Framework Comparison Between a Multifingered Hand and a Parallel Manipulator
نویسندگان
چکیده
In this paper we apply the kineto-static mathematical models commonly used for robotic hands and for parallel manipulators to an example of handplus-object (parallel manipulator) with three fingers (legs), each with two phalanges (links). The obtained analytical matrix expressions that define the velocity and static equations in both frameworks are shown to be equivalent. This equivalence clarifies the role of the grasp matrix versus the parallel manipulator Jacobian. Potential knowledge transfer between both fields is discussed in the last section.

متن کاملKinematic and Dynamic Analysis of Tripteron, an Over-constrained 3-DOF Translational Parallel Manipulator, Through Newton-Euler Approach
In this research, as the main contribution, a comprehensive study is carried out on the mathematical modeling and analysis of the inverse kinematics and dynamics of an over-constraint three translational degree-of-freedom parallel manipulator. Due to the inconsistency between the number of equations and unknowns, the problem of obtaining the constraint forces and torques of an over-constraint m...
متن کاملDexterous Workspace Shape and Size Optimization of Tricept Parallel Manipulator
This work intends to deal with the optimal kinematic synthesis problem of Tricept parallel manipulator. Observing that cuboid workspaces are desirable for most machines, we use the concept of effective inscribed cuboid workspace, which reflects requirements on the workspace shape, volume and quality, simultaneously. The effectiveness of a workspace is characterized by the dexterity of the manip...
متن کامل3-RPS Parallel Manipulator Dynamical Modelling and Control Based on SMC and FL Methods
In this paper, a dynamical model-based SMC (Sliding Mode Control) is proposed fortrajectory tracking of a 3-RPS (Revolute, Prismatic, Spherical) parallel manipulator. With ignoring smallinertial effects of all legs and joints compared with those of the end-effector of 3-RPS, the dynamical model ofthe manipulator is developed based on Lagrange method. By removing the unknown Lagrange multipliers...
متن کاملForward Position Kinematics of a Parallel Manipulator with New Architecture
The forward position kinematics (FPK) of a parallel manipulator with new architecture supposed to be used as a moving mechanism in a flight simulator project is discussed in this paper. The closed form solution for the FPK problem of the manipulator is first determined. It has, then, been shown that there are at most 24 solutions for FPK problem. This result has been verified by using other tec...
