Touch Sensors
Concept
Touch sensors should act as the last resort on the robot. We would hope to identify obstacles before we have actual collisions but it is very possible for the robot to become stuck on something that could not be detected by the sonar or anticipated in advance. In these instances we need to have some sort of a feedback indicating that we have had a collision so that we can make appropriate corrections. We also need to know when we have actually hit the cone targets and the touch sensors can provide confirmation of this.
