2 cards from this section. Quick, good the night before a test.
What is inverse dynamics?
Think of how the robot figures out what it needs to do to move.
Name one application of inverse dynamics.
Consider where precise movements are crucial.
What is the primary focus of inverse dynamics?
Remember that it's about figuring out what inputs create the motion.
True or False: Inverse dynamics is only relevant during the design phase of a robot.
Think about when real-time control might be necessary.
A robotic arm is tasked with moving a heavy object across a table while maintaining delicate control. Identify the factors that inverse dynamics would need to compute and specify how they would adapt if the weight varies.
Think of how weight affects balance and the calculations involved.
Given the mass/inertia matrix M(q) = [2 0; 0 3], the Coriolis matrix C(q, q˙) = [0 0; 0 0], and the gravity vector G(q) = [0; 9.81] for a two-joint robot, derive the torque required if the desired acceleration q¨ is [1; 2].
Keep a careful eye on matrix multiplication and how torques respond to changes in accelerations.
