For anyone who hates doing yard work, your new best friend may have arrived. A robot can autonomously shovel snow, collect leaves and cut grass.
“We’re trying t o help people not spend time on yard work,”said Steven Waelbers, the designer of t he robot. “We want people to enjoy t heir free time with their family.”The electric robot can run by itself in right directions with the help of two beacons(信号塔) that must be placed in the yard. the robot includes a camera and ultrasound sensor (超声传感器) that Waelbers said would stop quickly when it finds pets and people.
Owners of the robot will need t o regulate t he values stored in the robot. then it will confirm the task it’s going to take. Before the robot operate by itself, an owner must manually wheel it around the yard 一 taking it around any obstacles like trees, bushes or mailboxes. By doing this, the robot is taught how long and wide the lawn is, and won’t accidentally(不小心) destroy your rose hush or run to the neighborhood.
Once this setup is complete, and the $3,999 robot has been trained on where to cut grass, rake leaves and shovel snow, it operates without any supervision.
Waelbers has always loved to build robots and play with electronics. He started work on a high-tech company after his father asked him to make a robot that would shovel snow for him. Waelbers plans to start sales in early 2017.
