In recent years, due to the vast developments of vision sensors and force sensors, control methods combined with these sensors have been developed, which provide legged robots
with the sensing ability.
By the second method, moving of the legged robot
is performed using the sliders for rotation corresponding each motor marked with a number from 1 to 12.
Another method to move the legged robot
is by using the slider for rotation and two slide bars to control the time (start and stop) correspond to each motor marked with a number from 1 to 12.
Twelve teams from nine countries were selected to participate in the RoboCup-2000 Sony Legged Robot
League: (1) Laboratoire de Robotique de Paris (LRP) (France), (2) University of New South Wales (UNSW) (Australia), (3) Carnegie Mellon University (CMU), (4) Osaka University (Japan), (5) Humboldt University (Germany), (6) University of Tokyo (Japan), (7) University of Pennsylvania, (8) McGill University (Canada), (9) SWEDEN UNITED TEAM (Sweden), (10) MELBOURNE UNITED TEAM (Australia), (11) University of Rome (Italy), and (12) University of Essex (United Kingdom).

In addition to vision problems such as changing lighting conditions and color confusion, legged robots
must cope with "bouncing images" because of successive legs hitting the ground.
Other articles in this issue discuss the champion teams for each league, the legged robot
demonstration, and the RoboCup commentator systems.
The robot soccer player used in RoboCup Legged Robot
Exhibition Match is based on OPEN-R (Fujita and Kageyama 1997), which is proposed by Sony as a standard architecture for robot entertainment systems (Fujita and Kitano 1998).
CMTRIO demonstrated its soccer-playing abilities following its recent win at RoboCup-98's legged robot
soccer competition in which all entrants had exactly the same hardware platform, with team-specific software (for more information about the RoboCup competition, see www.robocup.org/and the article by Veloso et al., also in this issue).
DARPA s Cheetah robot already the fastest legged robot
in history just broke its own land speed record of 18 miles per hour (mph).
- Land Robots (further categorized into Wheeled Robots, Tracked Robots, Legged Robots
, Wearable Robots)
Key players in all terrain robots market are shifting their focus toward legged robots
, which offer ideal terrain adaption coupled with improved efficiency and mobility.
