Roboticists often use these devices’ namesake theory to express rigid-body motion as rotation about and translation along the same axis. For 10 points each:
[10e] Name these devices that, like bolts, convert rotational motion into linear motion. These fastening devices consist of a cylindrical shaft surrounded by helical threads.
ANSWER: screws
[10m] The Chebyshev–Grübler–Kutzbach formula is used in robotics to compute this quantity, the dimension of a robot’s configuration space. A rigid body in three-dimensional space has a value of six for this quantity.
ANSWER: degrees of freedom [or dof; accept mobility]
[10h] Robotic arms can be managed using this type of control, whose transfer function is a general quadratic all over s. The Ziegler–Nichols method can be used to tune this type of control’s three gain parameters.
ANSWER: PID control [or proportional–integral–derivative control; accept PID controllers or PID control loops]
