Book 15, Question 57
Why Is Balancing on Two Legs Such a Challenge for a Robot?
Balancing on two legs is hard because the robot's weight must stay over a tiny spot! That spot is where its feet touch the ground. If the weight drifts outside it, the robot tips over.
More fun facts
- Many humanoid robots walk with slow, careful, flat-footed steps to stay balanced.
- Scientists studied bird legs, including ostriches, to build a two-legged robot called BirdBot.
- BirdBot uses a spring-loaded system that quickly switches its legs between straight and bent.
- Two-legged robots might one day explore dense forests where wheeled robots can't go.
- A walking expert says people think walking must be easy because babies do it, but it isn't.
