Let's Make Robots!

Scaling down a boat to make USV

I have been dealing with asects of theis for a while and this is my latest idea. Build a small plywood boat downsized to be a platform for robotics testing. I bought a "partially built kit" on eBay that turned out to be an abandoned upgrade of a hobby grade boat. It's a 15" V narrow plastic V-Hull and I am concerned about it being to close to max with a decent battery and gear in it. But the upgrade in process inculded a good servo steered rudder and through hull prop hardware. The supplied motor is marginal but workable. I have a brushed ESC with 5v BEC.

MY AGV development platform

 

I decided to do this as a blog as I plan for this to be a long term test platform as I mess around with different tech along the way.

OK I started by buying this RC truck chassis on eBay:

It uses a 7.2v NiMH battery and powers the motor using an ESC that delivers a few AMPs of 6v through a BEC to power a transceiver and the steering servo. Instead of a transceiver, I am hooking up an Arduino Fio and various components, housing them in a project box:
