Land Walker

The Land Walker is the first 3.4 m bipedal robot. Despite its name, it does not actually walk— instead shuffling on wheels hidden under its "feet" at approximately 1.5 km/h. It was invented by Masaaki Nagumo and created by researchers who hope to someday create similar robots to be used in the military and law enforcement.

Design
The Land Walker stands at about 3.4 m tall, weighing about 1000 kg. It "walks", or shuffles, at a speed of around 1.5 km/h. It has a cockpit, similar to a small airplane, big enough to seat one human. Two cannons are mounted on the arms of the robot, which fire rubber or plastic balls.

Enryu
The Land Walker is very similar to the biped robot Enryu, which was also created by the Sakakibara Kikai Co. in Tmsuk, Japan. The Enryu stands at a height of 3.5 m. It shuffles faster than the Land Walker because it uses caterpillar-like tracks instead of legs. It was built to help in emergency situations, like rushing into a burning building, lifting heavy objects, and rescuing people. Its arms act like human arms, which is different from the Land Walker's arms.
