Pneumatic Rotary Actuator for Robotics




The object of this project is to design, build, and test a rotary pneumatic proportional actuator for use in low cost less accurate robots. Description: The need for a high accuracy ( <0.1 mm) in industrial robots has most often lead to the use of very expensive servo motors to actuate each joint. Robotics for agriculture have a much less stringent requirement for accuracy ( < 2.0 mm) and therefore it may be possible to use low cost proportional pneumatic actuators for joint movement. Several researchers have proposed various designs for such actuators but non are in common use. The project would involve a critical review of the different concepts and then the design, construction and testing of an actuator. The student Design Team benefits by gaining experience in the areas of mechanical design, graphics (CAD), computer interfacing and prototype testing.
