Auto Depth Plotting - Gumption Trap II

[@jacobmoffatt7318]

Have you looked into higher resolution options for the sonar to be able to map submerged objects? This is an awesome project that I can see having a lot of neat applications.

[@Clay-Builds]

That’d be pretty far out of my budget unfortunately. Maybe I’ll look into fancy side scans one day but for now this project is just scoped at rough topographical maps.

Excelente serviço, estou aprendendo muito com seus vídeos. esses sistema de escaneamento seria muito útil aqui na região, brasil. aqui há muitos rios com pedras, só quem é da região conhece, porem ainda ocorre muitos acidentes.

RTK gps?

[@Clay-Builds]

It’s not RTK, just a cheap neo-6m. Maybe I’ll experiment with higher accuracy in the future.

Cool boat. I like the low profile of it minimizing wind drag forces. I have some ideas you might want to consider. Since you have bidirectional running motors, it might be simpler to just use differential thrust for steering. Less components to break and easier to control if you only need thing to tune one thing. Also what kind of gps receiver do you use? You can imrpove the accuracy of your boat with a f9p rtk receiver and a ntrip service to a few centimeters level of precision. It will help with navigation too. Cheap gps recievers can have an error of 5meters and having you actual location jump around isnt helpful.

My first version of this boat used only differential thrust. I think the rudders are a more efficient way to make fine adjustments because it doesn’t need to constantly accelerate/decelerate the props, they just stay at a constant speed during the long straightaways. This gps is a cheap neo-6m, it doesn’t really jump around much. Precision is more important than accuracy for this.

@@Clay-Builds i agree that they are more efficient during straights but that shaft play must go 😆 but for 90 degree turns the diff thrust would be more effective. You could easily switch steering control if desired angle is larger than lets say 10 degrees either way. Also adding some type of fin keel on the hulls will help with horizontal drift.
