  • Patent number: 11897132
    Abstract: A technology is described for redundant network communication in a robot. An example of the technology can include a main robotic controller, a local controller in network communication with the main robotic controller, and instructions that, when executed by the processor, transfer first and second data signals between the main robotic controller and the local controller via first and second network channels. The first data signal is sent over the first network channel, and the second data signal is sent over the second network channel. The instructions compare the first data signal with the second data signal to determine signal integrity of the data signals; determine degradation of the first data signal if the signal integrity is less than the signal integrity of the second data signal; and select the second data signal for processing if degradation of the first data signal is determined.

  • Patent number: 11833676
    Abstract: An exoskeleton operable to prevent unsafe operation can comprise a plurality of joint mechanisms and a plurality of sensors comprising configured to generate sensor output data associated with at least two joint mechanisms. The exoskeleton can comprise a controller configured to receive the sensor output data; combine the sensor output data; and determine whether the combination of the sensor output data from the first and second sensors satisfies an error condition in relation to at least one defined criterion. The existence of an error condition can be indicative of an anomalous operating state of the exoskeleton, such as a malfunction or an (impending) anomalous kinematic movement. The controller can also combine command signals to be transmitted to two or more joint mechanisms to determine another anomalous operating state to prevent unsafe operation. Associated software and methods are provided.
