Citizen's miniature robot in development The name is Eco-Be!
About Eco-Be!
Eco-Be! Features
It is equipped with a motor unit, based on the miniature step motor used in wrist watches, and is driven by battery. The motor unit is distinguished for its ultrathin size, outstanding reliability and low energy consumption, realized by utilizing Citizen's reputation of top volume in wristwatch metal gear production. Also, high torque level has been realized by high-speed rotation and gear deceleration. With infrared remote control, it is able to move forward and backward and make left and right turns. Each Eco-Be! unit is identified with a unique address in order to make simultaneous movement of multiple Eco-Be! units possible.
