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!

Zoe Bot


Me and my team are creating a robot that can pick up a box and we decided in unison that it would be easier to design a part for a robot digitally because then we could make and place the measurments  for a new set of wheels that allow the robot to stay stuck in place while peforming the actions it is programmed to do.

Vex edr chain tool


This project is about making a chain tool that can make putting on chain go faster and a lot easier in cramped spaces. This tool will be designed to be easy to use, simple, fast to print, small, and customizable. 

I used Fusion 360 to design this tool and this is my first time using it. I found the program pretty easy to learn but I am still getting the hang of it. My design was very simple but I can see how using Fusion 360 helps alot in 3D design and getting it done fast.

The tool I designed is used to keep the chain tight...

Three-Axis 45* Gusset


Introducing the “Three-Plane 45º Gusset”.  This part has been created to make it possible to simultaneously connect C-Channel in the x-y-z plane in a strong, efficient, secure, and yet simple way. The Three-Plane 45º Gusset can easily be attached to any size piece of c-channel.

In applications where the existing 45º Gusset is used to make an angled connection, the Three-Plane 45º Gusset could be used if there is a need to create additional support or structure in the parallel plane, perpendicular plane - or both planes...

Perpendicular C-Channel Coupler


 The model I have submitted is a perpendicular C-channel coupler. I have been involved in vex robotics for five years now and while designing this C-channel coupler I considered some of the bigger problems I have had when designing and testing robots for the games. One of the more tedious problems is trying to attach these pieces together without adding extra and unneeded metal that negatively affect the robot. This coupler allows teams to connect 2 C-channels perpendicularly, rather than attempting to bind them by laying metal on top of the bars. Since the resulting...

Real CAD: Adjustable Standoff 507C


This adjustable standoff was created on Fusion 360 (version 2.0.6670) because its a part 507C wished they had for their robot. The main function is to be able to have an adjustable spacing whitch is secure. Hope you like this CAD online challenge.

1, 4, 6 and 7 wide C-Channels


It may seem simple at first, and it is. These 4 new c-channels could be used in multiple different building senarios and allow a builder to better construct their robot using these varying width c-channels. Currently there are 2,3 and 5 wide c-channel lengths available. Many robots can be constructed by these peices (cut or not). These new channels would allow builders to explore new pathways to build specialized mechanisms for their robot. Also, builders would not need to improvise with awkward combinations of current channels or create sharp edges by spitting 2, 3 and 5 wide...

The Hook


Make it Real CAD Engineering Design Challenge
2211A KHU Inventors

While practicing for the Tower Takeover game our team was having issues with the rubber bands when the cube holder opened. The rubber bands were breaking, and the cube holder was falling to the front. We modified a flat bar to work as a hook and hold the cube holder.

From this idea I decided to use Fusion 360 to design a custom part named “The Hook”. This new part goes attach to a c-channel with 2 screws and uses a spring or a rubber band. Any of those are...

Hinged Panels


In the attached you will find the design for a 2x2 panel that has provisions that allow them to be used as a hinge.  These can be connected to other panels in order to allow the panel to used by more than just a 90 degree angle.  

By connecting these in groups, strength for the connection is increased.  This is similar to how a piano hinge works.

The holes for the connector pins are serrated in order to provide extra holding power.

To connect the two halves together, a regular metal or plastic shaft (such as used when building with...

Epicyclic Gearing Kit


Why did we choose to design this?

In the Vex Robotics EDR part line, there is a vast array of parts that students can use to learn about the fundamentals of mechanical design. There is however, a gap in the library of competition legal parts that has yet to be filled: Ring gears. We designed our set of 3 ring gears, and accompanying carriers, to fill this gap,and to offer a cornucopia of new possibilities for builders and designers alike. Ring gears are a very important part of the engineering world in epicyclic gear sets, with uses spanning from pencil...

Motor Box with six lockable sides


Motor Box with Six lockable sides

While constructing our robot, we found out that there is only one side of the motor which allow we to lock on the robot. So we decided to create a model with six lockable sides in order to devia the inconvenience. The images and lists below are the applications of our model.

With this Motor Box, people can lock the motor easiler.

Hub Cap


Team 94927G designed a hub cap for VEX IQ using TinkerCAD. The team was losing a lot of rubber shaft collars when they were taking wheels off and this piece helps keep them in place. The hubcap works with regular wheels and omniwheels. It also helps keep the wheel in place with only one rubber shaft collar and helps the wheel be more secure on the shaft.

IQ Shaft Extender


The part we designed is a rectangular box with a square slot through the length of the box that can accept the metal shafts to be connected.  The part has two holes which can accept existing VEX IQ Shaft Collars.  These Shalt Collars will hold the metal shafts in place so they do not pull apart.  The centre of the new part is solid plastic (dense honeycomb pattern) which can transfer the rotation forces (torque) from one shaft to the next.

6083C 3D Piece Entry


Carlos Miranda


Vex IQ Piece Design 2020 Challenge


This piece is a cube that will be able to connect to other pieces from all sides of the cube. It is made up of 6 4x4 plates and 150 connector pins. It can be used to sturdily connect an arm to the front of a drivetrain, or just going crazy connecting arms at all angles with a drivetrain on the bottom. The possibilities are nearly endless. This piece was created with Tinkercad. The piece was made by converting stp files of connecter pins and plates into stl files. Then they were imported...

Corner Beams and/or Plates

We are improving the issue of needing to constantly connect pieces to cover more platforms, make bases, or adding too many pieces to arms and other functions on the robot.


The new piece could be used for a base, as it is sturdier than simply connections of multiple small corner connectors to several beams or plates.It also makes the building process easier, since it reduces the amount of connections made to the robot. Less pieces would be used, so less material would be wasted. It gives more space to connect more pieces to the...

6083A 3D Piece Entry


Identify why you created the part – what functionality are you improving or what issue are you solving?

I decided to create this part to avoid needing to build an arm and/or tower for a robot. This wheel solves the problem of needing to build and extending attachment for a robot. Instead of having an extending attachment for a robot, that could always break or malfunction, this wheel lifts and drops the robot whenever the driver commands.


Explanation of how the new part would be used and how it fits into a complete robot design.

Shaft Extender


    Our custom piece is the shaft extender. We pitched the design because with our robot, the design of our frame requires very precise shaft lengths. But due to limited resources, we usually spend a lot of time looking for the right sized shaft. This part would erase that problem entirely, by allowing us to create our own shafts, at any length.

Snap Together Kit


Have you ever had to take a whole shaft off just to put an additional spacer on? Or to put a gear of another size on? The fact that pieces like spacers, shaft collars, gears, and wheels are enclosed shapes make them frustrating to deal with when building. Well, be frustrated no more! Introducing...the Snap Together Kit, the solution to (most) of your problems!

90 Degree C-Channel Coupler


To help builders when attaching base parts of C-Channel at a 90 degree angle, we often cut a triangular peice of plate. Now, we'd like this peice made for all sizes of C-Channel, so that it can be cut to the correct length.

As part of the robotics team we would love to get pins to decorate our robots in our own customizable way, this would allow us to make each robot different not only in model wise but also a decorative way. 


We first started by measuring one of your vex pieces for size so my piece would end up fitting on the robots. Unfortunately we did not  get the size correct for a while luckily once we did get it we 3d printed it but after that piece broke so we 3d printed it...

Over the past decade, 3D printing has gone from being an exclusive system – limited by patents, prices, and steep learning curves – to being a tool for making and learning – accessible to students, hobbyist, and professional – and quickly advancing due to support from open-source designs, huge online communities, and access to powerful computer aided design (CAD) software such as Autodesk® Inventor™, Autodesk® Fusion 360™, and Tinkercad™. Nevertheless, 3D...

Quick Swap Motor Housing


Quick Swap Motor Housing

By Zac Serocki of Team 8481X



Using Autodesk Fusion 360, I found an innovative design solution for quick swapping motors in the event you need to quickly replace a motor.  During a tournament, if a motor fails and needs to be replaced between matches sometimes the motor mounting screws are not easily accessible and may require removing other components to be removed to access the motor mounting screws.  There may not be enough time...

Currently there are no VEX products that give teams a simple way to lock any fold-out mechanisms. Instead, teams must use bulky multi-part systems, using many rubber bands to retain their parts in place. The SlotLock Variety Pack provides a clean and elegant way for teams to lock their fold-out mechanisms at either a 180, 135, or 90 degree...

Square Standoff Connector


We have a problem that we cannot connect axles to pins or standoffs. We designed our connector to have a circular hole to hold pins and standoffs, but on the other side a square hole for axles. We can put it on our claw to hold our safety bar in place. That is not our main idea, but it would work. We could also use it on our wheels, to add more control to our driving. We used Tinkercad to design our custom part. We had to measure a 1x1 connector pin, which was very hard because of the size of the pin. We also had to measure a standoff connector and a plastic shaft. After we had the...

VEXIQ Hydraulics - Rotary Vane Pump


The goal of this project was to create a part that could create a linear motion, while providing a large amount of stability and force.  I decided to choose this issue because in the past, my team and I have found that creating a lift that requires a linear motion is very challenging. We tried a chain lift, we tried rack and pinion designs, but none seemed to work reliably. I decided that one way to solve this problem might be to use a hydraulics system that used a rotary vane pump.
This part could be used in a variety of robot applications, such as creating a...

Slip Gear


We created our part because in the VEX IQ world there is no way to release the manipulator/lift from the motors to allow it to open/close quickly without taking up valuable button space. Our part could be used to slam down a lift to turn a cube over or to quickly close a manipulator if you want to slowly release a cube or ball. We used Fusion 360 version 2.0.6613 to create our part. At first we were having trouble because we could not load in the VEX IQ gear model. We attempted making our own gear, but could not find accurate measurements of the vex gears. Another...

Plastic Sliding Mechanism
