Using the HerbF® golf course lawnmowing robot to pass down veteranskills in golf course maintenance
Demonstration of fully automated lawnmower on September 24 (Fri)
Hasegawa Laboratory of Shibaura Institute of Technology, Seibu Construction Co., Ltd. and MIRAIT
Corporation concluded a memorandum of understanding on mutual cooperation for joint research anddevelopment of the HerbF® system for robotization of existing golf course lawnmowers on Tuesday,
September 07, 2021. This R&D is for robotization of existing lawnmowers in operation using the“teaching playback method” reproducing the actions of a veteran greenkeeper with the aim of unmannedlawn mowing. This demonstration of automated lawnmowing will be carried out because it has currently
almost reached the level of unmanned testing.
In recent years, there have been concerns at golf courses about a crisis of succession of skills ofveteran greenkeepers, the increased workload of greenkeepers and the deterioration of the working
environment due to the increasingly serious labor shortage. In order to resolve these issues, byrobotizing existing equipment, HerbF® will support golf course maintenance where there are concerns
about a shortage of skills and a labor shortage to maintain quality. Productivity of lawnmowing in golfcourse maintenance is also expected to increase by operating HerbF® during idle time such as at night.
The roles of each of the parties in the demonstration are as follows: Shibaura Institute of Technology
will conduct research and development of HerbF® (general programming such as autonomous runningand LiDAR control), Seibu Construction Co., Ltd. will manufacture and adjust the apparatus for attachingHerbF®, and MIRAIT Corporation will provide 5G communications technology and testing sites, advice
from veteran greenkeepers and existing lawnmower equipment.
As the system has presently almost reached the level of unmanned testing, a demonstration of
automated lawnmowing using the teaching playback method of the HerbF® system for robotization ofexisting golf course lawnmowers will be conducted at the Musashigaoka Golf Course (Hanno-shi,Saitama) from 1pm until 5pm on Friday, September 24, 2021.
Going forward, the three parties intend to consider prototype development and commercialization in2023 based on the data obtained in the demonstration.
