Trajectory Planning in Joint Space for a Pointing Mechanism Based on a Novel Hybrid Interpolation Algorithm and NSGA-II Algorithm

IEEE Access, 2020
In order to improve the motion stability of a pointing mechanism, the trajectory planning and trajectory optimization were conducted. To obtain better motion stability, the jerk is required continuous.

The kinematics of the redundant $N-1$ wire driven parallel robot [PDF]

, 2013
We address the kinematics of the redundant $N-1$ wire-driven parallel robot, i.e. a robot with $N > 3$ wires connected at the same point on the platform. The redundancy allows one to increase the workspace size.

Human–Robot Cooperative Strength Training Based on Robust Admittance Control Strategy

Sensors, 2022
A stroke is a common disease that can easily lead to lower limb motor dysfunction in the elderly. Stroke survivors can effectively train muscle strength through leg flexion and extension training.

Mechanical Design and Analysis of the End-Effector Finger Rehabilitation Robot (EFRR) for Stroke Patients

Machines, 2021
Most existing finger rehabilitation robots are structurally complex and cannot be adapted to multiple work conditions, such as clinical and home. In addition, there is a lack of attention to active adduction/abduction (A/A) movement, which prevents ...
