Help please

thanks for your replies, im learning lots. is is possible i could have some links for sourcing the parts required. i want to work out a rough guide on price.

A few things I have learned the hard way,

- Make sure you have adequate ground clearance to move in the arena. Its not smooth, it never is and you should never expect it to be. If it can run on the road outside your house then it is generally ok.

- Design the machine around the components and then make the armour, not the other way around.

- I would like to echo craigs point about padding batteries. It can reduce the shock loading by half if not more which is a very good thing if you are dealing with SLAs

- Aim for 95kg as you will go over. Far easier to a get an additional 500g out a heavyweight than 5.5kg (been there!)

Places for parts?

- second hand on here
- technobots
- HPC gears for all things locamotion
- RS for just about anything (but they are pricey)
- Robotmarketplace.com (american based so the delivery can be pricey)
- Maplins - those fidley little things like heatshrink and electrical tape that you always forget but make things so much easier

you got any hardox for sale gary?

[typhoon_driver]

I only have small sections in my garage at the moment and it will be a while before I get anymore.

What are you after?

[swanaldo]

looking for some 3.2mm..... fullsheet, whatever that size is looked on JL steel but they start at 4mm

[typhoon_driver]

nah dont have any 3.2mm im afraid and yeah JL only deal with 4mm.

These guys are one of the few if not the only in the UK that deal with 3.2mm

[typhoon_driver]

Lol then speak to the guys at that link that I posted or JL steel services http://www.jlsteel.co.uk/http://www.jlsteel.co.uk/

I have only dealt with JL as they are just up the road (30 miles) from me

Designing the robot is for me one of the best bits of the robot hobby. for St Hammer the idea was to make a robot the crowed would like, and one that was going to be reliable and capable of being run against other robots with different weapons. with out too much damage.
Below is a list of robot types and my thoughts on them.
Types of robot

Ram bot
St Hammer is able to run over the top of those types as they are generally low down

Hydraulic
I have armor fitted behind the wheels to protect against too much damage, I cant stop the wheels from getting punctured by KO. But when this has happened it has done no real damage to the robot and after the caws have released. the St Hammer just keeps on going
Tiberius I dont think Its claw can go that high to actually catch the robot! it would have to be raised to a hight of about 500mm or more!

Flipper
The idea is to make the robot able to drive off the wedge of the flipper and if you keep moving it makes it difficulty for them to get under to flip OOTA. in practice this is a lot harder than it sounds! With the shape of St hammer there is no upside down anyway.

Spinner
No spinners allowed at the moment, but i think it would be OK with most of them.

Axes
This area I have had little luck both Thor and Thz (The Tupperware Tomahawk) will give me problems, but i am working on a better amour solution for them.

Arena pit
It can clime out of the pit especially with the new wheels.

Bad driving
I have not been able to design out my bad driving skills but miracles can happen.

Its great fun to design a machine that can go against outer weapons and survive.
Be brave do something different but most of all enjoy the whole robot building and running thing.

Standard sheet made by SSAB is 6m*2.5m. This is the size that was ordered in 3.2mm a few years ago in the Netherlands.
Team RCC bought a few pieces of this plate.
