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!

Ratcheting Sprocket


My final report is a PDF document. I am not sure it went through, so I will also leave a copy of the report here. This is not my final submission, as my final one is uploaded directly.

I am in the VRC High School Division.


Ratchets are an important part of robotics: they allow you to have multiple mechanisms run by a single motor. This has become increasingly important over the years with a smaller motor limit of eight being implemented. What I set out to do...

Compact Planetary Transmission


The Compact Planetary Transmission (CPT) is an adaptive, variable-ratio gearbox. It takes 2 inputs: One high-strength axle input into the sun gear, and one standard-strength axle input into the reinforced carrier assembly. By varying the relative speeds of these elements, the output gear ratio can be manipulated to allow for optimum drivetrain performance across a wide range of speeds.


The CPT takes one motor in each side (sun and carrier) as an input, and a sprocket (ring gear) as an output. In this configuration, the transmission is capable of improving both...

Variable Angle C-Channel Joint - 8838B

Robohawks- Coach Lund

Created by Derrick Chen from 8838B 

VRC Middle School Division 

Part: Variable Angle C-Channel Joint

Description: This joint allows easy connection of 2 wide C-Channels of any length at angles ranging from 0 to 180 degrees. This would allow beams to be placed at angles other than the standard 90 or 180 degree angle which will open up unlimited possibilities in constructing innovative designs incorporating diagonally placed beams.

Encoder Mount


The optical shaft encoder is one of the most important sensors to include on a vex robot. The sensor measure speed and distance of the shaft by using coding. Many Vex teams use the sensor on their drive train to incorporate rotation and distance into their PID code.

The functionality of the sensor itself is phenomenal, but the casing for the hardware has a complicating design that only includes screw mounts for one side of the encoder. This can cause inconsistencies like friction or uneven elevation of the axel to give inaccurate readings on the encoder. The encoder includes a...

Quick Angle Adjustment

Jelly 2733J

I am Mattias Peroni from team Jelly 2733J, and this is our entry for the 2021 VEX Robotics Competition “Make it Real” CAD Engineering Challenge sponsored by Autodesk. The part we have designed and printed is capable of holding sheet metal and plastics at a desired angle or bend. When building something that needs to hit a target, we look to have precise aim and adjustability with our design. Therefore, it is important to find the right angle of the launching mechanism. This would have been a great piece to have for this year's challenge where balls have to be placed...

Tracking Wheel Brackets


One of the most essential areas to success in VEX Robotics is a strong and consistent autonomous program. However tracking wheels, which are extremely popular mechanisms for autonomous consistency, have a number of design flaws. In this years Autodesk CAD Challenge I designed a custom tracking wheel bracket to eliminate such problems.

See attached final report for further details and video for an overview.

V5 Battery Dock


VRC Team 3018E Paracord - Techna PWN Robotics - Council Bluffs, Iowa, United States.


All VEX robots using the V5 system require a V5 battery. Since batteries have a limited run time, they need to be swapped frequently. Most teams use the V5 battery clips (part 276-6020) to attach the battery to their robot. While these clips do hold the batteries securely, they have several disadvantages. Swapping batteries held on by the clips is generally a slow, two-handed process. The clips offset the battery from the mounting points...

V5 Gearbox Cartridge Adapter



The part we created for the Autodesk Make it Real Challenge is an adapter that allows for use of the V5 Motor Gearbox Inserts on mechanisms external to the motor. This allows for large gear ratios to be created in an extremely small space, enabling lighter and more compact mechanisms, as well as simplifying the process of creating geared mechanisms for new teams.

Design Explanation

The inspiration for our cartridge adapter comes from the VersaPlanetary, available in the VEXPro product line. During past seasons, we...
