Is there a disadvantage of having different motors power different wheels?
Uh...my knowledge fails me here. I know that its bad, but I cant work out why exactly...
Not really a disadvantage Liam, but it might led to some dodgy handling
wats up guys can u check the stat of my new vapourbot pls and tell me wat u guys think
Name: Dark Destroyer
Shape: Old Storm (RW 1)
Colour: black
Speed: 24MPH
Weight: 220lb (100kg)
Armour: 6mm TI
Chassis: Titanium
Drive: 2 x LEM130 at 36v.
Power: 6 NiCad Battle Packs at 36v
Motivation: 2 TI Tracks w/ 1inch custom made raptor claw for grip
Ground Clearance: 0mm on the front 1mm on both sides and 1mm on back
Turning Circle: Zilch
Dimensions in CM (Length x Height x Wide) 75cm x65cm 20cm
Weaponry: crushing/lifting claw powered by a 2 Heavy Duty Motion (1000lb) Actuator (1 for the claw to grab opponents and the other to lift)
Self-Righter: invertible but can self right with weapon
Strengths: Powerful lifter, good armour and speed
Weakness: Hates spinners
I have no idea what a raptor claw is but apart from that the stats look ok.
Raptor claw - See Jurassic Park
Id change the name, there was already a Darke Destroyer in Robot Wars... You dont want to get confused with it:wink:
Ah, but how does that combine with tracks?
question; is there a disadvantage when say 4 motors power 6 wheels? (meaning 2 of the motors power 4 wheels with the other 2 powering only 2 wheels)
I dont think thered be one, to my knowledge, but its better to have all three wheels on a side being powered by two motors, in case you get lifted up. That way you still get full motor power from that side even if only one wheel touches the ground.
Im thinking it combines with the tracks by digging in as the tread rolls over the arena... I hope not because what Ive envisioned would be horrifically inefficient, and tear lumps out of the arena floor all the time:lame:
Turning would become impossible to.

Well, it works for raptors, why wouldnt it work for vapours? Raptors are pretty quick too :proud:
If you let you tracks dig in like that during a turn they would derail from the wheels.
Yes, but evolution did not intend raptors to be flipped around and hit with large spinning objects :proud:
(besides, I think they raised the claws off the ground when running, according to Walking With Dinosaurs anyway)

They must have done, because at the European Championships last year my raptor got hit with large spinning objects that flipped it around all over the arena :crazy:
...
Ill get my coat
Ive completely overhauled Werewolf, because it was unneccesary and boring.

Shape: Old Storm (RW 1)
Please remind me what Old Storm looked like?
It was an invertible box with a front that looked...melted. The only way I can really describe it, it was wedged but sort of not at the same time.
Can someone take a look at this, please? Im dont really know if its in weight.
Also, Im not knowledgeable about bore and ram and stuff, so itd be great if someone could help me out there.
http://strickenone.proboards99.com/index.cgi?action=display&board=danvapour&thread=30 1http://strickenone.proboards99.com/i...danvapour&thre ad=301
Not at all bad, the only thing I notice is that longer and shorter doesnt make much sense :P
For rams, I know zip about the sizes but I generally use 70mm bore as a benchmark for a decent flipper, going up to 100-110mm (or more if youre crazy) for a Gravity-style mega-flipper and about 50mm being the minimum to get any use out of. I may be wrong in my reasoning, but really at the end of the day its still a flipping thing, however technically you describe it :proud:
Uh... Longer and lower rather.
david here is a pic of old storm that i got from a Team Storms site my vapour is exactly the same coz my little brother wanted me to have a vapour just like old storm its he favorite robot here is the pic http://www.teamstorm.com/storm/gallery/storm.htmhttp://www.teamstorm.com/storm/gallery/storm.htm
The original Storm was a fun robot to watch. We bought its original hydraulic ram for a couple of years. Its gone now.

I seem to remember seeing the original Storm fighting The Dome once. It won, but The Dome did last longer than it did against Diotoir.
Heres my other stat can guys check it even the Dimensions coz im not sure if the Dimension are right
Name: The Grudge 1
Shape: Suicidal Tendencies
Colour: Black
Speed: 18MPH
Weight: 220lb (100kg)
Armour: 6mm TI
Chassis: Titanium
Drive: 2 x S28-400 Magmotors @24v
Power: Four 12v, 16Ah Hawkers
Motivation: Custom Made titanium tracks w/ 1 inch spikes for girp
Ground Clearance: 2mm
Turning Circle:0
Dimensions in CM: 1.38m x 0.74m x 0.70m
Weaponry: Pneumatic stinger powered by a 4€ bore, 12€™ stroke air cylinder at 200psi giving it about 2200 joules at end of swing
Self-Righter: The Stinger has a spike on top that pop out to self right the machine Strengths: Powerful weapon, good armour and speed
Weakness: exposed tracks from the back
You really shouldnt put spikes on tracks, it just negates the purpose of tracks, a lot of surface area. If you want to improve traction, use rubber strips on the tracklinks or use rubber tracks.
See Trax vs Storm 2 for details, Trax was just sliding all over the place.
ok but wat about the dimension are they ok
70cm high is quite high (2.3 feet)
so the Dimensions in CM should be 1.38m x 0.74m x 0.2.5m
Youre doing a good job Rurak. It took me any weeks to learn much, its taking you much less than that, a few pushes in the right direction will help.
In the mean time, can anyone analyse this, plus think of a better name for me please :lame:
F.P FLIP
€ WEIGHT: 100kg.
€ ARMOUR: 3.25mm Hardox monocoque on the front and 5mm Hardox monocoque for the rest, with 6mm Titanium on the base. Inside, 4cm of Vulkanised Rubber is on the front to protect it from shock-killing
€ SHAPE: A low wedge shape, with corners slanted to make the front more pointed.
€ MOTORS: 2 x LEM130€™s at 36V = 18HP
€ LOCOMOTION: 6 Vulkanised Wheels.
€ DIMENSIONS: (L) 100CM (H) 18CM-16CM (Gets lower) (W) 50CM-35CM (Gets narrower)
€ COLOUR: The body is black, with the name written in black on the silver flipper.
€ WEAPONRY: A C02 powered flipper made from 3.25mm Hardox, and powered a single 1000psi 70mm pneumatic ram, coming from 3 x 1.5kg bottles, giving 50 flips overall. The ram is geared at 4.4:1, so the flipper produces 800kg of force at the tips (can flip 100kg 4ft into the air), and when right underneath, the flipper has 1300kg of force (can flip 100kg 6ft into the air) To help in getting under skirts, a shallow Hardox wedge is added. The flipper can self-right F.P Flip in a 180* flip, but throws itself 1ft backwards and 1.5ft upwards.
€ SPEED: 20mph
€ GROUND CLEARANCE: 8mm all around, except for 0mm at the front, but it also has 6mm Titanium skirts held in place by 4mm Hardox skirts.
€ STRENGTH: Good armour and an awesome weapon.
€ WEAKNESS: Vulnerable to shock-killing from the sides.
Nitro-Gene 6.0 :proud:
What exactly is other peoples understanding of a moncoque? I assumed it meant that the entire robot is made of one fabrication that serves as the armour and the chassis, and this would rule out having different metals.
Im afriad Im not going to call it Nitro-Gene 6.0, and this is a CO2 flipper, not Nitrogen :proud:
And if you can check your forum, ca anyone tell me what they think of the FINAL edition of Nitro, as if 5.0 doesnt work, Ill just stick with 4.0.
By the way Joey, a monocoque is when you build a chassis and then mount the armour and electrics and various bits onto it, thus strengthening the design, so a 5mm Hardox monocoque is stronger than a robot with 5mm Hardox.

Its borderline still, Paul...Id switch it to 7mm titanium armour.
Its still very much overweight - as is the previous version, now I look at it, sorry.
Four LEMs
Hardox armour
Nitrogen flipper
One of these does not belong in a 100kg robot.
Incidentally, Paul, what you described - mounting everything to the chassis - is not what I would refer to as a monocoque, it is what I would refer to as building a robot :proud:. A monocoque would be if you welded the entire bodyshell and support brackets together, installed an access panel, and then mounted everything inside that with no frame.
(Message edited by joeychevron on June 12, 2008)
Okay, not borderline, QUITE overweight. :proud:
Scrap two of the LEMs, Paul. I dont know HOW many times weve tried to tell you that.

Actually Paul, that is exactly what is NOT a monocoque. A monocoque is a shell where the armour is the chassis, therefore saving weight.
quote:
Monocoque (French for single (mono) and shell (coque)) is a construction technique that supports structural load using an objects external skin. This stands in contrast with using an internal framework (or truss) that is then covered with a non-load-bearing skin. Monocoque construction was first widely used in aircraft, starting in the 1930s.
