Yeah it is pretty cool..

 

hi bloody-orc, the drills already come with the gear reduction setup. I roughly spent $400 US on the whole project. Although come to think of it the cost of materials is $240; Wasted $160 in the electronics department developing the RF signals It was a huge step for me in the microcontroller field however.
I got those toothed cogs from my local bike shop. I had to get them ordered in for $9 US a piece. Thats ten there ($90!!!). To control it i made a RF transmitter. This is where most of the money drained away because i didn't follow the manchester coding required for the RF modules.

Lesson learnt- listen to nigel when he says 'use manchester coding!'
honestly though i kind of regret the project because the end product serves no practical use. It doesn't defuse bombs for law enforcement agencies, it doesn't destroy enemy terrorist radar systems, it's useless.

I was thinking of somehow remote controlling my lawn mower to stop my mum nagging me to do the lawn, or to do my home work blah blah blah... Or atleast make the chores more fun.

Pike would it be more useful if you had used tires??
i mean it probably slips a lot even when on concrete..
i'm sure you could devise some sort of rubber to grip the ground more.?..

 

So Pike, where did you get all this metal for the frames and everything? It sure beats wood and plastic.

A good place for metal online is www.onlinemetals.com

If I make a small robot I usually use diamond plate because it is cheap for 1/16
great price.

Also pike if you need assitance for a remote control lawn mower I can surely help you.

Eh Pike,
Just a thought for your tank mate, to improve the grip a heap better replace the chain with a toothed belt say off a car engine. It's easy to cut and join by splicing and contact cement seems to hold up pretty well. After looking at the tank I'm inspired enough to make 1 for me and my son. I do have a 7 channel R/C controller off an R/c plane so hopefully I won't have alot of trouble interfacing it. Then once I learn pic's a bit more replace the R/C controller and make it automonous.

Cheers Bryan

Unless the laws are different in Australia?, it's an offence to use an airplane R/C for a model other than an aircraft - for very good sensible reasons!.

local scrap yard has the right stuff when you come at the right time and at dirt cheap prices. I got 7.5 kgs of aluminium for $13 US (15lbs) but you have to come at the right time or they'll send it off to a great big smelter.

i was considering a composite rubber/steel bolts tread system but i ran out of time and just took the easy way out with press fit cogs, and bikes chains. I'll draw a diagram soon so you know what i mean.

nice tank pike,
i am trying to make one for myself
would you tell me where to fing a good design for the tank body model ?

 

Pike hasn't been here in years. The posts are from 2005
