The aim of our study is to construct a Humanoid with enhanced bipedal walk, which can be utilized in the Medical Sector, as an effective substitute for Artificial Limbs. With reference to the human body, we have designed a humanoid such that the joints are exposed to zero friction, and the efficiency of the motor is increased. The natural phenomenon in the human to adjust the center of gravity and...
Now more than ever, progresses in information technology applied to rehabilitation robotics give new hopes to people recovering from different kinds of diseases and injuries. Beside the standard application of EMG signals to analyze disabilities or to track progress in rehabilitation, more focus has been put on controlling robot arms and exoskeletons. In recent years, biomechanists have developed...
Entry position of the graft is very important in anterior cruciate ligament (ACL) reconstruction. However the determination of entry position is very difficult to the surgeon. In this paper, a navigation and evaluation system assisted by the 6-DOFS robot is implemented for the simulation evaluation and planning insertion points based on quadrant method for the femur and Sta??ublis method for the tibia...
Summary form only given. Clinical Problem: the knee joint has in the femur as well as tibia very long leaver arms. Therefore a misalignment of only 2 degrees of the femur already results with a 2 cm distance of the mechanical axis to the centre of the femoral head. This leads to an asymmetric load distribution and so increased wear. Material and methods: the Galileo Navigation system allows the kinematic...
A new set of lower limb orthoses was developed for the WalkTrainer project. This mobile reeducation device for paralyzed people allows overground gait training combining closed loop electrical muscle stimulation and lower limb guiding while walking. An active body weight support system offers precise body weight unloading during locomotion. A 6 DOF parallel robot moves the pelvis in any desired position...
For femoral fracture reduction, we have developed a surgical robotic system. Indirect traction is employed in our system. Indirect traction in fracture reduction is a generally used surgical method for preventing complications such as bone splits caused by high stress on bones. For traction, a patientpsilas foot is gripped by a jig and pulled to the distal side. Indirect traction has the advantage...
