Building robots with Raspberry Pi gives you an advantage of getting started faster than any other kits available in the market. Readily available codes and archives of basic robot making are all available online and it looks like the developer just needs to unpack the board and get started. It may sound complicated to build complicated robots with lot of moving arts such as wheels or arms, on the other side its even easier to accomplish that through simple programming which makes controlling and moving parts a pretty seamless task.
