Mowing the lawn is not a lot of fun. The good news is plenty of companies are building robomowers to get it done without you having to break a sweat. The Kobalt Electric Mower Robot by SuperDroid Robots comes with remote control, so you can cut grass with less effort.
The robot is driven by 13-inch tires. It has a steel frame and is based on a wheelchair motor system. It ships with 2 x 12V 35Ahr SLA batteries.
