Another weekend over and more progress achieved.
This weekend I did amost a double shift on the robot build-
three hours Saturday and the usual four hours this Sunday.
On Saturday I worked mainly on the tongue of the robot
which will form the main buffer zone in case of a frontal attack
with the main aim of protecting the jaws from damage.
Adam who was unavailable this week had cut the tongue
plate in two last week and this plate needed further shaping before
fitting into the gob between the jaws.
I cut a bridge shape at the base of the tongue and this would allow
the chain and guides to pass underneath, I also added some sleeves
for the guides to enter and offer more protection against inpact.
The tongue was welded in place, guides and sleeves too and I was
well pleased with the finished effect.
On Sunday I continued where I left off and added the chains to the
guides and was once again happy with the operation, they turned out to
be really easy to pull with no guide wheels or grease and the way they
rattled in the scoop when pulled made a great noise.
It's been a bit of a brain teaser as to what will activate the chain
pulled scoop -gas comes with its own complications, like making space
for a gas bottle and ram and the alternative- actuators although strong, usually come
in a feeble aluminium casing and wont stand a major impact.
So my latest idea is to build our own strong enough actuator.
The rest of Sunday was spent strenghthening the scoop brackets
and fitting the underbody castors.
Purchase of the day was a weights bar and item laid around in the
workshop waiting to catch my eye and be fitted was a apprilia
chain.
