9.3.2. Inverse Kinematics

Try these first

1. 1.

   What is the primary purpose of inverse kinematics?

   Hint

   Think about how robots position themselves to achieve a task.

2. 2.

   What is a common challenge in inverse kinematics?

   Hint

   Consider scenarios of reaching a point from different angles.

3. 3.

   What is the goal of inverse kinematics?

   • To find the end-effector position
   • To determine joint parameters
   • To optimize motion

   Hint

   Consider what IK does in relation to joint movements.

4. 4.

   Inverse kinematics can have how many solutions?

   • Only one
   • One or many
   • None

   Hint

   Think about different ways to achieve the same position.

5. 5.

   Given a two-joint robotic arm with a total length of 1.5 meters, develop the inverse kinematics equations to determine joint angles for a position at (1, 1).

   Hint

   Consider applying the law of cosines for the given distances.

6. 6.

   How might a robotic surgery implement inverse kinematics? List advantages and challenges.

   Hint

   Think about the importance of precision in surgical tasks.
