This chapter deals with several projects can be the inspiration of several others of your own creation. The first project is exploring your room.
In this project, the aim of the robot is to move around the room, detecting objects and change it route accordingly. For simplicity of design, and for the robot to turn in place, it is suggested to make the robot from differential drive architecture. If you coose a gear ratio that makes the robot rather sow: 1:9, obtained fro two 1:3 stages. This ensures th at if you make some error in the code and the except everything to go well on the first try but it won't.
The second project is detecting edges. If you're room has a flight of stairs going down, simply equipping the robot with an ultrasonic sensor facing the floor to sense the edge can avoid a bad fall. You could also use a touch sensor instead, connecting the touch to a feeler flush with the ground. When the feeler in front of the robot drops, you have detected an edge.
The third project is following a line. You must follow the edge the tape and te floor, reading an average value between dark and bright so that when you read dark or too bright you know which direction to turn to fnd the route back. You must remove the bumpers and mount a light sensor facing down.
