This is the Kumotek VisiON 4G Advanced Humanoid Robot. KumoTek Robotics and Vstone of Japan have teamed-up to offer The VisiON 4G "Advanced Humanoid Robot" to research institutes around the world. The VisiON 4G is undeniably the most advanced bipedal robot of its class, as it has continuously demonstrated superiority by outperforming its rivals at the international RoboCup tournaments in areas such as design, vision, autonomy, and motion simulation. The VisiON 4G body was designed by robotics legend Tomotaka Takahashi of Robo-Garage in Japan and integrated with state of the art hardware and software developed by the prodigy engineers at Ishiguro Labs at Vstone Japan. The VisiON 4G is now available with full English support for international research groups and universities through KumoTek Robotics.

Robots need to share the local information in order to recognize the relation of the partner robots and environment more exactly during the task such as 3-on-3 soccer matches. Therefore, this robot communicates with other robots in network by a wireless function. Moreover, a distributed system enables us to maintain the robot more easily.

The robot has total of 20 DOF. The actuator has a microcontroller and communicates with the host controller though UART multi drop network. Therefore the host controller can receive current angular position of each joint, speed, temperature, and calibrate PID gain and compliance parameters.

Controllers:

The robot has two host controllers and actuator controllers that are loaded in each actuator. One of the host controllers possesses image data from the image sensor and controls autonomous behavior of the robot (Main controller), and the other one computes the motion trajectory and sensor feedback values (Sub controller). Moreover actuator controller computes pid-control and drives the motor.

Sensors:

• Image sensor: captures environment image data around the robot. This sensor is controlled by main controller.
• Acceleration sensor: detects gravity vector when the robot is static. There are two applications with the sensor. One is recognizing whether it is standing or lying down and the robot gets up automatically. And the other is keeping the vertical posture on the level. This sensor is controlled by the sub controller.
• Gyro sensor: detects angular velocity of the robot. The application of the sensor is keeping the posture of the robot on the level when the robot is moving. This sensor is controlled by the sub controller.
• Potentiometer: detects the rotation angle of the actuator. With this sensor, the robot recognizes the current angular position of the joint. This sensor is controlled by the actuator controller.
• Temperature sensor: detects the temperature of the actuator. If the temperature is high, the robot stops the movement and prevents the breakdown of the actuator. This sensor is controlled by the actuator controller.
