Posture control and trajectory formation during arm movement.
One hypothesis for the generation of spatially oriented arm movements by the central nervous system is that a desired joint position is determined by the ratio of the tensions of agonist and antagonist muscles. According to this hypothesis, the transition between equilibrium states should be solely a function of the contraction time of the motor units and the mechanical properties of the arm. W...
متن کاملPicking Robot Arm Trajectory Planning Method
The picking robot arm is scheduled to complete picking tasks in the working space, to overcome the shaking vibration to improve the picking stability, its movement should follow specific consistence trajectory points. Usually we should give definite multiple feature picking points, map their inverse kinematics to the joint space, establish motion equation for the corresponding point in the join...
متن کاملTrajectory Control of a Computer Arm
This paper describes the programming of a computer controlled arm. The programming is d i vided logical ly into planning and execution Communication between planning and execution is by a data f i l e which specifies the arm trajectory with reapect to time, and actions that the arm should perform. The servo program which moves the arm along the trajectory is based on Legrangian mechanics and ta...
متن کاملTwo - Arm Trajectory Planning in a Manipulation
This paper addresses the trajectory planning problem for a task which requires positioning and orienting an object rmly grasped by two hands at a visually speciied goal connguration in the horizontal plane. The motor task involves three degrees of freedom (two translational and one rotational), and the motions of the arms are constrained by the physical coupling through the held object. Experim...
متن کاملNeural dynamics of planned arm movements: emergent invariants and speed-accuracy properties during trajectory formation.
A real-time neural network model, called the vector-integration-to-endpoint (VITE) model is developed and used to simulate quantitatively behavioral and neural data about planned and passive arm movements. Invariants o farm movements emerge through network interactions rather than through an explicitly precomputed trajectory. Motor planning occurs in the form of a target position command (TPC),...
