Mechanical Maelstrom Season 2.0
Gabriel IV posted on ZED, stats copied here:
Gabriel IV: Enjoy The Violence
WEIGHT: 100kgs
DIMENSIONS: 105 x 80 x 30 cm
SHAPE: Elongated triangular pyramid with steep rear and very shallow front
COLOUR: Yellow body, red, yellow and black striped flipper, black shapes on either side and shiny silver skirts and spikes.
DRIVE: 2 C40-300 Magmotors run at 36v from 6 NiMh packs, driving two rear aluminium wheels with urethane rubber treads for grip on the arena floor. The motors should survive at 36v due to a 300A current limit and the use of timing belts in the speed reduction, which should slip if the wheel locks up and therefore save the motor.
SPEED: 15mph average, up to 25mph max
TURNING CIRCLE: Zero (well, due to the wheels being at the back its not exactly zero, but it turns on the spot)
GROUND CLEARANCE: 0 at the very front point, rising to 14mm at the rear. Side and rear 3mm 2014 T6 aluminium skirts can be fitted giving 0 all around.
ARMOUR: The whole top and internal subframes are constructed from a 5mm titanium/vanadium alloy monocoque, which is double skinned in a few key areas like the nose for extra ramming and structural strength, with first line impact reducing 7mm welded HDPE armour over the top of that. The base is 3mm 2014 T6 aluminium with a 7mm polycarbonate layer on top, and is recessed somewhat into the bodyshell/chassis for added protection if flipped. The front nose has an additional layer of 2mm spring steel over it which is sprung down to the ground to get underneath other robots.
WEAPONS: A forward hinged pneumatic flipper of the same design as its predecessors, but modified somewhat; its powered by an 80mm custom built ram that can operate at up to 2400psi, the actual operating pressure being determined by what gas is connected and from there controlled from the transmitter by a variable regulator, so the flipper runs on anything from 250psi to full pressure CO2 (750-800psi) to, if the tournament rules and assorted conditions allow, full pressure nitrogen (2400psi). The standard gas supply is a 2kg bottle of CO2 giving around 10-15 uses at full pressure with more on low pressure. (If I use anything other than that, Ill state it on entry)
The front spikes either side of the nose pointing sideways have been made slightly smaller to not get in the way as much, are made from hardened tool steel, and should cause a fair bit of damage should I go into thwackbot mode.
SRIMECH: Via weapon. The back has spikes to prevent stranding, and because of the body shape it is very unlikely to do a Mute when self righting.
NOTES: Where possible, components are shock mounted to cut down on damage from spinner impacts.
STRENGTHS: Difficult to get a grip on due to the shape, low centre of gravity, extremely good weapon that shouldnt waste gas, quite powerful and generally very tough.
WEAKNESSES: People will look at it and assume they can damage it due to the lack of Hardox (for the record, Ti/10% vanadium alloy is almost equal to Hardox 400 in terms of tensile strength and hardness, and actually is better than it for impact strength, so...yeah. :P)
For this tourney, I might as well take advantage of the pneumatic rules...the flipper system will run off of a 2 kilo nitrogen bottle giving about 5-7 flips at full pressure, but Ill be regulating it down for just turning people over and self righting which should stretch it a bit further. For the first couple of flips though, if I get right underneath...bang, watch out for those windows.
