The
past couple of weeks have been pretty frantic to say the least.
We have been working hard to get everything ready for Robots@War
and we just about made it. Overall BP now is clad in armour and
operational, but not entirely finished. For one thing, we have not
been able to get the interfaces for the speed controllers in time,
so we are still using the old servo-pot setup from Panda Monium.
It still works impressively well actually.
The
bot is covered in at least two sheets of armour (polycarbonate and
aluminium) and the sides have three layers of polycarb. The drive
has been giving us no end of problems. It will not stick to the
axles properly. We have tried everything and it just isn't working.
We knew this would be a problem but we want to see how we got on
in the fight anyway. We fought a robot called M2 (see the Robots@War
3 page for more info) and got some good blows in on target. The
axe performed well except the blade. As can be seen below, after
the first hit it started to bend. M2 had a sheet of 10mm polycarb
on the top and it was this we hit.
We
did penetrate part of the way through, but there just wasn't enough
weight behind the axehead to keep up the inertia. After a few blows
we ended up with this nice scrolly effect.
We also found
that the regulator in the pneumatics kept freezing up. This was
a problem towards the end of the fight (it gradually got worse).
The other problem
we had was the drive (as suspected). After a few attacks it started
slipping and the mobility gradually got worse and worse. At least
we know what the problem is with this and we have some ideas of
how to fix it before the Robots@War Arena contest in two weeks time.
Aside
from these hiccups, BP did pretty well. It survived to the end of
the fight and the axe mechanism was all up to scratch. We had one
minor bodywork scratch but this was down to us not fixing one bit
on properly rather than a design fault. We also suffered from a
bend to the rear chassis member but this is because the wheel guards
are not in place yet and so there is nothing attached to it at the
moment.
The general
driveability of the bot is much better than last year - either my
driving is getting better or the lower height has improved stability.
Hopefully this will improve even further when we install the new
Team Delta interfaces shortly.
We
had some additional team members for the day as well. Here you can
see Steve's daughter and my baby daughter making use of the extensive
leisure facilities BP now has on-board. Shortly we'll be adding
a leather drivers chair, a drinks machine and air conditioning...actually
its already got that when the ram vents!!
You will notice
also the chain. This is our safety restraint (which Derek Foxwell
has cleared) and we have the single pull-out switch fitted at the
rear, together with the gas vent.
