Robot 1
Here is a very simple robot which I made.
It will move forward until it sees an object. It will stop then look for the clearest path to take. The robot turns towards the clearer path and moves forward. If it is stuck in a corner it will reverse back.
Its a lot of fun.
So it has infrared sensor to detect objects. It also has a servo on which the sensor sits. It has a picaxe controller. This controller is simple to program. Two identical motors turn the wheels and it sits on the battery case which also balances the robot.
It works.
