So, there have been many boats attempted, and a few have turned out nice. However, I would really love to have boats that work well on a larger scale. Is there any possibility of this happening?
Also, I have a foolish idea. So, the limitations, overall, boil down to the problem of the boat floating like a bot, but moving like a vehicle. So why not create a bot and a vehicle, and control the vehicle from the bot and vice versa, allowing the vehicle to do tilting and steering and such, while the bot does the floating? I don't have any idea if this is possible, but couldn't you just set the velocity of each to be the same, and all that?
