Whether it’s the first or not is up for debate, but it’s a great concept.
Dexter has two legs, stands 5’10” tall, and weighs 135 lbs. Monty has two wheels, two arms, stands 5’7″ tall, and weighs 160 lbs.
The robots have been under development since 2001. Dexter balances dynamically, walks and will be able to run. Monty has one fully articulated hand driven by 18 motors and one gripper. Dexter’s legs and Monty’s arms are driven by compressed air. Driven remotely by a human operator, they can perform a wide range of industrial and household tasks.
Here’s a video of the robots learning to walk, and attempting to be pushed over.
