  • Active Vibration Control of an Axially Translating

    In this paper, we aim to study the active vibration control of an axially translating robot arm with rotating-prismatic joint using self-sensing actuator. Lagrange’s equation with the assumed mode method is employed to derive the equations of motion. And the displacement and velocity control law is used to configure the self-sensing actuator. 2.

  • Prismatic Joint - an overview | ScienceDirect Topics

    Robot joints are either rotary or prismatic. A rotary joint is like the human elbow joint, a simple hinge, whose motion is described by a joint angle. A prismatic joint allows linear motion in one direction, such as the plunger of a bicycle pump or the shock absorbers of a car, whose motion is described by a joint displacement. Robot manipulators comprise combinations of rotary and prismatic joints, usually in …

    2020-6-17 · Each joint is considered an axis. The more joints a robot has, the bigger its range of motion gets (also called degree of freedom). Articulated robots are highly flexible as all their joints are revolute, meaning they can rotate, as opposed to prismatic joints, which move linearly. They have a limited ability in avoiding obstacles though.
