Robotics is improving very fast and it is used everywhere. Robotics is a hybrid of mechanics, electrical engineering and computer science. The thing I like in this field is that if you are working hard you can develop a lot of things and you can provide many useful devices for people. To reach this aim, my main focus is on medical robots and devices. But we are working in other areas. Besides, we are working in haptics field because it helps us to provide practical systems like as systems for tele-rehabilitation and tele-medicine. Thus, combining haptics and robotics will make a very fascinating area which helps us to make a lot of profitable devices. I started my work with mechanism design and then I developed my works by building and controlling different robots. This kind of interdisciplinary work help me to have different ideas and make creative things.

Abstract: One of the most restricting conditions for any living being is the loss of mobility. For humans, quadriplegia is the most extreme form. Different causes like spinal cord or brain injuries resulting in various degrees of paralysis of all four limbs. In the most serious cases even the ability to feel is gone below the injury resulting in an absolute dependency on others. Technical devices are already able to help those affected in many ways. To regain some of their independence, a robot actuating their body and giving them their mobility back could be one approach. Since their conditions affect the ability to interact with a device the choices for an interface controlling device are limited. In this paper, a novel design for a one degree of freedom device for paralyzed patients is presented and a new concept of using hydraulic actuators and their usage is shown. This device is focusing on the wrist extension and flexion. It is considered as a demonstration platform for a new actuation and comfort approaches for assistive devices. Since moving the human body for manipulation of objects will require high output forces, using a hydraulic system is a good option for actuating the device. Thus, after designing the device, a suitable actuator has to be chosen. One of the problems in using hydraulic systems is their hard controlling task. For controlling this hydraulic actuator, an impedance controller is proposed. For evaluating the controlling system, two different experiments are designed and their results are explored. According to the results, it is concluded the impedance controller can fulfill all of the requirements and according to its simplicity, it could be counted as a good option for controlling this kind of device.} number={2
