The Bioloid Comprehensive Kit is the first robot of its kind to be built around smart serially controlled servo technology. This allows the user to construct a wide variety of robot configurations, including the autonomous exploration robot, quadruped puppy robot, hexapod spider robot, dinosaur robot and bi-pedal humanoid...all with one controller board.

The Bioloid kit is made up of many identical injection molded building blocks that the builder can mix and match at their discretion. The CM-5 module, shown below to the left of the three connected servos, is an Atmel ATMega128 based mcu module, which houses both the controller and the Bioloid's rechargeable battery pack (9.6V).

The controller board uses serial connection to communicate with each of the servos, and is used for the Bioloid Beginner, Bioloid Comprehensive and Bioloid Expert Kits
