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!


Fire Force



Recently in Southern California, wildfires have raged constantly, endangering the lives and property of millions of citizens as well as the lives of the brave firefighters on the frontlines battling the infernos. In order to combat the infernos engulfing the state, we were inspired to design and create a firefighting robot to try to save not only millions of dollars, but lives as well. This robot is designed to report and extinguish small fires before they get out of hand. Using advanced 3D modeling technology we designed a part in order to connect our...

Candle Snuffing Robot



We created a snuffer bell part to add to a robotic arm.  The robotic arm will swing down and snuff the candle by starving it of air.  We decided to create this piece because it is a helpful innovation, which frees people of the partially dangerous responsibility of snuffing a candle. Automating the candle snuffer makes it quick and convenient and on top of this, it removes part of the danger of forgetting about a candle and starting a fire.   The new part will be used by those who enjoy lighting candles or the pleasant scent and...

New Half-Circle Gusset


We created this gusset because the gussets provided in the robotics kit are not effective. They are very flimsy and are not stable. For example, one hit from another results in pieces falling off the robot, and sometimes, C channels will get loose, which deteriorates the foundation of our robot. Our gussets have holes at 0 degrees, 30 degrees, 60 degrees, and 90 degrees on both sides with the 90-degree hole being shared. These gussets will be more cost-effective because we won't have to buy different gussets for each angle.

Wire Clip


9210C 2020 CAD Make it Real Challange:


For the 2020 CAD Make it Real challenge, our team chose to make a clip for wire management. Wire management has been a problem for our team so far this season, we have gone through a lot of unnecessary zip ties and have had to spend a lot of time using zip ties to tie down wires, only to have to take them off again when we want to make a change. Our solution to this problem is to make a wire clip that can be bolted onto our robot. This simple yet useful clip will ensure that the wires stay where you want them but at the same...

Axle Support


The idea of the part, known as “Axle Support,” came from a dilemma of team 751A’s competition of the last year. There was a long axle going through the width of their bot that bent under the stress from the weight of the motors and gears attached to it. This 1 inch by 0.5 inch part, composed of a bracket on the back of a metal spacer shaped chamber, is meant to reinforce axles bending or malforming under the pressure of gears and motors attached to it.

The use of this part is simple and effective. The bracket on the back of the metal...

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...

9393B Rockbots Corner Piece


9393B Rockbots Corner Piece

The piece that we created is a type of piece corner piece. However, this corner piece instead of just connecting 2 pieces to make a corner, is just one whole piece. Using this type of piece can save the number of pieces used in a robot and the less pieces there are, the lighter the robot gets making the robot a bit faster.

You might be thinking, what’s saving one piece and a few screws going to do? Well, a single corner piece by itself does not make the robot too much faster, but an entire robot has a lot of...

Roller Support/Shaft Connector Mechanism



We have been working on VEX Robotics for the past three years, and each season, one of the main goals was being able to grasp game objects. Whether you need to stack cubes or launch balls, intake mechanisms have always been a crucial part of VEX robots. From In the Zone, to Tower Takeover, many different intake mechanisms have been used. However, one of the most frequently used structures was ‘Roller Mechanisms’, which are also the main component that form most of this season’s robots. The aim of my design is to improve the stability of the Roller...

Spacer Screws

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...

One-Way Bearing with Conical Rollers


This part was created to help solve the problem of ratcheting systems in Vex. Often vrc competitors are forced to use traditional hardware and rubber bands to create ratchets. While a large amount of these devices are effective, they take up a large amount of space and can cause significant frictional losses. 

    This part is a special type of one-way bearing that was specifically designed to be 3D printed in one part. Typical bearings use spherical rollers which are effective at reducing friction between the outer and inner race. However, spherical rollers...

9393G Gear Problem Solved!


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

  • With this piece I am solving the problem of gear. Sometimes gears take too much space so I created a piece that is like a gear. It works like a gear but it’s smaller and allows the c-channels to move better. It also can be used in replacement of...

Motor Protector


Have you ever wondered if there was an easier way to protect your motors from external collisions and potential damages? Well, with this new gear that we created, there is a lighter and an easier way so that we can protect our motors.

This motor case covers 3 sides of the motor which helps with placing the motor on the robot. Although, you might think that the left outside would be at risk, well there is a removable 4th side to our case which assists you in a way that it is both easy to insert in the case, and it protects the motor just as well as the other 3 sides. This piece of...

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.

Vex Compatible Belt Gears


Our part for the "Make It Real Challenge" is Vex compatible belt gears to combat the inneficancy and pley of traditional sprockets and chains. Our part enable one to use belts for transmission, this could be for a drive or just a more efficiant and accurate replacement of sprokcets and chains. The gears also allow you to use a belt for greater accuracy and precision. 

Introduction: After hours and hours of re-running and editing out autonomous, we could never get a 100% accurate run, and we realized it was because of the massive pley within our...

Team 8054A Cable Organizer Box


CAD Make it Real Challenge Submission for team 8054A


The funny thing about wires is, embarrassingly, how little design thought they are given in VEX robots despite their importance. Speaking from experience, wires are generally added shamefully at the last minute and secured only with zip-ties and a bit of hope. “Bad wires” are a plague not limited to just our team, and our submission has been designed specifically to remedy this issue easily. Our Cable Organizer Box allows us to organize wires in a neat and compact way and takes up minimal space to...

751C - Ball Half Scoop


Ball Scoop - 751C

The Ball Scoop was designed with the purpose of picking up a ball effectively and efficiently. This part is important in the process of holding a ball with the least amount of hardware needed and the best weight efficiency, a lightweight and sturdy piece to ensure that picking up balls can be done consistently. Having this as our means of collection could prove to be very beneficial to the bot. Alternatives in VEX are not round and suited to competitions or challenges involving round objects, for example,...

Make it Real Cad Final Report

We created this part to solve a major issue not only our team had but an issue that many other teams' struggled with. Last year when we were testing and competing with our robot we had a lot of issues with our robot not moving. At first, we thought that our motors were broken and that we needed to buy new ones. But after rigorous testing, we found out the real issue was that the motors were getting dust and other metals in them but that was not the only...

Flex Wheel Inserts


When we first noticed the Flex Wheels were legal for VEX Robotics Competition tournaments at the high school level, we got to experimenting and found numerous flaws, not with the wheel itself but the bores used around the Flex Wheels, and the VersaHex inserts. In addition, we wanted to be able to mount gears and sprockets to the wheel in a more secure manner using screws already on the gears, along with a few other changes. We believe that this part will be able to replace the current bore and insert system and be more compatible with VRC legal parts. The PDF submission and CAD files can...

Improved Rubber Band Intake Roller


Teams in competing in VEX robotics commonly use sprockets as part of a rubber band intake or indexer system for spherical objects. Games such as Change Up are well suited to these designs

We set out to create a dedicated part that offers a number of advantages over the traditional sprocket system:

  • Cleaner, stronger rubber band mounting: The rubber bands fit perfectly into the slots of this part, making them less likely to slip or come off

  • Tough but low profile: The c-channel mounting is stronger...

Autodesk "Make it Real" Challenge- 97101W


After experiencing difficulties with building intakes during the Tower Takeover and Change Up challenges, we decided to make a part that would aid us in assembling a flexible intake system with improved stability. We wanted to incorporate smooth openings and closings for our intake while supporting the weight of the ball in an efficient manner. Thus, our team used Tinkercad version 2019_10_14 to design a new part that would work to eradicate some of these functional issues.

The unit we designed uses a trigger mechanism that functions through the use of potential energy released...

4" Wheel Mounting Attachment


Team 8059X's "Make It Real" Online Challenge Submission: 4" Wheel Mounting Attachment



The 4" Wheel Mounting Attachment is a compact, add-on part to the spokes of 4” wheels, which serves to provide mounting holes for a wider range of constructional versatility. These mounting holes were designed to line up with those on Vex gears and sprockets, but also can be used to connect wheels to one another or mount on any other Vex part easily.

The 4" Wheel Mounting...

Anti-Fog Safety Glasses Attachment


With this year’s challenges to robotics regarding COVID-19, a particular and unexpected problem arose: Wearing a face mask in addition to traditional safety glasses causes fogging on the lenses. This seemingly simple problem can have disastrous results. Through hard work and perseverance, 39Y designed a part that solves this problem. In doing so, we have managed to continue the VEX legacy of providing a fun and safe environment for all students who are passionate about learning, creating, and problem solving.

P-Lock Chain

This is the “P-Lock Chain” which is a modified chain that has more structural strength than a normal chain.  It also has been designed to be more rigid than the high-strength chain so it decreases the chances of the chain breaking when an exterior force or obstruction makes contact with the...

Vex Pulley Block


Team 8059Z's "Make It Real" Online Challenge Submission: Vex Pulley Block



The Pulley Block consists of a bracket that holds the pulley wheels and three mounting holes, of which any two can be screwed into a Vex C Channel. Pulleys increase the pulling force of a winch at the cost of increasing the length of the string connected to the winch. Pulleys have many applications in other machines and we feel as if the Pulley Block can help us bring such applications into Vex.

Compared to...



The part we created was a modified version of a C-Channel, called the E-Channel. We wanted to have the thinnest base possible for the robot as we wanted more space for the internal components.

90 Degree Pillow Block



Structural stability is integral to many everyday structures, such as buildings, bridges, and furniture. And the most structurally stable shape is the triangle. Triangles and trusses are everywhere, think: bridges, freeway signs, and houses. In VRC, advanced teams use triangle bracing quite often, but sometimes, VRC legal parts make it difficult to achieve light, efficient triangle bracing. Our part aims to make triangular structures easier to achieve in VEX.

How to Use

Based off of the structure of a pillow...

Linear Ratchet


VEX U Team QUEEN - Queen's University, Kingston, Ontario, Canada


Linear motion is one of the many things that we feel has been somewhat left behind in the world of VEX Robotics. After our submission of the Low-Friction Slider Truck last year, we felt that we should create another part to add to our linear motion toolbox. An issue with the current linear motion systems is that there is no clear-cut way to ensure one-directional motion, meaning that a mechanism can move in one direction, but not the other. Additionally, many existing solutions...

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...

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...
