Kinesin Moves by an Asymmetric Hand-Over-Hand Mechanism

The inchworm motor is commonly used in scanning tunneling microscopes (STMs). An STM requires nanometer scale control of its scanning tip near the material it is observing. This control can be accomplished by connecting the scanning tip to the shaft of the inchworm motor. The inchworm motor, in turn, allows control in a direction normal to the plane of the observed material's surface. Movement across the surface is commonly referred to as movement in the x-… WebInchworm-styled locomotion is one of the simplest gaits for mobile robots, which enables easy actuation, effective movement, and strong adaptation in nature. However, an agile inchworm-like robot that realizes versatile locomotion usually requires effective friction force manipulation with a complicated actuation structure and control algorithm.
