Quiz V5 - Torque & Manipulators

Manipulators are used to:

• Move the robot from location to location
• Provide feedback to the robot
• Manipulate feedback from the robot
• Interact with the environment around the robot

How many degrees of freedom are represented on the moveable arm part of the robot shown?

• 1

• 2

• 3

• 4

As you increase the degrees of freedom in an arm design, ___________.

• Positioning accuracy typically decreases.
• Computational complexity typically increases.
• Cost decreases.
• Flexibility decreases.

In the image shown (0.5 meters, 3 Newtons), how much torque is required to lift the ball?
