The invention consists in combining a pneumatic actuator (1) and a part of the position detector (2), the structures containing those - latter assembled hermetically along an edge contour (3), with the structure (8) containing the detector part of the electrical position (2), which ...
When providing an air supply of 12 kPa, each actuator inflates or deflates, indicating potential direction cues [73]. However, limited by its structure and gasbag size, the high precious sensation is still a challenge. The combination of feedback control with the sensation information is the ...

To help contain costs, many designers pursue a hybrid approach to specifying actuator controls, especially when developing systems or subsystems that will be produced in quantity. When a piece of equipment is first undergoing development, engineers may tend to over-specify the instrumentation and put...
