A demonstration experiment of ultra-remote construction of heavy machinery using a multi-link communications system was conducted at an actual dam.​

Taisei Corporation is developing construction technology that enables remote and automated operation of construction machinery to counter dam sedimentation. The photos show a demonstration experiment of ultra-remote control construction and an on-site briefing session.​The briefing session was held in the control room and on-site, with a total of approximately 25 people attending.

In this demonstration, ultra-remote construction was carried out using a backhoe and crawler dump truck at Shimokubo Dam, approximately 90 km from the control room, via a multi-link communications system. Satellite links were used as the communications backbone at the construction site, demonstrating that remote construction is possible even at dam sites where mobile phone lines do not reach.​
