Cereal Box Killer Update

[team_penetrator]

Hi, our first middleweight robot Cereal Box Killer is being built ahead of scedule. The chassis has been built and we are currenty trying to get the right componants for the robot. I have been in contact with Team Onslaught and may be taking a trip down there soon to have a look at some motor and stuff. The disc in nearly completed, it weights about 12 kg at the moment without weight reducion holes.
The robot will hopefully be ready for its first battle with Blazer at RAF Cosford on the 13th of June.

Cereal Box Killer Update

good news, any pics? Not done anything on blazer for a while due to getting the other robots running. Waiting for a few bits to be sorted. Blazers specs;

2x 400watt (ish) wheelchair motors
2x 7Ah SLA batts
2x Curtis speedos
Pneumatics consist of a 80mm bore 210mm stroke ram at 10 bar (about 500kg of force), 3/8th high flow valve. 12mm tube, at least one 1litre buffer and maybe twin regulators (depends on weight). Armour will be whatever weights left :P Hopefully get some pics up on the website tomorrow.

Im weighing up components for the new machine.

chassis
motors, gearboxes and wheels
batteries
ram
extinguisher (estimated)
pneumatic valve

Just a tad over 30 kg. That sounds OK to me, but plenty of work to be done. Ive got lots of ali checkerplate and polycarbonate.

Anyone else aiming for Manchester in August?

yup

Blazer look like similar specs to me. My motors are smaller but running at 36v. My ram is 80mm but finding room for a buffer tank seems too much for me.

Be wary of having too little armour. Its a melee so you might be after someone and get a spinner suppository that you werent expecting. Its rather different than one-on-one.

Alan,

Are you using the wheelchair gearboxes? I am but the wheels are rather large at 12 or so. Johns Steel Sandwich is a masterpiece of minaturisation that means that he has the weight left to have battleship armour, just right for melees.

I think that the buffer tank negates the need for a second regulator. I think that Ill have to see if I have room and weight for a buffer too. I might even be tempted to fit a spare valve in the circuit as that might prove a bottleneck in my setup.

My ram is 160 mm and is bloody awkward because of the length. You must have it even worse. Im thinking perhaps that Ill have the ram fixed and sitting in the bottom of the chassis. How are you doing it?

Ive never used pneumatics before. what sort of experience do you have?

ive had enough experience in melles with the feathers and heavy. Im going to concentrate the armour on sides/back and just keep thin stuff on base/top. Us flippers will have to stick up for each other, get rid of those nasty spinners!

the last post appeared whilst i was typing the above :P we have a fair bit of experience with pneumatics. We started of with the feathers, in G2/G3 we started with a compressor flipper over a year ago, then it got changed to Co2, It now uses a 63mm bore ram and is probably the most powerful LP flipper on the circuit. The heavyweight uses a FP system.

Ive overcome the ram problem by having it at a awkward angle, but due to the power it overcomes this. Due to the size of ram it really has to have a buffer, the twin regulators was just going to help with filling the buffers up quick. I dont know many regs that can fill a 80x210mm ram quick enough.

I am using the gearboxes on the motors, they have been slightly altered but still need the 12inch wheels (which makes the robot look rather odd!). My chassis is mainly made from 1mm wall 25mm steel box, with 2mm thick used on the flipper.

That gives me some pointers. I am still thinking about the idea of a fixed ram and an arm.

I may well have room for the buffer tank as the wheels are going to produce a rather humped back effect.

What hinges are you using for the flipper?

The bodywork is a fairly monocoque affair having got a perforated stainless steel box as scrap. the idea will be to weld this up and clad the outside with checkerplate ali and/or polycarbonate.

im making my own hinge, similar to the one on Merlin. We had alot of problems with Merlin breaking hinges. All it will be is a steel tube with a stainless steel bar through.

Phots are on the website, http://www.blazerbotics.co.ukwww.blazerbotics.co.uk under blazer

Alan,

Im currently building a feather flipper and planning to power it with a compressor - could you please let me know how you attached the compressor into the pneumo system as this is currently my main grey area.

Cheers

Kev,

We took the compressor hose off and just fit some 6mm pipe onto it with a jubilee clip. It works ok as long as the compressor doesnt get too hot and soften the pipe. Works well as a overheating safety device

sorry, no pics yet but will post them on my site when i get some.

thats all we did.

OK Cheers for that - Did you cut the hose or take the compressor apart and disconnect it? It would be nice to still be able to use it as a compressor if I suddenly found myself en-route to an event with a flat tyre
