Navigation
A critical element for the operation of an autonomous is the ability to navigate from one point to another and this is even more challenging when there are tethered slaves and/or a power cord. The autonomous canister vacuum cleaner has both a power cord (for full vacuum power) and a tethered slave, the cleaning head, which is connected via a hose to the main controller. The navigation uses a 2-D map collapsed from the 3-D grid using the height of the robot. Routes are calculated from one point to the next using the geometry of the robot while maintaining a safe distance from objects. In the case of multiple robots, combined routes are calculated for the controller and slave such that they remain in sight of each other as much as possible to enable tracking which results in better localization.
