The RP6V2-C is a kit including the RP6V2 Robotic Vehicle, a NiMH battery charger (RP6V2-CHG), and RC5 remote control (RP6V2-RMT). The battery charger makes it very easy to charge the batteries without having to remove them from the robot.
The RP6V2 is an autonomous robotic vehicle (ARV) designed for fun as well as serious mechatronic experimentation using C-language. Its very comprehensive 138-page manual covers software setup, sample programs, uploading instructions, schematics, and even a C-language primer which can get you on your way to custom writing your own code with the included IDE software package.
With its I2C bus system, the RP6V2 has many possibilities for expansion as your programming skills grow. Use the optional RP6V2-WIFI for more advanced wireless capabilities.
