Hubo Humanoid Robot

Huo is a biped walking humanoid robot. The inside frame is composed of aluminum alloy and its exterior is composite plastic. A lithium polymer battery located inside of HUBO allows the robot to be run for nearly 90 minutes without an external power source. All electrical and mechanical parts are located in the body, and the operator can access HUBO using wireless communications. HUBO can walk forward, backward, sideways, and it can turn around. Its maximum walking speed is 1.25km/h and it can walk on even ground or on slightly slanted ground.

Overview

The inside frame is composed of aluminum alloy and its exterior is composite plastic. A lithium polymer battery located inside of HUBO allows the robot to be run for nearly 90 minutes without an external power source. All electrical and mechanical parts are located in the body, and the operator can access HUBO using wireless communications. HUBO can walk forward, backward, sideways, and it can turn around. Its maximum walking speed is 1.25km/h and it can walk on even ground or on slightly slanted ground.

HUBO has enough degrees of freedom (DOF) to imitate human motions. In particular, with five independently moving fingers, it can imitate difficult human motions such as sign language for deaf people. Additionally, with its many sensors, HUBO can dance with humans. It has two CCD cameras in its head that approximate human eyes, giving it the ability to recognize human facial expressions and objects. It can also understand human conversation, allowing it to talk with humans.
