Stiffness‐Programmable Origami Robots With Tendon‐Driven Actuation via Multimaterial 3D Printing
Advanced Robotics Research, EarlyView.Motion diversity is achieved in a tendon‐driven origami robot through programmable stiffness rather than modified actuation. Multimaterial 3D printing embeds soft creases, modular inserts redirect identical tendon inputs into distinct behaviors, and variable‐stiffness inserts enable real‐time switching.

Control of Gear Transmission Servo Systems With Asymmetric Deadzone Nonlinearity [PDF]
IEEE Transactions on Control Systems Technology, 2016 This brief deals with the output control problem of gear transmission servo systems with asymmetric deadzone nonlinearity between states. To overcome the difficulty of controller design due to the nondifferentiability of the deadzone, a brand new differentiable asymmetric deadzone model is put forward, which provides an additional design degree of ...
