main problem is that the large size of the Versa Hub restricts the areas of the wheel that compress, thus massively reducing the wheel’s flexibility. Additionally, the hub has a hexagonal hole, requiring another insert to have an axle-shaped hole, and if a team is using a low-strength axle, which is usually the case, the wheel...

Adjustable Box Claw


Adjustable Box Claw Explanation

We made this part to improve the functionality of a claw bot. We designed this mainly to expand upon the already existing functionality of a traditional claw. Using this part one may be able to have a modular claw that is mainly to be used for box shaped items. The claw can be used to have an adjustable distance, or a preset one for sturdier objects.

              When using this part with a bot, the user may replace the old claw part with the new one,...

"Make It Real" Challenge: C-Channel Angle


The inner side of a C-Channel often doesn't get much use, as parts often don't fit inside of the channel. With the C-Channel Angle, you can now attach other parts 90 degrees from the inner side of the C-Channel. The part also has 5 screw holes on each side of the angle, enabling more freedom for putting in screws. No longer are the days where the inside of the C-Channel receives little to no use.

The Aligner


Imagine it was a match in your regional competition that would make or break your chance to get to World’s. You put your robot on the field only to find that one of the wheels is not turning. Your alliance calls a timeout, and your team scrambles to fix it. Then, you realize that the locking collar fell off and the axle is out of the motor. But every time you slip on the locking collar, it twists and falls off. You finally get it on with seconds to spare, but you don’t have time to tighten the set screw. You run to your match in a panic! Our team faced this situation last...

The Omni-Directional Gear

Tempest 20785D

In most robots I have seen, I have noticed a very heavy reliance on gears. In particular, a reliance on gears for the movement of parts that involve carrying or pushing an external object such as a ball or ring using the robot. I thought it would be more helpful for teams if they had a component that was capable of doing more than what a gear could do with less space and time consumed for many purposes. Hence, I have created the Omni-Directional Gear- a component that can move other VEX parts in a multitude of directions.

The Mountable Wire Clip


The Mountable Wire clip is an incredibly useful part for wire management. The clip can be attached to c-channels, angle bars, and other types of pieces. To insert or remove wires from the clip, simply slip the cable through the slot. While this part was designed for the new VEX Smart Cables, it can also work with the legacy cables.

36637A - Back Lock


The problem began to appear in Tower Takeover 2019/2020 Mission in VEX Robotics Competition. Our robot had a manipulator, which was collecting the cubes from the field. Manipulators mechanism had to be inside the dimensions due to the limitation of robot dimensions at the competition. At the beginning of the match, the manipulator opens until it became in the front of the robot, using  the Rubber bands.

Last Year, while working on the Tower Takeover challenge, we faced a problem in the manipulator mechanism which was responsible for collecting cubes. The manipulator...

5327V's Shaved Bearing


When building a robot, there are many times when a bearing is needed on the inside edge of a channel.  While putting on the bearing you realize you need a shaved bearing.  You can't find a good one, and are forced to make youre own.  While making your shaved bearing, you accidentally cut through one of the holes and have to restart, wasting both a bearing and your time.  If only VEX sold shaved bearings so you wouldn't have to shave them yourself.

Structural Support


Structural Angle Support


My name is Dean Parker, and I have created a Diagonal Angle Support. A frequent problem when building towers or having 90° angles is support. It is nearly impossible to keep something 90° and it to be stable. However, this new piece has solved that problem. This support piece can be used to keep stability in a robot that is dealing with long c-channels being connected together. 

            Before I constructed it in CAD, I began measuring and sketching using a...

Helical Gears for VEX Robotics


For our entry to the VEX Robotics "Make It Real" CAD challenge, we decided to design a set of helical gears that could easily be used in place of the stock VEX spur gears. These gears needed to use the same hub design as the stock gears so that they could fit in the same spaces and be mounted interchangeably. In addition to this they needed to have all the advantages that helical gears bring over spur gearing:

  • Lower backlash
  • Higher maximum loads
  • Smoother operation
  • Less wear

Although helical gears do...
