Autonomous operation device, system, and control method

A control method for an autonomous operation device, comprising:

• receiving an instruction from a user via an input device disposed on the autonomous operation device, wherein the instruction comprising comprises a specified schedule set by the user for operation of the autonomous operation device;
• obtaining, via a sensor, a boundary length for operation of the autonomous operation device;
• storing, in a memory disposed on the autonomous operation device, a computer program executable on a processor connected to the memory and to the input device;
• receiving, by the processor, the specified schedule from the user via the input device, wherein the specified schedule encompasses a first duration for operation of the autonomous operation device, wherein the first duration comprises a plurality of first time periods;
• determining, by the processor, a planned schedule according to the boundary length, wherein the planned schedule encompasses a second duration for operation of the autonomous operation device, wherein the second duration comprises a plurality of second time periods;
• determining, by the processor, at least one of a number of starting points for the autonomous operation device and positions of the starting points for the autonomous operation device according to the boundary length, wherein and the autonomous operation device begins working after arriving at a pre-determined starting point;
• comparing, by the processor, the first duration with the second duration;
• and
• at least one of
• if the second duration is less than the first duration, operating the autonomous operation device according to an operation schedule corresponding to the planned schedule;
• and
• if the second duration is greater than the first duration, operating the autonomous operation device according to an operation schedule corresponding to the specified schedule.
