For quantifying the variations in lower-limb monoliphic muscles stress in sprint running and analysing its influence on sprint running, in this study eight excellent sprinters' two-dimensional kinetic data, the data of the ground's counterforce and the electromyography signal are collected concurrently and the variations in lower-limb monoliphic muscles stress is optimized. Results reveal in sprint...
For the typical non-linear robot control system, this paper proposes a class of sliding mode variable structure control method (SMVSC) based on RBF neural network, and the controller's output is added a low-pass filter. A two-joint robot is the research object, This method apply a powerful learning and processing power of RBF network as the sliding mode controller for uncertain part, and resolves...
While a redundant robot is still able to continue the desired task in the presence of locked joint failures, its end-effector error both at the instant of locking joint and in post-failure operations will increase obviously. This work discusses the path error of a redundant robot in fault tolerant operations for locked-joint failures. First, the analytical formula of the optimal joint velocity with...
