The new robot for rehabilitation is made according to the principleparallel spherical manipulator. As planned, the patient puts his hand into the apparatus and holds on to the handle on the upper mobile platform. At this time, the human elbow joint is fixed on a special stand. In the process of work, the moving elements of the machine develop the carpal joint of the hand: they smoothly move the hand down - up, right - left and twist it in both directions.
Every year 450,000 are registered in Russiacases of stroke and only 10% of patients return to work after illness. Stroke often leads to impairment of a person’s motor activity, and the use of robotic tools in post-stroke rehabilitation has already shown positive dynamics in restoring mobility functions both in the early stages of the disease and in patients with chronic impairments

According to the developer, the design of the devicediffers from classical parallel spherical manipulators. Her robot is made in an asymmetric design, which allows to increase its useful working space to the space of standard hand movements. This makes the robot compact and easy to use.
For this project I developedmathematical model and wrote the program code. The model calculates the robot's movements down - up, right - left and twisting, that is, forward, reverse and differential kinematics. The solution to these problems - verification of kinematics - was carried out on the first prototypes of the device. However, the patient has not yet participated in these trials
