Abstract
Methods, apparatus, systems, and computer readable media are provided for generating updated robot actuator trajectories in response to violation of torque constraints and/or other constraints in previously generated robot actuator trajectories. 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 generated trajectory of each of the actuators is analyzed to determine whether a violation of at least one additional constraint occurs. In response to determining violation(s) of the additional constraint, one or more new kinematic motion constraints of the actuators are determined based on the violation(s). The real-time trajectory generator generates updated trajectories based on applying the new kinematic motion constraints in lieu of their counterparts used in generating the trajectories that included the violation(s) of the additional constraint.
