... that they are effective in a real-world setting. Fig. 14 Plots of the ( a ) position and ( b ) orientation estimation error with the self-calibration algorithm (labeled “w/ Calib.”) and with only forward kinematics (labeled “w/o Calib.”) in the experiments of Sec. 5 , where r − r...

...Ravinder Kumar; T. A. Dwarakanath; Gaurav Bhutani; S. K. Sinha The forward kinematics (FK) of a 6-6 universal-prismatic-spherical (UPS) structure of a parallel robot is highly nonlinear, coupled, and has a one-to-many nature of mapping. There exists no close form solution to a forward kinematic...

...Chongjian He; Wei Guo; Yanxia Zhu; Lizhong Jiang Despite significant performance advantages, the intractable forward kinematics have always restricted the application of parallel manipulators to small posture spaces. Traditional analytical methods and Newton–Raphson method usually cannot solve...

...Seongbo Shim; Seongpung Lee; Subin Joo; Joonho Seo This paper presents a new forward kinematic approach for the 3–6 Stewart platform. In the 3–6 Stewart platform, the position and orientation of the moving platform can be determined through kinematic constraint equations that indicate the possible...

... there are eight sets of solutions for the forward kinematic equations. The LAQSPM [ 26 ] with orthogonal base and platform can also be solved directly using the above method. Taking the derivative of Eq. (1) , there is (10) [ ( b 1 × ( R · a 1 ) ) T...
