An autonomous mower and a radio-controlled mower are both automated lawnmowers, but there are some key differences between the two.
An autonomous mower works completely autonomously and does not require human operation to operate. It uses sensors and GPS technology to scan the environment and determine the mowing route. Autonomous mowers usually run on batteries and do not require a power or fuel source. They are often used for the maintenance of large surfaces such as sports fields, parks and golf courses.
A radio-controlled mower is remotely controlled by a human operator using a radio remote control. The operator must control the machine and determine the mowing route. Radio-controlled mowers are usually used for mowing steep slopes, hills and areas that are difficult for human mowers to reach.
Basically, the main difference between an autonomous mower and a radio controlled mower is that the former works completely autonomously without human intervention, while the latter relies on a human operator to operate.
