When it comes to maintaining a dam, there’s more to worry about than stopping the walls from falling down. Silt buildup can damage a dam’s ability to effectively collect water, which means they need to be scanned and dredged periodically.
Yamaha has developed an autonomous boat designed to make the mundane task of dam and lake bed sediment surveying a little bit easier.
Yamaha’s Breeze10 uses a satellite positioning system in combination with azimuth angle data for autonomous navigation, with routes able to be saved for use again when resurveying.
Measuring 3.2 m (10.4 ft) long with a beam of 1.2 m (3.9 ft), the craft is compact enough to fit in a large minivan and can carry sonar, such as R2Sonic’s “Sonic2024” narrow multibeam sonar system, for scanning lake and dam beds.
