Latest Patents

Joseph A Barnett holds a patent for a "Plural robotic drive." This robotic system features two joints that move a common load-bearing member along a designated path for precise load positioning. Each joint is equipped with a linear electric motor and a feedback loop that drives the motor accurately in response to a commanded position signal. Additionally, a true position signal is provided by sensor apparatus located alongside the track of each linear motor. The system incorporates cross-coupling circuitry that connects with the sensor apparatus of each joint to generate signals representing differences in positional error and speed. These signals are injected into the feedback loops of the joints to synchronize their travel. The design also employs window comparator circuitry to introduce variable gains to the feedback loops for positional error and velocity values exceeding reference values. Furthermore, simultaneous injection of phase lead angle to the electric motors facilitates a transition to high-speed mode while maintaining synchronized operation.
