Rehabilitation robotics is considered as a specific focus of biomedical engineering. In this field, clinicians, therapists, and engineers collaborate to help rehabilitate patients. Prominent goals in the field include developing implementable technologies that can be easily used by patients, therapists, and clinicians enhancing the efficiency of clinician's therapies and thereby enlarging the ease of activities in the daily lives of patients. From the past decade, the number of rehabilitation robots has increased but they are very limited due to the clinical trials. Many clinics have trials but did not accept the robots because they wish they were remotely controlled. Making Robots involved in the rehabilitation of a patient has some advantages. One of the positive aspects is the fact that you can repeat the process as many times as you desired. Another positive aspect is the fact that you can get accurate measurements of their improvement or decline. You can get the exact measurements via sensors on the device. While the robot is about to take measurements, one needs to be careful because the robot may be disrupted. The rehabilitation robot can be able to apply constant therapy for long periods. The rehabilitation robot is a useful machine to use according to many therapists, scientists, and patients who have undergone the therapy. In the process of recovery, he is unable to understand the patient’s needs like a well-experienced therapist would. The robot is unable to understand now but in the future, the device will be able to understand. Another advantage of having a rehabilitation robot is that there will be no physical effort to put into work by the therapist.
