WebNov 27, 2024 · Detailed models including forward and inverse kinematics, velocity kinematics, and quasi-static dynamics for the steerable needle are mathematically derived based on modern screw theory, which reveals the geometric relationships of robot motions simply and elegantly. WebOther scholars applied screw theory especially the screw system methods [11 , 12 ] to analyse the local motion character- istics of branch motions and constraints of different bifurcated motions. Gan et al. [13 , 14 ] used screw theory to study the mobility changes and bifurcated motion of novel metamorphic parallel mechanisms.
