If you have a sufficient knowledge of C-style programming, love tinkering around with gyros, IR ports, sensors and have a love for robots, then the Bioloid is the robo-buddy you're looking for. It dances, it can sort of flip backwards and knows how to do robo-tuts. We doubt your Robosapien can do any of those.
For budding robot hobbyists, the Bioloid robot kits will cost you — $900 for a comprehensive and $1,200 for a premium kit. Additional modifiers are sold separately.
