Abstract
There is provided a computer-implemented method for determining feasible joint trajectories for an n-dof (n>5) robot in a rotation invariant processing of an object, such as milling, painting, and welding. The method includes the steps of receiving geometric data representing the object; receiving geometric data representing the processing tool; receiving a tool path X(t), where t is time; searching for feasible paths q(t) using IK (t) and q(t) as set of possible solutions at time t, wherein q(t) defines positions of all the joints in the robot as function of time, q(t) defines the rotation of a tool flange around the tool axis at time t, and IK (t) defines the inverse kinematics solutions for a given X(t) and q(t); and determining, from the geometric data and X(t), how the joint path q(t) should be chosen so as to comply with one or more optimisation criteria.
