Bobby: The Robot Friend

Bobby is an old (the reason because it has a stick in his right arm) and smart robot with four engines and two sensors that can play with you and it can be your best friend.

It can move forward, backward and rotate on itself. Into the code, how you can see, there are five functions correlated to the sensors. The colour sensor can recognize four colours: green, yellow, red and blue like the 1x3 technics bricks into the kit, and it can do different thing based on the colour that he recognized.

The other sensor it’s a simple “follow me”, so if you put your hand in front of it, Bobby will move to you.

It’s made using only the parts from the 51515 set.
