Robotic arm sensory system of upper limb prosthesis
Robotic arm sensory system brings hope for full-featured life even to physically challenged individuals. At the same time it opens area of the economic growth in terms of biomedicine engineering. Complex of many sensors – proximity, temperature, humidity, CO2 , sensors indicating electromagnetic field, gyroscope, accentometer, strain gauge – creates, all together, a system which allows the robotic arm to transmit relevant information about happenings in its surrounding.
We carried out our robotic arm sensory system project, the software for data proceeding included, which can scan distances and temperature of the surrounding items, the model maps of surrounding environment of the robotic arm and with the usage of the information from gyroscope, accentometer and electromagnetic field sensor define the robotic arm´s location. The system reacts on force effects created while interacting with surroundings.
The project goal – To advance the development of intelligent exoprosthetic supplements.
The goal of the project was to contribute to development of managing complex exoprosthetic supplements by using the designed sensor system based on telemetric, thermometric, motion and contact sensors made for detection of potentially dangerous circumstances in which the arm can occur in case of collision with surrounding objects.
The designed experimental model of the prosthetic arm with 6 actuators was successfully tested for motion simulation. The sensor system detected obstacles in the prosthetic arm model´s surrounding. The control system could identify possible collisions between the arm and surrounding items in right time..
