This cool project requires no solder – maybe a bit. But it is assembled from many ready parts and kits. It may look a bit expensive but once it’s assembled then real fun starts. So here is what this project needs: a robot platform – DFRobotShop Rover kit; VRbot speech recognitions module, two Xbee modules, Arduino Uno, IO shield, Xbee shield and several smaller parts like adapters and connectors.
Assemble instructions can be found on video above. With sample program you can tell robot move forward, backward, left and right. Once you reach this point you can start improving robot by adding your own commands.
