The present invention relates to a parallel robotic structure (1) with six degrees of freedom which comprises movable bases (2, 21, 22, 23, 24, 25, 26, 27, 21', 22', 23', 24', 25', 26', 27', 28') that can be rotated or translated, and a platform (3) coupled with the ...
More specifically, would additional degrees-of-freedom in the exoskeleton that allow the human trunk to translate and rotate, and the hips to abduct/adduct increase human gait adaptation with an exoskeleton?关键词: gait analysis medical robotics path planning patient rehabilitation prosthetics ALEX I ...
This construction method extends the precision of the rotary drive to two degrees of freedom and obviates the apparatus required in other methods to transmit torques from the fixed reference frame to the second driven member.doi:US5429015 ASteven D. Somes...
The robotic-OCT scanner was constructed by attaching an OCT probe to a six degrees of freedom (DOF) robotic arm (Dobot, China) using a custom-designed adapter. The OCT probe consisted of a fiber collimator, a galvo scanner and an objective lens. The robotic arm had a payload of 3 kg...
In this paper, we present optimal control for movement and trajectory planning for four degrees-of-freedom robot using Fuzzy Logic (FL) and Genetic Algorithms (GAs). We have evaluated using Fuzzy Logic (FL) and Genetic Algorithms (GAs) for four degree-of-freedom (4 DOF) robotics arm, Uncer...

The problem of path planning for robotic manipulators with redundant and nonredundant degrees of freedom is addressed. It is assumed that the motors for each joint are capable of achieving the commanded velocity within limits. Thus, the dynamic model is simplified and the main complexity is that ...
A robotic device has a base and at least one finger having at least two links that are connected in series on rotary joints with at least two degrees of freedom. A brushless motor and an associated controller are located at each joint to... Townsend, William T 被引量: 26发表: 2007年 ...
We created an experimental setup to investigate how individual motor skills contribute to the performance of a human user of a supernumerary robotic thumb; i.e. a robotic augmented human. To this end, we have created a 2 degrees of freedom (DoF) robotic finger that users can wear on the ...
