Time for a few early photos,
Guessing its around 60 percent complete.
First a revision of the drive train, same gears as b4 but made more modular and easier to work with. Bought 2 new motors yesterday to increase its speed rather than adding cells.
Think will just run this at 14.4 volts. New motors have about 15-10 % less torque but have almost twice the power – don’t really understand that , Anyways the key thing is new motors increase speed by about 65 %.
Heres some pics of the new steup – I like to call the poor mans Dewalt.
Setup in photos is only a 9:1 gear reduction, when u add the angle grinders end up with about 24:1.
@Gary, photo shows the gear and ouptput shaft that have to connect. Will wait and see what u have dug up, have also found a few bits to try but they require the Russian building technique –( smash it with a hammer) so will be patient till the weekend.

And here Is an early preview to how the new bot is looking, you can see the resemblence to poochy. The body u see is actually 2 parts. The outer shell is connected only to the drive bulkhead and abslolutely nothing is attached to the armour.

One weird side effect is the armour acts like a bell, when hit it resonates for ages and depending on where you hit it it changes the frequency, don’t know yet if this is good or bad.
Finally the wheels, I just dig them, have dropped robot a few times and it just bounces off the wheels very noice. The inner parts of the wheels have already been slashed so they have some give if someone tries to rip them off. Depending on weight will try to add some sort of armour but shall see. _________________ Bots that do not destroy you, only make you stronger.
