Fig. 1  Concept of 'transparency' in human-assistive rehabilitation robots: (a) Conventional robot: The robot's inherent dynamics constrain the user's movement. (b) Conventional transparency concept: The interaction force between the robot and the user is zero, suggesting no physical assistance. (c) Proposed transparency concept for essential human assistance: Despite the presence of an interaction force indicating assistance, the robot's inherent dynamics do not constrain the user's movement. This transparency is crucial for patients with moderate to severe impairments who may not be able to move independently; in such cases, the proposed interaction force provides necessary assistance without restricting movement.
