Modeling Parallel Robot Kinematics for 3T2R and 3T3R Tasks Using Reciprocal Sets of Euler Angles

open access: yesRobotics, 2019
Industrial manipulators and parallel robots are often used for tasks, such as drilling or milling, that require three translational, but only two rotational degrees of freedom (“3T2R”). While kinematic models for specific mechanisms for these

Kinematic and Dynamic Synthesis of Geared Robotic Mechanisms [PDF]

open access: yesJournal of Mechanical Design, 1993
This paper describes a methodology for the design of geared robotic mechanisms. It is shown that certain gear-coupled manipulators can be designed to possess kinematic isotropy property at a given end-effector position. For these gear-coupled manipulators, the train values can be treated as a product of two-stage gear reductions.

Overcoming Kinematic Singularities for Motion Control in a Caster Wheeled Omnidirectional Robot

open access: yesRobotics, 2021
Omnidirectional planar robots are common these days due to their high mobility, for example in human–robot interactions. The motion of such mechanisms is based on specially designed wheels, which may vary when different terrains are considered. The usage

Multijoint passive elastic spine exoskeleton for stoop lifting assistance

open access: yesInternational Journal of Advanced Robotic Systems, 2021
In the task of carrying heavy objects, it is easy to cause back injuries and other musculoskeletal diseases. Although wearable robots are designed to reduce this danger, most existing exoskeletons use high-stiffness mechanisms, which are beneficial to ...
