A survey of robot manipulation in contact
In this survey, we present the current status on robots performing manipulation tasks that require varying contact with the environment, such that the robot must either implicitly or explicitly control the contact force with the environment to complete the task.

Robot kinematic calibration used to be carried out with the partial pose measurements (position only) of dimension 3 in industry, while full pose measurements (orientation and position) of dimension 6 sometimes could be considered to improve the ...

A method to formulate a dimensionally homogeneous Jacobian of parallel manipulators [PDF]
This paper presents a general and systematic approach to formulate the dimensionally homogeneous Jacobian, which is an important issue for the dexterity evaluation and dimensional synthesis of f-degrees-of-freedom (DOF) (f ≤ 6) parallel manipulators ...

Generic singularities of robot manipulators [PDF]
The singularities of the differential kinematic map, i.e. of the manipulator Jacobian, are considered. The authors first examine the notion of a generic kinematic map, whose singularities form smooth manifolds of prescribed dimension in the joint space of the manipulator. For three-joint robots, an equivalent condition for genericity using determinants

Generalized Jacobian analysis of lower mobility manipulators [PDF]
Mainly drawing on screw theory and linear algebra, this paper presents a general approach for Jacobian analysis of lower mobility manipulators. Given the definitions of twist/wrench spaces and their subspaces of the end-effector, the underlying ...

Structural Synthesis of Lower-Class Robot Manipulators with General Constraint One
In this research, the structural synthesis of lower-class robot manipulators with general constraint one is investigated. The number of constraints d = 1 and the mobility number λ = 5 for sphere–sphere and sphere–plane combinations of higher kinematic ...

IMPULSE CONTROL OF THE MANIPULATION ROBOT [PDF]
A nonlinear control problem for a manipulation robot is considered. The solvability conditions for the problem are obtained in the class of special impulse controls. To achieve the control goal, the kinetic energy of the manipulation robot is used. When finding analytical formulas for controls, the classical first integrals of Lagrangian mechanics were
