“…To investigate the dynamics of jaw movement the WJ-series and the JSN/2A chewing robots have been built at Waseda University, Japan [ 13] and Niigata University, Japan [14,15], respectively. They have 3-DOFs of motion and, are made up of a skeleton including condylar housing for the TMJ, artificial muscle actuators, and sensors for both actuated motion and bite force.…”

This paper describes an electro-mechanical and software architecture for the development of an anthropomorphic 6 DOF robotic jaw. The architecture comprises the aggregate of motion components needed to position a prosthetic jaw in 3D space. This architecture frees the jaw kinematics from the dependency of constraints in the mechanical assembly allowing for the fabrication of mechanical systems that can simulate jaw motions beyond human capabilities. The orthogonal and concurrent nature of the structural design makes systems based on this idea potentially the easiest to control. To illustrate our concept two distinct prototypes are produced. Construction of these models resulted in the first two modular anthropomorphic robotic jaws to be built with 6-DOF. Areas of application for this mechanical design include dentistry, speech research, and facial gesture affect research.

“…But the biological characteristics of human mandible system have not been considered sufficiently in these two robots, so they could not reproduce function and environment of the mandible entirely. In food science area, studies (Gibbs and Lundeen, 1981;Takanobu et al, 1998;Xu et al, 2005;Xu and Bronlund, 2010) have contributed much to the mastication robot. The mechanism which Xu et al (2005) put forward existed the problems of singularity so it could not achieve the required mandible movement and bite force during the process of food chewing; In biomechanics area, there are Mark III mastication mechanism (Bowey and Burgess, 2005), JSN chin simulator (Hayashi et al, 1996(Hayashi et al, , 2000, and mandible motion simulator (Galer et al, 2007), etc.…”

Abstract:A jaw robot based on the 6-PUS parallel mechanism was introduced according to the biomechanical properties of mandibular muscles. For a given mandibular trajectory to be tracked, the inverse kinematics solution is derived and Jacobian matrix formulated from differential kinematics is found. Kinematics performances, such as constant orientation workspace and manipulability are simulated via numerical method. These indices show that the parallel mechanism has enough flexible workspace without singularity, and has a good motion transmission performance for human chewing movement. In order to reproduce jaw motions and mechanics that match the human jaw function truthfully with the conception of bionics, the temporomandibular joints (TMJs) are taken into account. Another novel actuation redundant mechanism for the jaw robot is proposed based on mechanical biomimetic principles, which has four degrees of freedom, but is driven by six actuators.
