Starting Point

Re: Starting Point

Ok thanks for the advice . I may post this in the wanted section but is there anyone out there who could mill me some kinda gear box for my creation for around the £200 mark or is this way too little?

Kenny at ALK Engineering - look in the commercial section, or email him at kennyrobotics@hotmail.com - is the go-to guy for robot builders round here; he does top quality work for a pretty reasonable price.

Design something, draw it up accurately (CAD or otherwise), and have a word with him

Re: Starting Point

Im rubbish in CAD so going have to attempt to do it by hand I think, Not quite sure how to attach the axe to the final gear, wither to attach it directly to the side like I have done with the spocket, or whether to try and get something like this done. Before I put too much more thought into it does £200 sound about the right ball park?

Re: Starting Point

In the process of contacting kenny, had a first respone back but since that nothing for a while. Hopefully ive not put him off with my lack of design speaking of which anyone fancy designing it?

Re: Starting Point

Its been a while so I thought I'd update, I'm starting my first real job next monday so hopefully will have a bit more then my students pennies to spend. (Have also just moved to farnborough for my job, anyone in the area?)

No luck with the gearbox from kenny think he must still be making 180 ( which looks amazing).

So i thought I'd move onto another bit that I want to upgrade... batteries, think I want to go with some a123s how many would I need and in what configuration would I need to power a 24v scooter motor and two 18v drill motors. Also anyone making a suitable pack that I can buy lol. Also also recommendations for a suitable charger?

Finally I think farnborough college does night welding classes which I think might be useful so I can start to work with metal

As always thanks in advance

Re: Starting Point

thats what i did like 3 years ago before i did anything robot related i went and did a welding night course
not trying to give you bad habbits but on my earlier robots certain steel parts where 'borrowed' from there lol and i even got my lecturer to make the armour for my first ever robot TJ1 outta steel for me

so its worth seeing what u can get etc - cos they'll have loads of scrap they're not bothered about

Re: Starting Point

Cool think I might just have to do that then, do you know anyone on the forum making a123 packs?

Re: Starting Point

Okay so I think im going to try build my own packs, Im looking at 7s2p packs of the 2300mah cells. There going to need to power a electric scooter motor and 2 drill motor. Will this be enough to power it for a 3 min fight or is it overkill?

Re: Starting Point

Actually have just been on the A123 systems website and seen they are releasing a bigger cell. Which might mean I can just use a 1p pack

A few details can be found [ur=http://www.greencarcongress.com/2008...fil.htmll]here

Re: Starting Point

Been working on a design for my gearbox and base for a while now and thanks to alex have a sketch of it in cad.



The base on the image aint full size but to give you an idea of size the bulkheads are going to be 250x100x10mm and the base 350x400x?mm

What do people think and how thick do you recon the base should be?
