11.13.1. Legged Robot Dynamics

Try these first

1. 1.

   What are the two main phases of walking in legged robots?

   Hint

   Think about when the robot lifts its leg versus when it supports its weight.

2. 2.

   Define Ground Reaction Forces.

   Hint

   These forces help maintain balance.

3. 3.

   What does the Zero Moment Point (ZMP) refer to in legged robots?

   • A point for speed regulation
   • A stability point on the ground
   • A type of control system

   Hint

   Consider stability while the robot is walking.

4. 4.

   True or False: The stance phase occurs when the robot's foot is in the air.

   • True
   • False

   Hint

   Think about the definition of the stance phase.

5. 5.

   Design a control system for a biped robot that needs to navigate through uneven terrain. Discuss the roles of ZMP and GRFs in your system.

   Hint

   Consider the impact of terrain on stability.

6. 6.

   Model the effects of varying ground surfaces on the ZMP position of a quadruped robot and discuss how it could adapt its gait.

   Hint

   Think about how different surfaces would change the robot's movements.
