Hard Time's build diary

My robot is 2-wheel drive, so I'm getting 2 wheels with nut inert and 2 without.
I'm using these motors http://www.homebase.co.uk/webapp/wcs/st ... 7C16849334

so are you running the other 2 wheels via a belt drive from the motors?? or are they just dead wheels ???

They're not driven by belts, they're free spinning. Bodge job came yester day and I needed some bearings. I saw his scooter and thought 'hmmm' , so I took my 10 quid scooter apart and in each of the wheels were 2 bearings.That is a cheap way to getwhaeels and bearings. But, I'm not using that way as the bearings are to big for the blue wheels.

Mounted the motors into the plastic assembling it tomorow

My robot so far, in bits.[attachment=0:2whijhdy]Big 'n' Scary, Like a LASER.docx[/attachment:2whijhdy]

Ordered bearings and steel bar from technobots last night.
These are the bearings: http://www.technobotsonline.com/miniatu ... x24x6.html

I need a 12v battery that can power 2 drive motors and a lifter motor I'm thinking of using this battery: http://www.technobotsonline.com/haze-hz ... 2.2ah.html
Is it the right battery? If it is'nt what kind of battery is better?

That's a sealed lead acid battery. Usable but somewhat under powered. SLAs were used around 4 or 5 years ago in featherweights and were the standard at the time.

I'd recommend looking at nimh batteries instead. Something like this pack here,

Will give you all the power you need for your 3 drill motors. I have used these packs in the past and they have been fine.

Bearings and shaft came last week. Got a bench drill over the weekend adn going to drill the holes for the bearings to fit into

Sabertooth 2x25a came today, hopefully over the weekend assemling the robot.

my robot is now fully built and running. I'm using a lesd acid at the moment, but would battery be good(it is shown in a set but i would buy the battery on its own:
