Abstract
A method for minimizing the rate of collision of a mobile robotic device. A mobile robotic device selects controls comprised of sets of actions to navigate through a workspace. Controls resulting in non-collisions cause the system to earn a positive reward. Controls resulting in collisions cause the system to earn a negative reward. Cumulative rewards over the course of a work session are compared to the cumulative rewards of other work sessions. A policy is defined based on outcomes of prior work sessions to minimize the expected number of collisions.
Claims7
A method for minimizing the rate of collisions incurred by a mobile robotic device comprising:
- selecting controls comprised of sets of actions to navigate through a workspace;
- carrying out the selected controls by a mobile robotic device;
- detecting whether a collision has been incurred by the mobile robotic device;
- and
- calculating and assigning varying levels of rewards to the mobile robotic device system based on the type of obstacle encountered and the success or failure of controls in avoiding collisions and carrying out controls.
A method for minimizing the rate of collisions incurred by a mobile robotic device comprising:
- selecting controls comprised of sets of actions to navigate through a workspace;
- carrying out the selected controls by a mobile robotic device;
- detecting whether a collision has been incurred by the mobile robotic device;
- and
- calculating and assigning rewards to a mobile robotic device system based on the success or failure of controls in avoiding collisions and carrying out controls;
- wherein assigned rewards are decreased over time within a work session by a decay factor to account for a long term reduction in run time due to deterioration of battery life over time.
