Re: Ultrasonic sensor for 2015 game
624 used an ultrasonic sensor with great results this year (super cheap HC-SR04s from Amazon). The hard plastic of the totes and cans seemed to work very well with the sensor, and distances were...

Re: Talon SRX and Analog Encoders
In LabVIEW, the Teleop VI runs every time the robot receives a packet from the driver station, so the delay could be pretty irregular.
