A closed loop self-calibration method for Delta mechanism and 3-RRR mechanism used in a double parallel haptic device was presented. This approach blocks successively one joint of each parallel mechanism using a simple lockup device and reforms the 3-DOF mechanism to be a 2-DOF one. The parameter errors of the mechanism are identified according to the differences between the sensor output of the redundant chain and nominal model output. Both the condition number and singular value of the error propagation Jacobian are synthesized as a new selection principle of calibration set such that the calibrating process is insensitive to the noise and the calibration precision is increased efficiently. Experiments show that the ratio of maximal error before and after calibrating is 9.6, namely, the setting accuracy of the two mechanisms are increased about 10 times and the error of re-position is less than 0.1 mm and 0.1deg

The traditional drawing system based on the 2-D mouse can not realize the haptic interaction between operators and virtual environment. This is not available for operator to feel the interaction sensitivity. A virtual space painting system based on transparency haptic interaction is proposed. This system uses the admittance type haptic device as the information interaction interface between operators and virtual environment. This paper presents an implicit force control algorithm to adapt the control of the transparency haptic interaction device. This system use the body contact detection, the virtual force generation and smoothness to build the virtual environment. Finally, a virtual painting experiment is done. The result shows that this system could improve the transparency of the haptic interaction. It means that the real artistic creation could be realized on the computer.
