It is proposed a design and control of series elastic holonomic mobile platform, aimed to administer therapeutic table-top exercises to patients who have suffered injuries that affect the function of their upper extremities. The proposed mobile platform is a low-cost, portable, easy-to-use rehabilitation device for home use. It consists of four actuated Mecanum wheels and a compliant, low-cost, multi degree-of freedom Series Elastic Element as its force sensing unit. Thanks to its series elastic actuation, it is highly backdriveable and can provide assistance/resistance to patients, while performing omni-directional movements on plane. The device helps improving accuracy and effectiveness of repetitive movement therapies completed at home, while also providing quantitative measures of patient progress.
