|Tankbot is a robot I built from a toy infrared control tank that has two modes:(1)being what the tank already does which is control it with the controler and being able to go forward, backwards, left turn, right turn, and making tank noises which are sounds of a tank either shooting or running(2)the robot being autonomus were the robot runs forward and hits something then it turns.The robot is wired up so you can only use one mode at a time being either the tank on control through its normal on switch or having the normal on switch off and having the collision detection circuit on.The circuit I used was one of Mark Tildens simple sumo robots that just uses two relays, two LEDs, micro switch, and electrolytic capacitor.The circuit has two LEDs that come on when the robot bumps into something.The robot uses skid steering and has two treads.
Problems:I had one problem but I fixed it see the tanks main control circuitry was interfering with the collision detection circuit so I wired the motors going to circuit thru a SPDt switch so that when using the tanks infrared control circuit it would not ground the whole thing out and when I use the collision detection circuit I cut the switch on so the motors are connected and the tanks infrared control circuit off.
This is my 12th robot to build thats not in kit form.
