Shape: The majority of the shape is a very low semi-circular
wedge that effectively means that any robot that tries to attack from
the front 180 degrees will effectively be going up the wedge. In addition
to this, the wide, rounded frontal surface of the wedge is more resistant
to spinners due to the lack of seams and the larger surface area. The
rear extrusion is primarily for balancing the robot during axe use.
Wheels: 4 very small (50mm diamater) cast aluminium
internal wheels on a simple skid steer - they are all housed within
the wedge part of the machine.
Motors: 2x S28-400 Magmotors at 24v
Turning circle: 0m
Armour: The frontal wedge is 7mm titanium with the
flipper having an extra 5mm polycarbonate over it. Behind the wedge
there is 30mm of titanium foam which serves to lodge weapons in it rather
than let them go straight through. The armour is mounted over a stainless
steel chassis with particularly thick bars running the length of the
robot and finishing either side of the flipper slot (inside of course)
to give a sturdier front, the area surrounding the axe mechanism is
5mm titanium (the axes plateau).
The rest of the armour (essentially the back and box section) is 25mm
HDPE as are the two 'sails' which are seen in the image. The sails serve
several purposes -primarily however they protect the axe mechanism from
crushers and other axes by making them unable to reach around the top of
it. They also aid in self righting in two ways- firstly they shield the
axe itself from the inpact of landing upside down, and secondly they allow
self righting to be smoother by allowing the robot to 'roll' back onto its
Ground clearance: The front 180 degrees of the
robot is effectively 0mm due to the wedge, the rear is upwards of 20mm.
Weapons: The primary weapon is the large pnuematic
axe on a similar mechanism to Terrorhurtz, running on a single canister of
CO2 at 250psi. The shaft is stainless steel and the blunt blade is 9kg
worth of hardox in the shape seen in the image. The benefit of this shape
is all the power of the axe is focused to a point so does more focused
damage, but the heavy weight and broad shape mean that the damage done is
heavy impact damage to shock the internals in a focused manner without
risking gettign lodged in an opponent.
The flipper is powered by 2 linear actuators with a relatively small
stroke and is inset into the body to keep is away from damage. The flipper
only lifts about 40cm so as not to interfere with the axe, but does so in
a quick enough motion that it can flip a robot over. The 'scraper' section
of the scoop if a further 3mm of titanium shaped into a forked shape -
this has two purposes, firstly for accomodating the axe. Secondly by going
to two points instead of a single hard edge it focuses the force of a
charge into a smaller area making it far more likely that the robot will
be able to punch under skirts due to the proportionally higher pressure
exerted and the much smaller points of resistance against it.
Strengths: Effective attack combination, fast, difficult
to counter, very manouverable.
Weaknesses: Comparativly weak pushing power.
