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.

As a result of this challenge, you may just uncover the path to your destined career! You can sharpen or learn new skills, show off your talent, and build a portfolio that will give you an edge over peers when applying to universities or jobs. This is especially important as employers today are looking to hire new graduates with demonstrated experience and skills.

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™ or Autodesk® Inventor® 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. You can learn more about parametric, direct, and free form modeling on the Autodesk Design Academy web page created just for this challenge.

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!

Nyloc Standoff


This basic part would have the same structural advantages as a regular standoff but with locking end this part could easily be interchangeable with current vex standoffs and would offer a wider veriety of use for this sort of component. This new standoff could come in your same basic lengths including your .5'',1'',1.5'',2'',2.5'',3'',4'',5'', and 6'' measurments. One could also offer a 9" and a 12" standoff in this form for another part for students to utilize. This standoff would be the same width as...

Epicyclic Gear Box Set/Kit For VEX Lifts



Throughout Team 22283A's years in robotics, we always came across the problem where we run out of spaces for gears to make a high torque four bar lift, six bar lift, scissor lift, etc. Because of this problem, we decided to create a gearbox that increases torque by adding more "chains" of the gearbox in front of the next. Our project is a 3D printed epicyclic gear kit/set which incorporates an epicyclic gear box that can be continuously added on to increase the torque of a system;the more epicyclic gear chains added, the greater the torque. Unlike a...

Victor Faillace



Have you ever been in the middle of a competition when your battery slips out from it’s plug into the microcontroller? Or with the purchase of a 250$ robot brain be scared of who holds it so it doesn’t get damaged. This invention is to now both protect accidental drops and prevent from loose battery directly to the micro controller.

The way this case works is with the flexible material it is made out of so the with the same ease of putting a phone case on your phone you will put it into the...

Ball and Socket Latch


The part I created is called a ball and socket latch. I began concepts of this idea in my engineering notebook after struggling for many days on a mechanism to lock our claw inside of the 18x18x18 inch size requirements for robots in the VEX robotics competition. The ball and socket latch is designed so that you can attach each of the two pieces, the ball and the socket, to two separate faces and pop them into each other to hold them together. Under a medium amount of pressure, the two would separate and become independent of one another until they are connected back to each other...

24 tooth gear


The reason why I created this part is so there can be a gear size between a 12 tooth and 36 tooth gear. This season when my team was designing our drive base we wanted to be gear driven so both the motors we had on the drive base would equally distribute there power to both wheels, but we wanted to a little more speed then a 1:1 gear ratio but not quite as much as a 1:3 ratio. We also needed to consider the sizes of the gears so our wheels would be close to where we wanted them. A 24 tooth gear would have given us the exact spacing we would have needed.

The design intent of this...


The amazing castor socket!


As my team started brainstorming robot ideas we realized we needed an omnidirectional wheel. Although Vex already sells omnidirectional wheels their wheels need an axle which can be cumbersome. This castor ball socket will eliminate the need for an axle and will be able to carry out the functions of an omnidirectional wheel.

Snap-On Bearing Blocks


Why was this part created?

Our snap-on bearing block part was created in order to make using axles, motors, and gears more easily.  Bearing blocks commonly lose their screws and become loose constantly, which creates problems during competitions. With this new part, bearing blocks will not have to be periodically tightened and replaced.

How will this part be used?

This part can be used to replace bearing blocks on VEX robots. The snap-on pins can be moved around or taken out of the holes as needed, such as when motors...

High-strength lock bars


High strength lock bars are very useful in keeping gears from breaking in half, and keeping the hub from stripping out. The lock bar that I designed is made so that teams don’t have to us spacers to tighten the bolts without having to worry about bending the bar. Team Virus (3547) makes lock bars from vex one-bar by chopping them into 3, 5, and 7-hole high strength lock bars and sells them to teams all around the country. We have partnered with robosource to be able to sell them in Canada easily.

We make the lock bars by using a broach tool which is a rod that starts round,...


middle hole


A standart 36 tooth gear with a circular middle hole. This middle hole alows us to turn it into a differential or transfer multiple gear lines on one axel, which is also helpful. Lastly, you can use it to design a robot that is like a clawbot but can move it's claw up and down, seperate form the arm and on a motor that is attached to the 12*4 plate on the robot.

Autodesk team challenge Hook


For the benfit of the compitition's challange of high hanging, we decided to design a hook which would complement our design. To hang, we needed to attach something light and simple that would provide enough friction to the pipe. A hook was the right design to complete the challenge. We made it long enough to reach the pipe and added a thredaded hole to extend the hook if needed. As well we chamfered the inside to give the hook a better grip. To attatch the hook me made a square hole with the same dimensions as the standard VEX parts.
