Such employment is manual and laborintensivework. In other fields of endeavor, robots have been shown to be particularly suited t o performroutine manual tasks. Robots have yet to sufficiently penetrate the la ndscaping and groundskeepingmarkets, however. Typical robotic smart lawnmowers use randomness and sheer persistence to mow grass.This approach has not proven to be sufficiently efficient and effective to penetrate the landscaping andgrou ndskeeping markets. As a result, there is a need for improved smart lawnmowers.”

An accumulator is a device for producing electricity whereinchemical ener gy is converted into electrical energy. The chemical energy comes from electroch emicallyactive compounds deposited on at least one face of electrodes arranged in the accumulator. Electricalenergy is produced by electrochemical reactions d uring a discharge of the accumulator. The electrodes arearranged in a container and are electrically connected to current output terminals which provide electr icalcontinuity between the electrodes and an electrical consumer with which the accumulator is associated.
