Owners of the robot will need to regulate the values stored in the robot. Then it will confirm the task it’s going to take. Before the robot operates by itself, an owner must manually wheel it around the yard – 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 destroy your rose bush 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. 26. This article mainly talks about _________.回答正确答案是：A
