VEX Robots
From DEW Robotics
We have built a number of VEX Robots across the years. For specific team robots see the team pages:
VEX Robot Parts
- VEX Controller
- There is a microcontroller
- VEX Programming
- Robots are controlled by programs written in C. There are a number of different compilers that can be used.
- VEX Battery
- The robots are all powered by 7.2 volt battery packs.
Sample Robots
Twitch#VEX Prototype was build during the summer of 2008 as a proof of concept of a four wheel drive base where the wheels turn to change direction. It was based on FRC team 1565's final robot design. It uses a linkage system to turn all four wheels at the same time.
A VEX Linkage robot was built as a proof of concept for heavy lifting arms. The double bar linkage adds lift capability while keeping the item being lifted stable.
VEX Tennis Ball robots were build in 2009 as demonstration robots. The set of five traveled to a number of events to increase interest in robotics.
We built Vexter for the Robo-Hoops event. It was one of our more complicated robots. The zip tie fingers (gray) at the lower front of the robot pull the yellow foam ball into the robot. It travels up the rear of the robot on a tank tread conveyor. It rolls out the top and down through the hoop. The ball drops through a lower guide, gets rolled back into the conveyor and the process starts again.
There is a forward facing sonar sensor to adjust the distance from the wall. There is a light sensor that faces down that is used as a line follower to get the location of the basket. The red tube is actually a light guide to help the side sensor find the start light. Hidden inside is a switch that senses the ball for the next shot.
