Robotic arm equation of motion
WebContinuing our abstractions, we find that the equations of motion of a general robotic manipulator (without kinematic loops) take the form (3) M ( q) q ¨ + C ( q, q ˙) q ˙ = τ g ( q) + B u, where q is the joint position vector, M is the inertia matrix, C captures Coriolis forces, … WebOverall, this equation looks like f equals m-a plus a gravity force, except that the accelerations of the masses depend not only on the joint accelerations but also products …
