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.

VEX Ball Bearings

thebossbotz

Anyone that is in VRC knows that reducing friction is the key to a competitive robot. When we are at competition we see lifts stained gray around the axles from graphite and robots with complex gearing always tripping breakers because of this evil part of physics; although there is hope! With the power of ball bearings the little bit of extra weight will dramatically combat this well known terror! With the help of Inventor we redesigned the 500 year old design to support a square hole that way vex axles will hold like magic!

Polycarbonate Drive

359A

During the 2014-2015 VEX season, we created a polycarbonate drivetrain. This new innovative design allows us to place holes in various areas enabling the ability to create mechanisms such as; a center drop, a pneumatic transmission (Dog Shifter), a manual transmission , and a four, six, or eight wheel drive. All of these types of drive can fit inside two inches of spacing.

The String Encoder Module

sDiBer

Many teams in the Skyrise Competition require an effective method for measuring the displacement of one or more parts of their robot. Specifically, teams are looking for a method for measuring the height of their lift, or each side of their lift. In competition, it is not an uncommon sight for a scissor lift collapse sideways into a slinky, or to see a Linear Lift jam because the two sides did not travel in unison. The String Encoder solves this problem, by allowing teams to consistently measure how far any part of the robot travels. The string on the sensor is attached to any part of the...

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...

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,...
