Let's Make Robots!

presentation anxiety

I used to work as a techy in theatre, and loved the part where a artist would come to us with a vision or idea, and we had to transform it into actual stuff. They would come in and say "and in the end she is eaten by a dragon" And we'd set about making an exitpoint on stage with lots of fake fangs and fire and smoke, a couple of lamps indicating dragon eyes and scary noises over the speakers.

Well, I've stopped doing that now, but picked up a hobby along the way: robots.

Zen Master

I'm building a robot with many different voltages here.

I have managed to avoid voltage regulation by cheating, I run the motors that are rated for 4.5 volts at 6 volts from a RC NiCd battery, and I use an RC Electronic Speed Controller that can give 5 volts to the RC receiver, the wireless camera and the Picaxe. I feared that this might be a problem and turned to the all knowing LMR forums for help. And help I got...

So, I've been to London, UK.

The entire department at work went there for "seminar" which means we did two 30 minutes meetings, And spent the rest of 3 days shopping, sightseeing, going to concerts and other touristing...

Our plane back was delayed and the bunch of us spent the time talking about what we'd done. Some had bought shoes and clothes, one girl had bought jewelery, one had bought records, and so on..

What about yourself? -someone asked me:

Basic progress

Here are a map of parts in the Mr. Basic kit

Mr.Basic manual page 3
So far I've dicharded:
The wheels (13&14)
The bumper (17)
The battery holder (18)
The front axle shift metal fixer (20)

and I've mutilated/hacksawed/drilled:
an Axis joint device (5)
both Front axles(7)
The Chasis (11)
one Decelerated pinion chassis (12)

And I know some of the copper tubes (22&23&24) have a dark future ahead dating my trusted hacksaw.

ROV parts

I'll do some research into building a ROV.

I'll start by finding nearby vendors and usefull online tips. 

Since I  live in Norway many of the links posted here will be worthless for anybody but myself, but then again, this is my blog, why should I care?

Mr. Shortage. Water Shortage

I've spent a lot of time trying to get a reasonable function out of a water spraying mechanism that could fit inside the small frame of Mr. Basic, but the only solution has been keeping the water it a bottle in avertical position. This has made Mr. Basic very prone to tilt over and land on his side during creative maneuvering. So today I saw a cheap pea-shooter with 1000 plastic pellets for $11 in a store, and it looks like Mr. Cat Squirter Now is becomming Mr. Violent.

Now if only I could get these wheels to work with the Mr. Basic original drive train.

My StartHere references

For future reference, and my own convinience, I'm posting all the links that are nice to have available when trying to make a StartHere-bot with a SRF05 quickly.

OK. Fine! You won. Big deal...

All my projects has been mechanical excercises and/or remote controlled thingys.

And after I posted my first biped here I recieved messages like "It needs a micro controller!" For that reason I've refrained from posting any of my other projects...

I even posted a rant on the forum about that robots might be robots even though they dont have brains.

If anybody would donate some small plastic gears for my toy competition entry, feel free to contact me, OK
