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!


VEX Suspension System


VEX Suspension System

Have you jared your robot brain, knocked pieces loose, or detroyed your wheels on the PVC pipes during the In the Zone game or climbing the center platform this year?  The VEX Suspension System can solve all these issues..  

We designed a lift system for Vex robots so that the task of reaching elevated objects would no longer be an issue for your robot. We achieved this by creating the Vex Suspension System. It was designed to lift the robot a total 3 inches higher from its standard height. The Vex...

Forty-Five Degree Bracket


One of the issues are team has had in previous years has been lack of support for the tower/arm of the robot. It can be connected to walls on the sides, or brace bars, but it still tilts after so much use. This part will be used to add stronger bracing to all 45 degree angles when needed.

We had all of our members come up with part ideas, and we decided on which one would be the most useful. After several prototypes on TinkerCAD, this is our final design.

This project is very helpful for teaching all team members how to use 3D modeling software and will be useful...

Quadruple Screw Collar


Quadruple Screw Collar

Issues with collars slipping?  Try this,,,

The part created is a square collar that improves upon the design of collars that are used today. With the current collars they have only one point of contact on the axels, with the square design it has 4 possible contact points. Another design change is the actual hole, we have changed it to a square hole so you are guaranteed to get it on the flat surfaces of the axel.

The new collar would be used in the same way that a normal collar would be used, to hold axels...

V5 Smart In-Wheel Motor


AON-Robotics Design Team presents a new V5 Smart In-Wheel Motor concept that enables robotics teams to used the space in theur robot even more efficiently. Particularly useful now that VEX competition rules for VEX-U teams restrict one robot to a cube of fifteen inches and allow certain VEXpro components. Refer to uploaded files for final report. Take a look!

VRC Classroom Battery Charging Station (Single...


Over the past few years, our robotics team has grown to include over 30 students and 5 robot builds. This number of robots requires us to maintain more than a dozen charged batteries for a competition. We’ve tried several different designs for creating battery charging stations, including one made from VEX parts, and another made from an old toolbox. None of those designs worked well for us, so we decided to make our own from scratch. Our prototypes include a battery station for a single battery, as well as for multiple batteries. We got our inspiration from the old battery charging...

Advanced Pulley Motion Kit


Introducing the Advanced Pulley Motion Kit (APMK)

String is often an underused component in VEX robots.

The APMK fixes this problem by introducing new ways to build VEX robots, and to make use of lightweight, low friction, low backlash string mechanisms.

The APMK allows the creation of a very large variety of new mechanisms, as well as offering more efficient ways of creating existing ones.

Software Used: Autodesk Inventor Professional 2019 (Build:136)

Full PDF Report is attatched, alongside...

45 degree new part



My name is Sebastian Alejandro Zertuche Hernandez, I’m 12 years old and I’m driver and designer of the team 10622A – Robotik World Center of middle school category.


I designed this new part because on my robotics school team we was thinking to use a holonomic drive chassis for the robot to be able to move around the field easily using four motors.

But placing the wheels at 45 degrees requires using many parts that take up a lot of space that is useful for...

Universal Vision Sensor Mount


This year, VEX introduced the new V5 control system for the High School Competition. Since the beginning of this season, we have had a great time beta testing the new V5 control system, learning about it’s quirks and abilities every day. One aspect of the new system we were really looking forward to was the vision sensor. Over the summer, we heard numerous rumors about this “camera” and how it could recognize colors. In our heads, we saw endless applications of this new sensor to the VEX ecosystem.


Right off the bat, we...

Ring Gear for High Torque Application


Ring Gear for High Torque Applications

Created by NYIT Robotics


When creating a lift that can raise two arms and a claw capable of rotating, there is a high load placed on the motors. To compensate for the increased load, a planetary gear can be used to provide high torque while maintaining a compact design. The ring gear is crucial to a planetary gear build and provides an efficient path to guide the system on.

Part Application

A ring gear would be mounted...

Team 8440A's Robot!


We created our robot on CAD because we thought it would be more of a challenge that many teams do not do. We really wanted our team to be unique to other teams and stand out to judges at competitions and parents at meetings. We would use this robot in CAD to show off to judges and give an example of how our robot works to others. We used Autodesk Inventor Professional 2018 by constraining, flushing, mating, and connecting different parts and pieces to other parts to clearly create a unique and precise image of our real-life bot! We learned a LOT from this project! We learned patience,...


Mrs. Shelley Crozier


We ran into problems trying to secure the brain without it popping off or even just wiggly. We didn’t know how to properly secure it. When we thought we got it, it kept on falling off. That’s where our part comes in. We call it the Brain Holder!

We kept trying and trying to secure the brain. Nothing ever seemed to work. We also felt that we were using to many parts trying to achieve this. So, we created a part that solves both of those issues. We call it the Brain Holder. It is a part specifically designed for holding the brain properly and...


750C CAD Challenge


A common issue for all VEX robotics team is a lack of stability. With the games getting more and more intricate and complex, many robots have sacrificed stability in order to incorporate all of the aspects of each game. Personally, my team has struggled with securing perpendicular c-channels to each other; often, the c-channels are part of very essential components of the robot so lacking in stability is not an option. The 90 degree standoff will prove to be critical in enhancing structural integrity so teams can continue to tackle the various aspects in each...

4/6/8 bar lock nut bracket


Cad Challenge Report

This part was made to hold an untightened lock nut perfectly in place while keeping its original functionality. In my VRC robot a 4 bar lift is used to pick up the cap pieces and score them as a high cap. Our 4 bar design uses screws and lock nuts to hold the c-channels together, but the lock nuts is slightly loosened from being fully tightened to allow the arm to move. The problem is whenever the arm moves, there's a small amount of friction between the screw, locknut and the c-channel that starts to untighten the lock nut more...

Shaft Insert Strengthner


TEAM 8787A




One recurring problem has haunted our teams building abilities while preparing for VRC competition. The shaft inserts within wheels and geers experience excess strain and torque over time, as a result our wheels have become striped and impossible to reuse. This problem caused shafts to free spin and un-effectively turn the vital components we need. The amount of wheels we've had to scrap due to this...

Team PUPR Cad Challenge Inertia Gear


Inertia Gears – Make It Real Cad Challenge


                Each year, the VEX Challenges get more and more interesting, and its constant game change makes way for thorough thinking and designing. This year’s ball objects must be launched, so being a university team, our restrictions were less of motor quantity and more spatial in many ways. How many motors will it need? How many layers of metal for structure as well as protection once the practical uses are completed. How do we...
