BabyTigers-98: Osaka Legged Robot Team

The Osaka Legged Robot Team, BabyTigers-98, attended the First Sony Legged Robot Competition and Demonstration which was held at La Cite La Villeta, a science and technology museum in Paris in conjunction with the second Robot Soccer World Cup, RoboCup-98, July, 1998. This article describes our approach to the competition. The main feature of our system is to apply a direct teaching method to b...

BabyTigers-99: Osaka Legged Robot Team

Our interests are learning issues such as action selection, emergence of walking, and self localization without 3D-reconstruction. We implemented teaching, self localization without 3D-reconstruction and embodied trot walking. Our embodied walking showed the fastest movement in the all nine teams. We got second place in the RoboCup Challenge. Although due to the fatal bug revealed in the game, ...

In the RoboCup Legged Robot League field [3], seven colors (aqua-blue, yellow, orange, blue, red, pink, green) are used and robots need to detect and discriminate them. The SONY’s legged robot has the color detection facility in hardware that can handle up to eight colors at frame rate. To detect these colors with this facility, we need to specify each color in terms of subspace in YUV color sp...

Kinematic and Gait Analysis Implementation of an Experimental Radially Symmetric Six-Legged Walking Robot

As a robot could be stable statically standing on three or more legs, a six legged walking robot can be highly flexible in movements and perform different missions without dealing with serious kinematic and dynamic problems. An experimental six legged walking robot with 18 degrees of freedom is studied and built in this paper. The kinematic and gait analysis formulations are demonstrated by an e...
