WebThe analysis makes use of a joint-space orthogonal decomposition procedure involving the so called reaction null space. The article focuses on the specific case of a nonredundant arm and a reaction null space in terms of base angular motion. We further show that with proper post-impact control it is possible to transfer the whole angular ... WebWe should be checking that v1+v2 is in the nullspace. What it means to be in the nullspace is that A (v1+v2) should be the zero vector. But A (v1+v2)=Av1+Av2 (because matrix transformations are linear). Now if we assumed v1 and v2 are in the nullspace, we would have Av1=0 and Av2=0. So A (v1+v2)=Av1+Av2=0+0=0.

WebWith the increase of on-orbit maintenance and support requirements, the application of a space manipulator is becoming more promising. In actual operation, the strong coupling of the free-floating space robot itself and the unknown disturbance of the contact target caused a major challenge to the robot base posture control. Traditional Reaction Null … WebUsing a concept called Reaction Null Space, the manipulator dynamics is totally decoupled from the base dynamics. As a consequence of the decoupling, feedback control gains can be determined in a straightforward manner. We examine the simultaneous performance of the following two tasks: (1) base vibration suppression and (2) end-point path ...
