I bought a hanging scale from a fishing and camping shop. It can weigh up to 25kg.

I use three scales - a tiny 0 - 100g scale, a 0 - 2Kg scale (both cheapo from Jaycar) and a 0 - 20Kg scale off eBay for $116. The 20Kg scale is made by Jastek and has a resolution down to 5 grams so I don't need to fret about the bots being over the limit.

Those hanging spring scales are really handy, you can also use them to measure the tractive power of your bot to test wheel grip and weight distribution.

i see now, thx i will go back in and request this one!

Can anyone recommend a good cordless drill/driver? Decent quality not XU1/Ozito

I have been using dse 18v blue drills for years but my final one is now my backup drive motor so might as well get something a little higher quality. Thinking of just buying bunnings

I swear by Makita for my electric handtools. Never had one failing on me, except one old 10.8V battery, and even if it was 5 years old, it got replaced without cost. (I have to admit, I bought a new tool with the same batteries a month before).

In electric handtools, you get what you pay for.

I have the non-brushless version of the 18v drill, with the 3ah pack it damn near broke my wrist when i was drilling a 120mm hole in MDF with the adjustable hole saw when it got stuck.

The impact driver snaps the heads off 5/16th stainless steel coach bolts with ease ;->
http://www.milwaukeetools.com.au/power-tools/cordless/m18/show/m18cid-0 (180NM) with the impact you notice it a lot less it just goes bang bang bang pop and off comes the bolt head lol
(you can adjust the torque setting)
It does a better job of taking the wheel nuts off my car than dads TTI air powered impact wrench.

I got this one because there was a deal on them, about $400 I think for 2 batteries, charger, driver bit set, the drill and impact driver all in a bag from TTI.
