  • Method and system for robotic adaptive production
    Patent number: 10668623
    Abstract: A method for robotic adaptive production includes modifying program instructions online while performing production activities in response to detecting a change in the production environment. A robotic adaptive production method includes modifying program instructions online while performing production activities to minimize a production task cycle time or improve a production task quality. A robotic adaptive production method includes estimating a relationship between a control parameter and a sensor input; and modifying the control parameter online to achieve an updated parameter based on the estimating. A robotic adaptive production method includes receiving sensor input relating to robotic performance during the performance of production tasks and online optimizing a process parameter based on robotic performance during the performance of the production tasks.

  • Electronic circuit for tactile sensors
    Patent number: 4591944
    Abstract: An electronic circuit adapted to receive conditioned force signals from a three-axes load cell mounted on the arm of a robot and provide a stop signal for use by a controller of the robot. The circuit compares the sum of the absolute value of the forces with a variable reference signal. A force trip relay and a masking relay are connected in parallel to provide the stop signal when both the resulting sum is greater in value than the reference signal and the robot is in an operating condition in which high forces do not normally occur.
