butler bot

 i have this idea for a butler bot. inspired by Norrislabs (BDS) beverage delivery system http://norrislabs.com/.  it will have 1 propeller board it will handle motion, the sensors and a slave for bat lvl temp snsor and controlling the peltier units. it wil have 2 window up/down motors with a h-bridge for each. it will be powered by 2 12v bats for the motion and a 7.2 bat for the prop boards and speakers. the whole thing should be about 4 ft tall.the fridge should hold 3 sodas depending on the size.

The Robot Builder's R-duino

June 24th, 2011.

I've been asked if I can make a board similar with the Robot Builder's Shield that also has the microcontroller on board and is compatible with regular Arduino shields. Not an easy task to do if I want to keep it with through hole components, but it's a challenge.

So I have designed a first prototype of the Robot Builder's Arduino R-duino. Features:

Workshop basics - working with templates

Just a quick entry to cover a point asked by Antonio about using templates.

I'll use an example of some leg components from a hexapod that I am working on currently. Here is how I made them to be accurate to each other, and also accurate to the design. I'll add pictures to this post when I get home.

The component is a joint between two servos, and is a complex shape - A circular section at the end of each joint with a curved centre brace between the two.

I will post a picture of it at some point, but it's essentially the middle leg joint of a bot like this:

Getting a Robot to Determine Its Own Truth

This piece describes an approach I am working on for an upgrade to SuperDroidBot “Anna” and a sharable brain service I am working on.  This is obviously only ONE approach to getting a robot to have a concept of truth.
