3 cards from this section. Quick, good the night before a test.
What is static friction?
Think about why a heavy box cannot be moved easily.
What does the torque-speed curve represent?
Consider how the performance of an actuator changes with speed.
What type of friction opposes motion while an object is at rest?
Consider the force required to start moving a parked car.
True or False: The Stribeck effect indicates that friction increases at low velocities.
Think about how lubrication affects motion.
A robotic gripper experiences high static friction and is unable to lift a payload. Suggest adjustments to improve its performance.
Think about how friction affects the surfaces that interact.
In a scenario where a robot's actuator delays its response significantly, discuss potential redesigns to mitigate control issues.
Analyze how controller design can optimize performance despite delays.
