The present invention relates generally to lawnmowers. More specifically, the present invention relates to an electric battery powered and remotely controlled lawnmower. The lawnmower has a rechargeable battery and can be paired wirelessly with a battery powered remote-control or transceiver enabling a user to use the remote-control or transceiver for controlling movements and operation of the mower. The mower does not cause pollution and can be used by individuals of all ages and genders. Accordingly, the present disclosure makes specific reference thereto. Nonetheless, it is to be appreciated that aspects of the present invention are also equally applicable to other like applications, devices, and methods of manufacture.
By way of background, a lawn mower is used for the purpose of maintaining lawns, gardens, grounds, and more. More specifically, the lawnmower is used for cutting, mowing, edging, and blowing the grass. Conventional lawnmowers are pushed by a user for mowing grass which requires physical effort of the user. Lawnmowers are heavy devices which require a considerable effort and are often nearly impossible to push by children, elderly, and individuals with injury and limited physical dexterity. Riding lawn mowers are also a difficult task as the mower may get disbalanced and require effort for maintaining balance of the lawnmower. Pushing and riding lawnmowers can put stress on the body, and can cause dehydration, excessive sweating, cramps, tiredness, and more. Individuals desire an improved lawnmower that can be easily operated by individuals of all ages and physical abilities.
Individuals who cannot mow a lawn themselves often hire help or a professional service for mowing. Individuals spend considerable time to search for a service and often such help and service is expensive. Individuals desire an improved lawnmower that eliminates requirement of a help or a service for mowing due to inability of individuals to mow themselves.
A person for mowing a lawn, grounds, and more, is required to operate the lawnmower and physically operate the lawnmower. A person who may want to sit quietly at a place such as on a chair or while having a drink cannot simultaneously mow. Individuals desire a way by which they can remotely control and operate the lawnmower while being physically remote (at some distance) from the lawnmower.
Most of the lawnmowers available in the market run on gas which is not only expensive but also releases harmful gases and pollutants. The use of lawnmowers therefore becomes a hazard for the environment and therefore, individuals desire lawnmowers that do not cause pollution.
Therefore, there exists a long felt need in the art for a lawnmower that can be fully operated remotely by a user. There is also a long felt need in the art for an improved lawnmower that does not create pollution and does not release harmful gases. Additionally, there is a long felt need in the art for an improved lawnmower that can be operated easily by a remote-control device. Moreover, there is a long felt need in the art for a lawnmower that reduces stress on the body of a user while mowing, and thus preventing exhaustion, dehydration, excessive exertion. Further, there is a long felt need in the art for an improved lawnmower that obviates requirement of a hired helper or a service for mowing due to inability of individuals to mow themselves. Furthermore, there is a long felt need in the art for a lawnmower that can be used by individuals of all ages and genders. Finally, there is a long felt need in the art for an improved garden care tool that enables users to mow a lawn with minimal physical effort and without physically operating the lawnmower.
The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a remotely controlled electric lawnmower. The lawnmower is environmentally friendly and reduces stress on the body while mowing. The lawnmower further comprising a pair of steering front wheels and a pair of rear wheels mounted to a frame; a first gear motor for controlling movement of the steering front wheels and a second gear motor for controlling movement of the rear wheels; a grass cutter or blade positioned at the bottom of the frame for mowing grass; a rechargeable battery for providing electric power to the first gear motor, the second gear motor and the grass cutter or blade; a control unit for receiving wireless instructions from a remote device wherein the wireless instructions are configured to control movement, speed, mowing speed of the lawnmower, whereby a user uses the remote device for remotely controlling lawnmower operations.
In this manner, the remotely controlled electric lawnmower of the present invention accomplishes all of the forgoing objectives and provides users with an improved lawnmower capable of being fully operated with a remote-control. The lawnmower enables for wireless operation via a rechargeable battery and the remote-control. The lawnmower is pollution free and environmentally friendly, reduces stress on the body while mowing, and enables individuals of all ages and abilities to mow a lawn by themselves.
