I have rather ambitious project I would like to share and get some advice on.
I am planning to build a scale model (Maybe 1:20 or 1:30) of this 600t yacht hoist. See photo
2 x independent wheel drive motors (May need 4)
8 x steering servos 180deg
4 x winch motors
8 x fall up position switches
2 x fall cable brake - for independent fall control during sling setup
2 x load cells
Remote control matching layout of the real thing - iPad if possible or I will build arduino controller
I think I will need 2 arduinos to run all this plus remote.
Master to receive commands from remote and drive wheel motors and steering servos
Slave to run winches, cable brakes and load cells.
I currently own 1 x MKR1000 and 1 x Leonardo so would like to use these. Or would I be better off buying a MKRZero or something else?
The real hoist is powered by a diesel engine driving 3 hydraulic pumps. I would like to program my model motors the behave in a similar way - bogging down if steering and driving with low revs.
I plan to make the structure out of water jet cut steel that I will TIG weld. Scale will be controlled by how small I can get the wheel units. Any recommendations for wheel/steering units?
