Solar-powered 'Tertill' robot autonomously weeds gardens

For those tired of the never-ending task of weeding, one set of engineers has the answer: a robot that autonomously clears up your lawn. The machine 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 water-proof so can be left outside in the rain and does not need to be plugged in to charge. Experts have developed a machine that automatically roams the garden and uses sensors to detect weeds sprouting from the soil, which it then cuts down. As well as the ability to pair with smartphones through Bluetooth, the Tertill also has a USB port for charging during cloudy weeks.
