BRRRRR-it's been a raw day with a freezing wind but the build continues.
First task was to test the drive system via the speed controller to see
if the wheel spin problem is better with a gradual power increase,
So we set too wiring up the motors and the speed controller and the
radio control-this seemed to take quite a while, I think mainly because
the wiring circuit is not so much plug and play its more screw,zip ties
and gaffa tape-but we are working on the correct wires and connections
for this and the final version should take 5 or 10 minytes tops to
connect.
Anyroad we tried the Robot with the RC gear and although it managed
to bust the door again the performance was sluggish and some wheel spin
still occured so reluctantly we need to modify the gear ratio.
After removing the speed controller we began work on a idler sprocket with
a 2 to 1 ratio, this was in the form of a stub axle type shaft supporting
a couple of sprockets on a brass bush-fabrication went really well until
I realised that the axle shaft had been made too short and didn't allow
for the second smaller sprocket-this was a real set back but after I had
taken Adam to the bus stop I was able to rectify the mistake and I'm
just awaiting sprocket size confirmation to finish the lathe work.
