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.

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™ Ultimate or Autodesk® Inventor® Professional 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!

High Strength Clutch

_mark.zachkewich@fmcsd.ab.ca

The part that I created is called the high strength clutch.  I created the high strength clutch for the purpose of protecting the internal motor gears when putting a high strength shaft directly into the motor.  The purpose of the clutch is to permit you to attach a clutch to a high strength shaft.  Also, when you put the axle into the motor directly the force exerted could be too strong, causing breaking or twisting of the shaft or damage to the motor gears.   This is a problem because if it happened during or after every match, the time that it would take...


Make it Real 24 Tooth Gear

2015-2016 Vex Make It Real CAD Engineering Challenge

Introduction

            The purpose of this new product would be to improve upon the limited gear ratios. An example of this is trying to use a 1:28 gear ratio which is common this year. A twenty-four tooth gear would greatly expanded the gear ratio options along with allowing more motor configurations.

Explanation of Part

An example of its usefulness is in shooting designs this year. A lot of teams are...


Omni-Wheel Stop

RUR3

The reason I chose to create this part was to improve the drivetrain of my teams robot. The issue we wanted to solve was the imbalance of different wheel types and the impact it would have on the autonomous period. Specifically our team wishes to use only use VEX 4-inch omni directional wheels to keep the bot as level as possible. The issue is that any other robot could push us in game and the wheel stop was designed to lock the omni rollers of the wheel in place.

A 3D printer will be used to create this part. The wheel lock would then be used on the center wheels of a 6 wheel...


Ratcheting Gear

chengtsew313@gmail.com

For this season’s competitions, flywheels have been rapidly gaining popularity. However, a key issue in a flywheel design is that the high speed requirements of the flywheel means that it is geared to low torque, causing there to be a large strain on the motor when the ball hits the wheel(s) or when the motor suddenly turns off. This can wear out the motors or gears and potentially damage them.

This ratcheting gear can fix this problem. The ratcheting gear will turn with the motor when it is powered in one direction, but freespin when the motor...


High Strength Bearing Blocks

sDiBer

These part was designed to be used in addition to the High Strength Shaft and High Strength Shaft Bearing. The High Strength Pillow bearing is intended to allow low friction axis of rotation off of the surface of Vex Metal. The High Strength Square Bearing Block allows pieces to be locked with the rotation of a high strength axle.

The high strength pillow bearing will allow us to raise up our drive wheels with high strength axels to effectively climb up elevation ramps on other robots.

Motor to stand off screw

kimberleyjake1@gmail.com

This screw will allow the user to connect a stand-off directly to a motor. We found that on a number of occasions, including with our current robot, we needed to attatch a stand off to a motor in order to provide rigidity to our gear box.

Adjustable Angle Piece

MartinFelix

Introduction. 

My name is Martin Felix Gonzalez, i'm student of high school from the CBTis #89, actually i'm in progress to begin the second semester.

I'm working in this project to design a  new piece for a robot, which enables to put two pieces in a specific angle.

His functionality it's to adjust de grades of two pieces.

With this piece we solve the physical problem of get a specific angle between two pieces of the robot.

The Square Kit

hemil-g

Introduction: One of the core principles of engineering execution, especially applied to robotics, is build quality. Many teams plan out their designs thoroughly, and make the optimal use of the design process in order to innovate the best mechanisms to fulfill a certain role. However, all this does not mean much unless the team can actually put the parts together and make it work. The square holes in vex parts makes attachment and reiterative prototyping very easy, but the screws that go in the holes are round, and the diameter is smaller than the width of the square...
