My latest robot, built with an Arduino Nano v3, plugged into a 400pin breadboard. Ultrasonic distance sensor, Sharp IR distance sensor, Laser, PIR motion detector, Piezo speaker, and IR Receiver (accepting commands from a TV remote). Servo to turn the head. Moves around avoiding obstacles, firing laser, beeping, detecting if a human is around, and responding to commands from the remote. Pleased with this, but want to give it more advanced programming. Would like to combine it with a Raspberry Pi ...
