I am looking to use the 3pi+ for a robotics class with a software focus. Ideally students would work their way up to a potential fields algorithm using the encoders, gyro, acc and compass for tracking location, angle, maintaining position and advancing towards a goal. Then 1 or more ultrasonic sensors for identifying the obstacles that represent the repulsive forces.
I am curious if I can add ideally an ultrasonic sensor and a servo to the robot ideally without soldering, is it possible for example to reuse the pins on the lcd header for this? Does anyone know of an example online of someone using ultrasonic sensors with the 3pi+? I am not seeing much of anything I believe because the robot is relatively new.
