A father decided to build a drone helicopter to follow his child to the bus stop rather than walking him there in person.
“Last winter, I fantasized about sitting at my computer while a camera-equipped drone followed him overhead.” That is the revelation of a father who provides a detailed account of building an Arduino-based gyrocopter that could follow his son, in grade school, who he normally walks 400 meters down a hill to the bus stop each morning. He chose a quadcopter design for its maneuverability and ability to hover. He did not buy a kit but instead got his parts separate. His project involved a central frame to hold the electronics, aluminum to support motors and propellers, and legs to cushion landings, a main control board and sensors, batteries, power distribution board, power controllers for the motors, radio receiver for standard remote-control flying, and an RF modem for computerized control.
