Sons first attempt at a walking robot

My son needed a skill to do for his Duke of Edinburgh Bronze award. He decided he wanted build a walking robot. This was a big step from the basic electronics he had learned at school. Before attempting this he had played with motors and LED's but he has never done any programming or touched a servo in his life.
Ever enthusiastic he worked out a design he wanted to attempt after looking at some walking robot videos on Youtube. he decided to make a 4 legged robot. here is
the first attempt at testing the basic principles of his design.



as you can see from the video the table is very slippery and he established he needed to add feet to help with the grip. Next step to tidy up the wiring and add feet. progress will be shown in a future video.

Light Following Robot

Here is my light following robot that I built from a kit of parts I bought from maplins. The robot uses a simple circuit using discreet components to make the robot track towards the light.

The circuit uses LDR (light dependant resistors) cells to detect the light source. The left LDR cell controls the right motor and visa versa thereby pushing the robot towards the light source.

This is a basic setup that needs some tuning
