Toy robot kits are also supplied by several companies. They are mostly made of plastics elements like Lego Mindstorms, rero Reconfigurable Robot kit, the Robotis Bioloid, Robobuilder, the ROBO-BOX-3.0 (produced by Inex), and the lesser-known KAI Robot (produced by Kaimax), or aluminium elements like Lynxmotion's Servo Erector Set and the qfix kit. Some robots, such as Ebdot, come ready-assembled.
The kits can consist of: structural elements, mechanical elements, motors (or other actuators), sensors and a controller board to control the inputs and outputs of the robot. In some cases, the kits can be available without electronics as well, to provide the user the opportunity to use his or her own.
