VEX teams have used rubber bands to help arms lift for years. With the V5 motor properties, we can now measure how much they help.

Did you know that VEX 393 2-Wire Motors are current-limited? And that they can act... unintuitively when that limit is exceeded?

This year's Worlds demo is something practical: a robot that cuts shafts for you!Read More

The Kiwibot is a recently released robot design for VEX IQ. It comes with an autonomous program, but it's written in RobotC. So let's port it to Robot Mesh Python for VEX, and see if we learn anything interesting.Read More

For VEX Robotics World Championship 2015, like last year, Robot Mesh needed some kind of booth demo.

The requirements are open-ended, but challenging. It's got to be made of (mostly) VEX parts, be novel, and be interesting.

We wanted to do something with pneumatics, and something with the Pixy camera, since computer vision is both interesting and interestingly difficult. How about... a robot that plays pong against itself?Read More
