firstly this is my new name, i have started a company and wanted this to reflect my user.

Arent you being a bit harsh on Gary here?
leo you dont know the full story.
If it is only a drive problem that should be easy to fix.
i wish it was that simple.

If anyone wishes to take on the task of fixing the current drive train I am happy to advise where the problems currently are and how to fix them.
and who is going to pay for it gary?

Logistically speaking it is impractical for me to take on the task
but it was ok logistically to take on the task? i even offered to PAY to post the items to you but thought you should pay the return postage once repaired.

i was never looking for a service contract, just a working robot and drive system. all that was asked was the robot could run on smooth tarmac/smooth school floors without damaging it.
we tested it for the first time the other day on a smooth school carpet, the robot struggled to move, the wheels were spinning and not gripping the floor, then we noticed the threaded rods used on the drive (pic to follow on profile later) were bent like a banana so we stopped it.

fair enough gary you did give me some pointers to fix the problem and after hours of trying was getting nowhere. i then wanted to send you the faulty parts to repair to which you replied sold as seen, no warranty which is very disapointing to here from a friend.
you have also now pointed out that comprimizes had to be made in the build (hence not using gearboxes for drive) which to me means corners had to be cut to get it in budget. i gave you an extra 4 weeks for the project and you only tested the drive days before i came and openly told me of last minute problems your garage wasnt a safe place to test the drive and as a friend i trusted you when you said it was fine.

it is a shame as the rest of the robot is great, the arms moving etc.... but what use is it if it doesnt drive, i would of thought the first thing to sort was drive. i would rather have an active drive and no weapon, than a active weapon and no drive.
