This article presents an efficient scheme based on fractional order sliding mode control
approach for precision tip position control of a single link flexible robot arm. The proposed …

Unpredictable and time-variable adhesion force between the rubber unstacking robot and
the rubber block is generated, which makes it difficult for the robot to smoothly complete the …

The hybrid arms robot (HAR) is a new modified robot which consists of a rigid link (RL) and a
flexible link (FL), and it carries a laser head at the end-effector for laser contour machining …

Bipedal robots by their nature show both hybrid and underactuated system features which
are not stable and controllable at every point of joint space. They are only controllable on …

Previous works have developed impedance control to increase safety and improve
performance in contact tasks, where the robot is in physical interaction with either an …
