7mm on top and bottom and 44mm on the sides.
Since that picture was taken i've added a extra bit of wood inside near the front to make it slightly stronger.

I know it would go against the whole idea ofthe plank reference but if you round the sides then ls4 won't rip ye to bits
it looks good though
don't forget to make spare pannels

Yeah I'll probably take a sander to it at some point to round it off a bit. There's a bit of a overlap on one of the sides I need to get rid of aswell.

Question: The 12v 3300mAh NiMh in Johnny 2x4 is quite new (Only 1 charge). Can I get away without discharging it and just charge it? I know it's getting a bit late to be asking these type of questions.

**Anttazz** · 13th April 2012, 14:20

You mean its partially discharged and you want to just charge it up again without fully discharging? That will be fine.

I wouldnt worry about small things like that at the Champs, if in doubt, ask and there will be loads of people around you who can steer you right.

And that's us packed and ready to go!
This will be my first event since Robot Wars so i'm looking forward to it!

DP:
A quick report about how Johnny 2x4 did at the UK Champs.

Short version: Badly, we got 3 points.

Long version: Match one was against Mini Mighty Mouse and Reavenger, my first time driving it in a place bigger than my kitchen and it worked well! It drove like a charm. However the lack of pushing power it had was clearly evident, got flipped my Mini Mighty Mouse and got beached on the side of the arena. 1 point.

Match two was against Ls4 and Ripoff, my plan was to go in and start pushing LS4 around before it could get up to speed, but Johnny 2x4, being 7.5kg, was too light and one small hit sent it far enough away to let LS4 get up to speed. Ls4 then drove into me, clipping the corner of Johnny 2x4 and sending him flying across the arena, killing the removeable link. 1 point. However Ls4 seemed to stop spinning so that was a bonus. I'm not sure if it was the arena or me that did it. One quick repair job later, which involved repairing the base and taping the battery back together and Johnny 2x4 was once again ready to run.

Match three lasted about 6 seconds, I drove at wedgie, wedgie then flipped me out, job done. 1 point.

We then entered various whiteboards, but Johnny 2x4 was limping, one of the wheels was at an angle, the frame was scraping along the floor and the battery was being held together by duct tape, along with everything else. It was a Class D insurance writeoff.

Basically, we did badly, but we had fun! People were friendly, matches were fun and the general consensus in Team Driving Force was that we'd sure as hell do it again. So that's all the matters. Right?

My plan is to make another wooden robot in the future, but before that, I have a plan for something made out of a more conventional material; metal.
