Mr Basic - drive train too stiff for motors to move...

I just picked up a Mr Basic kit from one of those free shipping Chinese stores. It's gone together OK, but the drive train is really stiff and the motors can't move it (even on 6xAA NiMH). Any tips?

Mr. Basic Motor Driver Kit Problem

Hi, LMR!

I need some help with troubleshooting Mr. Basic Motor Driver board. Basically, I couldn't make it work. I use 4xAA Alkaline batteries [5.8V actual voltage] as power supply. MC Picaxe 18X. Relays are working fine, but Motors are not. With my little experience in electronics I guess BD681 does not open for some reason. But not sue, I might be wrong...

Mr. Suspense

Just starting a build blog for the Mr. Basic Challenge II.  When I get some more progress I will post pics and make a robot page.

I'm still developing ideas, but I liked Gareth's work on a suspension system for the original Mr. Basic Challenge, so I'm starting with that.  My suspension will use steel cable instead of polymorph for a flexible power transfer system.  Ultimately,I want to try a four wheel independent suspension, but I will start with the front axis being on one suspension platform and the rear on another.

LMR DAGU Contest rules anyone?

Oddbot mentioned in another post that some rules would/should be announced regarding the LMR DAGU Contest.

I thought the rules were vaguely outlined as something like:

1 Use the Mr.Basic kit.

2 make sure your robot is way cooler than the other contestants.

3 good luck.

-So, do we need any more rules? Do everybody have to use all the parts from the kit? Which partscannot me excluded? Is there an upper price limit?
