Building Fun First Robot


Let’s Begin!

[renkku] from Finland made hist first robot with Picaxe along with Piezo speaker, LED and some other parts. He also managed to hook up a LDR to one of the inputs so the robot knows how bright/dark it is. A LCD display (16*2, serial) has been added, the sensors are a Sharp SRF-005 and ultrasonic detector.

Some Challenges With His First Robot

It has been difficult to teach this robot to navigate effectively. Some methods worked better than others but [renkku] is still not happy with the results. A big problem has been making it understand that he is in a corner.
