Patent number: 9981383Abstract: Methods, apparatus, systems, and computer readable media are provided for real-time generation of trajectories for actuators of a robot, where the trajectories are generated to lessen the chance of collision with one or more objects in the environment of the robot. In some implementations, a real-time trajectory generator is used to generate trajectories for actuators of a robot based on a current motion state of the actuators, a target motion state of the actuators, and kinematic motion constraints of the actuators. The acceleration constraints and/or other kinematic constraints that are used by the real-time trajectory generator to generate trajectories at a given time are determined so as to lessen the chance of collision with one or more obstacles in the environment of the robot.Type: GrantFiled: August 2, 2016Date of Patent: May 29, 2018Assignee: X DEVELOPMENT LLCInventor: Umashankar Nagarajan
