Abstract: A method for performing robot dynamic path modification using a remote tool center point (RTCP) coordinate frame, for applications such as material dispensing. A processing tool is fixedly mounted in a workcell and the robot holds and moves the workpiece during the processing. The RTCP coordinate frame is defined at the tip of the tool. A nominal processing path on the workpiece is defined, and a prescribed offset distance from the tip of the tool to the workpiece is defined. A sensor measures the actual offset distance from the tool tip to the workpiece. A controller applies the offset in the RTCP coordinate frame and calculates robot motions causing the robot to move the workpiece nominal path past the tool tip at the offset distance. The controller converts the offset from the RTCP frame to a workcell frame, and performs inverse kinematics calculations to generate robot joint motion commands.

Abstract: An approach is provided for dynamically identifying a danger zone for a predicted traffic accident and generating a warning about the accident. From a monitoring device at a first location, information about traffic conditions for vehicles at time T0 and at least one subsequent time T0+t is received.

Within the response time, a dual artificial intelligence (AI) model using shallow and deep learners applied on historical accident data is employed. Based on the dual AI model and the traffic conditions, an accident involving vehicle(s) in the traffic is predicted to occur in a zone. A warning about the accident is generated and sent to device(s) in the vehicle(s). The warning is presented to driver(s) of the vehicle(s).
