YouTuber builds automatic laser-powered lawn mower

YouTuber rctestflight built an automatic laser-powered lawnmower using Arduino microcontrollers and a high-powered laser.

has released a video of his experiments with high-power lasers to build an automatic lawnmower.His build comprises a 40W blue laser from a computer numerical control (CNC) cutting machine, a 3D-printed motorised gimbal for rotation, and an old camera lens to focus the beam.

While the homemade grass-cutting gadget is impressive, it could only clear a few feet of grass over a week.To improve the laser’s performance, rctestflight replaced the 40W blue laser with a high-powered laser array consisting of 24 smaller diodes.However, while its performance improved to approximately six to eight feet over a week, the process was still agonisingly slow.

His build comprises a 40W blue laser from a computer numerical control (CNC) cutting machine, a 3D-printed motorised gimbal for rotation, and an old camera lens to focus the beam. While the homemade grass-cutting gadget is impressive, it could only clear a few feet of grass over a week. “The breakdown of a generation unit at Arnot, Duvha, Kendal, Medupi and Tutuka power stations, as well as the delays in returning to service a unit to service at Hendrina Power Station, have exacerbated the capacity constraints,” Eskom said. To improve the laser’s performance, rctestflight replaced the 40W blue laser with a high-powered laser array consisting of 24 smaller diodes. Mzi Deliwe, deputy CEO at Provantage Media Group said airports have recovered with greatly increased passenger numbers as well as more interest from advertisers for airport advertising space. However, while its performance improved to approximately six to eight feet over a week, the process was still agonisingly slow. The process to return the unit to service is underway, Eskom said. The YouTuber tried to improve the design further with a 3D-printed vacuum powered by a 2,700kV brushless motor to pull the blades of grass upright for faster cutting. SA is a sought-after global destination and local airports are expecting increased passenger volumes over the December holiday season.

However, the vacuum was way too loud. At the time of its statement, Eskom had 16,142MW of generating capacity unavailable due to breakdowns and 4,588MW out on planned maintenance. Smaller airports such as George have benefited from the work-from-home trend, with more people moving out of large cities to smaller towns. Rctestflight mounted the laser cutter to an automated remote-controlled vehicle that travelled around two meters a day — or 0.00016 kilometres per hour. He used two Arduino microcontrollers to control the movement of the laser and the mower’s speed.
