  • How to reduce jerk in linear motion systems

     · The way to avoid jerk is to reduce the rate of acceleration or deceleration. In motion control systems, this is done by using an S-curve motion profile, instead of the "jerky" trapezoidal profile. In a trapezoidal move profile, acceleration occurs instantly (at least in theory) and jerk is infinite.

  • Robotic Mechanisms – PULLEYS and BELTS 51045

     · Pulleys and Belts transfer rotating motion from one shaft to another. Essentially, pulleys are gears without teeth that depend on the frictional forces of connecting belts, chains, ropes, or cables to transfer torque. If both pulleys have the same diameter, they will rotate at the same speed. However, if one pulley is larger than the other, mechanical advantage and velocity ratio are gained.
