Here is a robot that mows your lawn, so you don’t have to. The TigerBot can be driven around like a RC car. It is based on a Worx 56v cordless mower and powered by a 24volt battery. The kit also comes with an integrated camera/microphone, battery charger, remote control with .5 mile range, and everything you need to get started.
The makers are also offering an expansion pack with more batteries, LED light for night moving, and other useful add-ons.
