Kinematics

Kinematics• Cable lengths are measured from the top of the

pulleys.

(x, y, z) is the pod position and (xi, yi, zi) is the position of the top of the ith pulley

• The position of each pulley is given by:

Kinematics•In terms of cable lengths, given a

speciefied ceilbot position (x, y, z), the required lengths are:

Kinematics•For solving this equation we will need 3

actives cables . Here we choose l1, l2, l3 for which (x, y, z) are given by:
