REMOTE CONTROL LAWN MOWER
Welcome to my remote control lawn mower site. My name is Brian
Nagamatsu. I am a Mechanical Engineer and have dreamed for years about
developing a remote controlled lawn mower or robotic lawn mower to mow
difficult areas of my lawn. I have a steep hill in my back yard that I
have slid off of many times.
About 15 years ago I even started trying to develop a
Radio control lawn mower. I determined that a remote control lawn mower
must be powerful enough to mow the grass and also must have a powerful
propulsion system. I looked into using electrical servos or pneumatic or
hydraulic actuators for steering the lawn mower wheels. I ran into
the problem that the operating time would be limited by the life of on
board batteries. The remote control lawn mower would have to be stopped
and the batteries recharged.
Additionally, I determined that the cutter blades would
have to be powered by a gasoline engine in order to cut through heavy
dense grass. Electric motors driven by on board batteries would have to
spin small high speed blades and would have a hard time mowing through
grass that was long and wet. Also the on board batteries would also be
quickly drained with by the electric motors.
For years I was perplexed. Then I discovered a remote
controlled mower that solved these problems. The remote control mower uses
a hybrid system providing a brilliant solution to all the problems.
The mower combines a powerful gas engine to spin the
cutting blade with an electical drive and electrical generator/battery
system. The traction and steering wheels are driven by high power
reversible direction motors that are powered by the generator/battery system.
The battery is continuously charged by the on board generator driven by
the gas motor. Therefore, the battery does not run out of charge.
Additionally, the remote control mower has a very smart
controller system (The BRAIN) that constantly motors and controls the
electrical propulsion and charging system.
I used to hate mowing the lawn manually every two days
during the growing season, but now I cannot wait to go run my remote
control mower. It is so fun finding the fastest ways to mow the lawn. On
really hot days I can sit in my airconditioned house and look out a
window to operate the mower. I also enjoy watching other guys sweating out
there with their manual mowers.
