A multi-axis synchronous somatosensory platform combined with virtual reality image for medical rehabilitation was developed in the project, which mainly provided synchronous motion to improve patient’s body function through interactive technology, spatial positioning, tactile stimulation,situation sense. The physicalmental condition of a patient could be improved during exercise.

Three groups of crank links were applied for the platform which had three degrees of freedom, i.e., heave, roll,pitch. The power was driven by three groups of servo motors. EtherCAT communication transmission with the motion control card was utilized to establish the motion control system. The multi-axis synchronization platform was integrated with VR images to complete the system.

Compared with six electric cylinders, three groups of crank linksservo motors had more low cost. The movement of the platformthe VR image were synchronized to give the rehabilitation patient sense of reality. The physiological signals during rehabilitation were uploaded to the cloud for big data analysis. The physiotherapist can plan more suitable method according to the data.
