Sorry to fudge up the seedings Richard, but I only enter things these days to make up numbers, and it looks like weve got enough people around to do that without my help.

Martijn, yes, it is optional.
Alex, do you think reducing Blizzards armour to 4mm aluminium boron carbide and some hole drilling would reduce the weight enough?
Frank, does this mean youre not entering? Sorry to hear that.

Able to save a space for a previous 3 times consecutive champ?
Ill be entering:
MDU 3
Rogue
Intensity
MOABIE
Infusion (new design)
The Ultimate Wedge (new design)
Sewer Snake (Real Robot)
Warrior SKF (Real Robot)
Ill have to work out my AW, FW, LW, MW tonight, but Ill be entering Gyrate Extreme in the SHWs.
Some stats up in the next post.
Mass Disctruction Ultimate 3
Motivation: Wheels
Speed: 12MPH (480MPH Tip Speed)
Weight: 100kg
Height: 250mm
Diameter: 800mm
Weapon: The robot itself is the weapon. It uses its drive and a custom made micro processor system similar to that used in a fellow translational spinner called Cyclone Bot to translate itself around the arena creating a €œVortex of Destruction€Â. Using 9 Hardox €œenlightened€ teeth, it tears its opponent to pieces when the teeth collide at a sub-sonic speed of 480MPH. Causing certain death to the opponent.
Drive: 3 x Briggs & Stratton Eteks running on 60v. The motors are protected with a current limiting circuit and a thermal protection system which will ensure the motors don€™t over heat. The drive system uses a unique variable drive system with load sensing technology which enables the robot to start rotating with a high gear ratio preset at 5:1 giving the motors high torque low speed. As the robot gains rpm, which is constantly monitored via wheel rpm sensors, the gearing then adjust to suit the load of the motors and gain further speed allowing the gear ratio to lower from 10:1 to as low as 1:1 at top speed. The gear ratio can also over drive thrown the ratio 1:2 giving the robot nearly double the original top speed and allowing far more energy, but this is only used when the opponent is at a distance where it can easily be disposed of. Otherwise, the drive is left at 1:1 maximum.
MDU 3 sports an advanced drive control system to that of Cyclone Bot as it uses motor and wheel sensors to travel and translate in the most efficient possible way, minimising energy lose. The drive will adjust ratio to suit condition if it is loaded and will change if need to translate at the full 14MPH (6MPH up on the last version since the robot size has decreased for faster movement, quicker spin up times and thicker armour). Spin up time is minimal and varies between 0.5sec spin up and 1sec when the system is suffering from battery voltage drop. At a mere 1/7th of its full RPM, this robot will be dangerous. 500rpm will have enough energy to throw robots out the road and allow it to continue it quest for domination. If people start ganging up on it (Everyone will, I know), the drive system will be locked down into 500rpm mode allowing the drive to have nearly maximum potential torque yields and it will force the opponents away till it can then safely power back up to full speed and deliver the force of the €œVortex of Destruction€Â. To ensure endurance during combat, everything has been shock mounted for maximum protection.
Batteries: 250 x 3600mAh NiCD cells producing 60v @ 18amps. The packs are protected by a system like the drive which give both current and temperature protection. The packs are re-enforced between the cells with Polypropylene cell holders and will prevent them from breaking during the impacts.
Armour: 4mm Hardox 500 with stainless steel welding built in a monocoque design with triangle shape and inner supportive bulkheads. 10mm Polycarbonate on the top to save weight due to the upgrade to Etek motors and higher voltage
Notes: Invertible. Soon to be your worst nightmare. All within your precious 100kg weight limit. Approche Avec prudence.
Mother of All Bricks Inevitably Evolved
Motivation: 4 Titanium wheels with urethane rubber and NIB magnets inside the rubber for extra traction on metal floors.
Speed: 15MPH
Weight: 100kg
Height: 220mm
Length: 650mm
Width: 620mm
Weapon: An active electric wedge, works both ways up and is primarily used to get under the opponent and allow the drive to show them the walls.
Drive: 2 x LEM200D motors producing around 52HP peak each when on there nominal 60v. The motors are current limited to 400amps, which limits the constant HP to 35HP combined. The motors will be run at 59.2 volts
Batteries: 16 x 3.7v 40000mAh Lithium Polymer cells producing 59.2 volts @ 40amps. The Lithium Polymer will give continous amperage of 5C(200amps) and peaks up to 10C (400amps)
Armour: 6mm Hardox 450 all over
Notes: Invertible
Rogue
Motivation: Wheeled
Speed: 18.84KMH (11.775MPH)
Weight: 91.39kg
Height: 248mm
Length: 523mm
Width: 1040mm
Ground Clearance: 10mm under disc teeth and increases to 20mm at the back.
Weapon: The weapon is a 24.61 kg, 580mm (From tooth tip to tooth tip) diameter flywheel mounted on a 20 degree angle. The flywheel is powered by a 6.8kg 125cc 5.3Kw (7.06HP) Husqvana chainsaw with modified Astroflight electric starter motor. The chainsaw has a peak RPM off 8500rpm and is geared 3.4:1 with a kevlar innerbound belt drive to produce a flywheel speed of 2500rpm. The chainsaw has a centrifugal clutch that prevents the flywheel from spinning at idle and prevents the chainsaw from stalling by cutting out at 500-600rpm. The weapon has a tip speed of 273.14Km/h while producing around 32Kjs of Kinetic Energy. The teeth are based on a shark tooth design where a inner concave to cut though metal much quicker and easier. The teeth are CNC machine blocks of Hardox 650 Wareplating to maintain a near perfect cutting edge.
Drive: The drive is a pair of S28-400 Magmotors coupled to a pair of 8:1 aluminium planetary gearbox which gives a final output speed of 500rpm at the drive shaft. The wheels are 200mm (8inch) Colson wheels with 3.25 mm Hardox 450 protection plates and 8mm thick Grade 5 Titanium/Vandium domes with tip spikes. The wheels are mounted on 40mm hollow, 5mm wall Stainless Steel shafts for maximum strength.
Batteries: 2 x 24v 3600mAh NiCD Battlepacks producing 24v @ 7200mAh supply (Enough for 10mins of solid driving, 8 mins of driving with several motor starts)
Monocoque (Chassis/Armour): The monocoque (chassis & armour combined) is a fully tig welded 8mm thick Grade 5 Titanium/Vandium with support braces and inner bulk heads for maximum strength and rigidness.
Electronics: Runs a RoboWars.org BMC speed controller with Hitec Focus SS-3 75mhz PCM 3ch Radio and a 3-axis computer Gyro for maxium control and handling. Uses 150amp rated Anderson power pole connectors and locking pins. Electronics are shock mounted and mounting in a floating style encased in HD (High Density) foam.
Notes: Can selfright via off balance weight distribution whe upside down and is added by the contact of the flywheel on the floor.
Gyrate Extreme (SHW)
Motivation: 4 x Omni wheels
Speed: 10MPH
Weight: 155kg
Height: 320mm
Length: 500mm
Width: 1500mm
Weapon: The weapon is the focus on the robots upgrade. The 45kg spinner bar/hoop combo is powered by two Honda CR125 Motorbike motors. The CR125 motor produces 42.3BHP @ 11500rpm, and only weights 14.8kg each. The motors have a pair of electric starts mounted on them. The weapon rotates at a crazy 4500rpm, via a variable belt drive that changes ratios from 10:1 through to the final 2.5:1 ratio. The variable belt drive works by the expansion of one pullie (Motor end) and the contraction of the other (Weapon end) This is done via torque springs mounted on the adjustable pullies and forces them to change size when the load changes. Commonly found on 6WD amphibious ATV€™s.
Drive: 4 x LEM 130€™s on 24v geared 10:1
Batteries:
Armour: Can you say 15mm Poly-Propylene?
Notes: The weapon is devastating. The power is phenomenal. The noise is incredible! The bot is not invertible€¦ Flip and gone€¦€¦ But you have got to get close to it to flip it!
Warrior SKF: http://www.buildersdb.com/botpics/2396.jpghttp://www.buildersdb.com/botpics/2396.jpg Team Whyachis 1000rpm Ring Spinner that powers the front flipper. Was able to launch Cyclonebot over 8ft into the air! The spinning rim is 2inch thick Cromemoly 4130 Steel!
Sewer Snake: http://www.buildersdb.com/botpics/374.jpghttp://www.buildersdb.com/botpics/374.jpg Ram bot with a front lifting wedge. Currently ranked #1 in the US and has beaten countless amounts of spinners, despite having exposed wheels.
Aaron, Gyrate is a bit overweight like Alexs Blizzard, so shall I reduce the armour by 1 or 2mm?
There are currently:
*5 places left in main comp
*1 place left in middleweight, lightweight and featherweight (that is, if AJ meant those when he said he wanted a place in all side events)
*2 places left in antweight and superheavyweight (again, assuming AJs entering these)
*3 people/6 robots needed to enter the Annihilator
(Message edited by velociraptor on October 08, 2005)
Yep, save me places in the otherweights too please. Im going to be away this weekend but I can start work on my bots by Monday if thats OK. :)
Alex, do you think reducing Blizzards armour to 4mm aluminium boron carbide and some hole drilling would reduce the weight enough?
Thats fine
Also Ill have archangel and baldur in the annihalator
Sorry Alex, but the robots you enter in the Annihilator have to be ones youve entered in the main comp.
