A US firm has developed a robot that autonomously does weeding in the garden.
The robot roams the garden and uses sensors to detect weeds sprouting from the soil, which it then cuts down using a small string trimmer.
The robot, called Tertill, is solar powered and waterproof, so can be left outside in the rain and does not need to be plugged in to charge.
As well as the ability to pair with smartphones through Bluetooth, the Tertill also has a USB port for charging during cloudy weeks.
