I'm going to talk about

• Why bipedal robots are useful.

Bipedal robots

• Ideal for certain environments.
• Humans feel (more) comfortable interacting with
  human-shaped robots.
• The technology is here!

5
Basic method

• Pre-programmed set of instructions.
• Easier to code.
• Doesn't adapt to environment.

6
ZMP

• Zero Moment Point
• Forces are balanced out.
• Posture is adjusted to achieve this
• Must have stiff joints large feet.

7
Dynamically Balanced

• Example
• Dexter made by Anybots
• Constantly adjusts balance using inner ear like
  humans
• Self learning algorithms.
• Wider range of walking abilities.
• Takes time to learn.

The future

• Walking improves dramatically.
• Robots learn to run
• ...faster than humans?
• Dangerous jobs
• Housekeeper
• Military
