Injuries in certain parts of the feet can cause a person to have difficulty in walking or running if it is not treated through physiotherapy. In Malaysia, therapy centers only provide a service or the use of basic tools that are not efficient as more sophisticated equipment requires a high cost. In fact, exercise requiring close monitoring physiotherapist are also at a high cost. Therefore, using robot therapy is a new technology that can provide an alternative way to solve this problem. The implementation of this project has produced a robotic physiotherapy which has one degree of freedom, portable and inexpensive way to help the movement of the patient's leg. It covers basic electrical circuits, mechanical components, programming and has been combined with an interactive game as the main driver. ROLEP (Robotic-Leg-Physiotherapy) is able to help patients through the therapy process. It was built using CT-UNO as its microprocessor connected to MD10-C which acted as the motor driver. The interactive game produced by using Unity game software is a key driver in getting rid of boredom and reduce pain. As a result, ROLEP designed can operate well within its range of the patient's weight. It has the advantage of portability and easy to use by the patients. ROLEP expected to help patients undergoing therapy process more efficient and interesting in the process of recovery.
