Studies on tele-surgery
The myoelectric upper limb prosthesis has been developing for a person who lost the arm above the elbow. The artificial arm is activated based on the EMG signals to generate the user's intended movement.
Inner skeleton device is a body embedded motor actuated device that can be replaced from the human bone structure like an artificial joint. The study is in the early stage, but showing the effectiveness to measure the EMG signal from inside the body. The video is posted here.
Knee Joint Simulator
The knee joint simulator has been developing in order to evaluate the performance of the artificial knee joint. The simulator can generate the human knee joint motion.
Hip Joint Simulator
The hip joint simulator has been developing in order to evaluate the performance of the artificial hip joint. The simulator can generate the joint contact force as well as the human daily hip joint motion. The mechanism of an artificial hip joint dislocation has been analyzed using the simulator.
Haptic device using parallel mechanism
In this research, a new parallel mechanism DELTA-R is proposed for a new haptic device within high quality force display capability and operability. The key features of DELTA-R comparing with conventional parallel mechanisms are: a redundant actuation, a small footprint, and a wide working area. The video is posted here.
Neurosurgical motion base
Neurosurgical motion base is a 8 DOF robotic arm for positioning a surgical tool. The neurosurgical motion base is developed as a mount-type surgical robot on a conventional surgical head frame, therefore, it is possible to realize a quick installation. The video is posted here.
Surgical Manipulator based on Softrobotics
The mechanism was developed for a surgical robot, which can implement various surgical treatment devices inside of the manipulator. The spring-link mechanism is a simple combination of a flat spring and a rigid link with a passive joint connection. The video is posted here.
Soft parallel mechanism for optical industry
Compliant-parallel mechanism is the mechanism that all joints are composed by compliant joints in a parallel structure. The motion of compliant joints can be guided by mechanical constraints from the parallel structure; thus the mechanism can be precisely driven.The video is posted here.
