VEX Robotics Engineering CAD Challenge

Professionals and students both use CAD to design everything from mechanical components to complex systems to competition robots. The VEX design system is designed using CAD, and students design their robots using CAD models of VEX parts.

The Improved Integrated Quadrature Encoder

frogs2345

After many issues with the current encoders I have decided to improve them to everyone's benefit. The original Quad-encoders were bulky, but reliable, however often got in the way of some of our designs. The Integrated Motor Encoders were unreliable and difficult to debug. We have decided to redesign the IME to function more like the Quad-Encoder, but have the form factor of an IME. The design is in its simplest form a miniature quad-encoder, but what improves it further is the use of many electronic measures to eliminate the possibility of failing for false values caused by electromagnetic...

High Strength Upgrade

Niamh C

We have redesigned a large portion of the VEX EDR parts library to fit the new high strength shafts. This includes a redesign of the 393 motor to accommodate the shaft, and an alternative modified shaft joiner, making the new high strength shafts compatible with existing 393 motors.

Planetary Transmission

Longarmx

VEX robotics students often find themselves feeling very limited in their robot designs. The Planetary Transmission allows users to easily control the output of two motors without any sliding parts or pneumatics. This design is also very small, allowing students to use that precious space for other mechanisms.

Shaft Adapter

Gkirkman

The newly released vex high strength axle is very good for high torque sutuations. One minor yet extreme flaw is that the high strength axle does not fit into the vex sensors. The reason we require to have a sensor on a high strength axle is that we must record/sense the rotations or angle of the axle. For the 2014-2015 Vex Robotics Game, Skyrise, we designed a scissor lift. Scissor lifts generally have high torque gear ratios therefore requiring strong axles. The high strength axle is perfect for our lift, yet we would like to sense the rotations or angle using either a Optical Shaft...

Patriot Robotics Hinge

tiffong123

Team 1437Z has redesigned the VEX hinge in order to better fit the needs of competition robots. In addition to being more reasonably sized and having a greater range of motion, the hinge is modular and can be put to more use than its original purpose. ​

Wire Gusset

Ian Clavio

Once every other match, either our team or our alliance encountered difficulties with wires becoming unplugged or tangled. Many times those unfortunate problems hindered us from advancing further in the tournament. Through a series of brainstorming sessions, we thought of ways to combat the uncooperative wires and to find an effective solution to replace zip ties. Together, we thought of many ideas including using different localized brains, which would reduce the amount of wires going to the centralized brain. Also, we thought of a way to reduce the possibility of wires becoming unplugged,...
