It's just a concept right now but I wanted others to see that the scale doesnt quite match. Right now its just stacked on there and neck is a little too long.

Thanks Bret and Irobot I actually didnt know that. I'm using a dremel with a cutting wheel. The dremel is a great all purpose tool for the "small" bots. I may need to buy some brackets instead of the stand-offs I originally was thinking of doing. They are too thin and will probably work loose with all the upper body weight. Im thinking of these to taper the top corner in. {I hate waiting for parts.}

Too bad you cant make your own brackets from thin sheet metal using cutting shears and a drill! Buy yourself tin snips and you will be making a lot more stuff! :) don't forget the file.

These are a bit stiffer than I could make.:)

In hindsight I should have posted a video of it before I took it apart.

Small update to the frame plan.

Although this shows 2 batteries I won't add the second one until later. It's for additional amp hours in a 12 volt system.

Thanks Dave.:) I'm waiting on more hardward fasteners, M4-ATX DC-DC power supply and a fuse block from the post office. The lower ABS sheet will hold the PS and charger. The upper will have the fuse block, power distribution block, an I2C bus, a couple small DC-DC converters, TrexJr motor controller and EZ-B. Maybe a signal terminal block though I'm not sure yet.

I have had a setback with my power supply I ordered. It didnt work and I sent it back. I should get it in the next 5 days.

The base frame shown above is complete.

I re-did the head with micro servos so I can fit hardware to change the neck articulation. I'm not 100% sure how I will do it yet.

I also fixed the waist with a new lazy susan that was suggested in the forum previously. Works like a charm.

I'm also waiting on hardware to stiffen the elbow joint with the direct drive servo.

I was thinking of using a chain gear arrangement to increase power and reduce range from 180 to 90 degrees however it will mean more cutting into the plastic and I dont want that just yet.

I know it isn't much but that's where I'm at. I need to hurry up because I will be job hunting in 6 months! Not fun.

Well that sux about the power supply (think about using the human "by product" from your Robots in the news article! :D Sorry to hear about the job hunting, but there is an upside..all those extra hours to build Pinhead ;) Thanks for the update
