Designing the sensors

Today I did a simple drawing about how the robot would interact with it's environment. I'll probably add some more sensors later, but to get it moving, it only needs two. IR-array to follow the line and an ultrasonic sensor to make sure it doens't kill anyone.

To remove the need of multiple ultrasonic sensors, I'll put one on top of a servo. The servo will do regular panning to make sure the way ahead is clear of obstacles. I need another one on the back if the robot goes on reverse, but right now I try to focus on just going forward.
