If by the flipper you mean Ceros, then it should be a heavy.

Glad to see you reviving Ceros, it was always one of my favorite UK bots. good luck getting it finished.

is there any 3.2mm hardox floating around, looking for ceros body armour panels. If not found a goos source of 4.5mm aluminium chequer plate which would do the trick that should keep out thors hammer !!!

also been trying to find out the density of hardox for weight calculation but cant seem to find it

[Eventorizon]

They don't give a desnity I run it as 8000kg/m^3. Its fractionally lighter but its always good to over estimate a fraction IMO.

[Mouldy]

when i use online weight calculators for pieces of material i just put stainless steel in as material... its very close on density and comes out right when i actually make what i designed in hardox.

looking for 3.2mm hardox 600x300 ish for the front flipper scoop

optipower lipo batts arrived and look great just spent an hour making the aluminium batt mount assembly, 3mm ali bent into u channel with mounting lugs, planning on using some sort of vibration mounting to the body silicone washers or rubber to help avoid shock. Still deciding on new gearbox design for ease of manufacturing as no longer have access to miller etc

Quick update battery box and mounting system complete mounted at top by springs and 6mm hdpe back allows flex and movement of the box but trapped within an outer frame to avoid coming loose just requires the foam sticking inside, battery fuse box assembly and new power cabling mounted and protected, armour mounts cut and 4mm aluminium plate ordered.

4mm aluminium is thin but all the weight I have left should bend and buckle under thors hammer but hopefully noy split as it should bend first.

gearbox design sorted just waiting on time to weld the mountings up.

test drive hopefully with full armour etc the next 4 weeks

Can the manual pressure relief valve be opened using a tool ie, t handle socket
struggling to find and easy access point for the valve handle without removing huge pieces of armour plating

Quick update Ceros back on track Roboteq had a full motor test today and it works !!!!!!!!!!!!!!!!!!!!!
No gearbox's fitted so not under load but its a start. Also today mounted new removable link, fuse box, battery assy, twin solenoid for burketts and tx in a box.

This sounds really good, is it hard bending the ally?

[adz600]

Bending ally is not too hard below 3mm just a good work bench some strong clamps, wood straight edge and a dead blow hammer to not mark the ally. 4mm I bent using a blow lamp to soften the material and bent on a skip front door as you require basic leverage to bend neatly as even a bolted down bench and clamps wont give enough grip at 4mm.

best tip small bends at a time and using heat gently in my opinion the slight property change due to heat will be minimal on most standard ally grades

[daveimi]

That's pretty cool, thanks for the advice

Hammering ally over the back step was getting harder towards 3-4mm so it's nice to know it's not just my weird methods lol. Like the idea of a blow lamp.

No, must be easy access with no tools.

9.5 Manual Isolation Valve
Gas cylinders charged to pressures of greater than 50psi must incorporate a manual isolation valve that can
be operated from outside of the robot.
9.6 Remote Isolation Valve
Where the manual isolation valve is not integral to the gas cylinder (for example: the gas is normally
released as soon as the cylinder is screwed into it’s mating pneumatic connection) must have an additional
remote isolation valve accessible from outside of the robot.
9.6.1 Position
Any remote isolation valve shall be positioned to minimize the pipe length between it and the cylinder.
This pipe length must fully vent before the cylinder is fully unscrewed from the pneumatic connection.

it only states manual release ie, not automatic but does not mention the use of tools
