The inventor of Roomba has created a weed-slashing robot for your garden

Roomba co-creator Joe Jones has created a garden Roomba for gardens with Franklin Robotics. Tertill uses sensors to identify weeds and cuts them down until they eventually die.

It requires a small raised border to stay in the garden and it needs room between plants to get to all the weeds. The robot is currently on Kickstarter for $US249.
