In addition, since the aim to spread and healthy development of robot technology, technical information will be published as much as possible.
The robots are usually built with RC Servos as actuators and mounted together with sheet metal shapes. The most common frame material is aluminum. However, there have been entries constructed with steel, plastic, and even wood. Different sensors are used by the robot for balance and to perceive its surroundings. A small onboard micro controller or equivalent is used to control the robots movements and if the robot is autonomous it is also programmed to adjust the robots behavior in response to sensor input
ROBO-ONE: The primary ROBO-ONE competitions take place twice a year, with the odd numbered competitions scheduled in the Tokyo area and the even numbered competitions staged in more remote locations to increase visibility and encourage participation in the sport.
