coriolis
Purpose
Compute the manipulator Coriolis/centripetal torque components
Synopsis
tau c = coriolis(robot, q, qd)
Description
coriolis
returns the joint torques due to rigid-body Coriolis and centripetal effects for the
specified joint state
q
and velocity
qd
.
robot
is a robot object that describes the manipulator
dynamics and kinematics.
If
q
and
qd
are row vectors,
tau c
is a row vector of joint torques. If
q
and
qd
are matrices,
each row is interpreted as a joint state vector, and
tau c
is a matrix each row being the
corresponding joint torques.
Algorithm
Evaluated from the equations of motion, using
rne
, with joint acceleration and gravitational
acceleration set to zero,
= C(q, q) q
Joint friction is ignored in this calculation.
