hi
robot is going well :mrgreen: just the weapon
what is a lowish flipper psi rating ????????????
Theo
It normally goes on Bar... I would say 8-10 Bar is ok
Hi
thx for the info
my weapon is going to be 10 bars
how much would a co2 tank from the
peeps from nottingham??
be best if you got a 600g co2 bottle, johno sells them for about 40ish i think can't quite remember
I no but he told me to get them from
the Nottingham people
and yes I am using a 600g (20 oz) bottle
theo
how do u control a 5/2 valve with a rc controller???
like...
http://www.technobotsonline.com/aircomp ... 32670.html
(how many bars can that hold)
theo
8 bar ..you'll need a r/c switch
http://www.technobots.co.uk/acatalog/Sh ... s_157.html
any of the first 3 will do.
Thx that's proberly all
theo
I am going to buy this 1
http://www.technobots.co.uk/acatalog/Sh ... A_670.html
But how do u attach the valve to the mirco controller
Theo
Be aware Theo that that is infact the old website
Try www.technobotsonline.com ... He may not do some of the robot based stuff anymore
http://www.technobots.co.uk/acatalog/Sh ... A_670.html
Simply replace the motor in the drawing with your valve solenoid.
That's assuming you can buy this switch from the new site.
what drawing :? .......
o i found it :rofl:
and yes they do still sell them
do u have a pic of a inside of a robot with 1 like that with a speed controller
(because i dont understand how u put the battery wire to the speed controller and battle swich)
Theo
made a mircosoft thingy
Here's a std type pneumatic diagram.

So would my 1 work
But how do u split the battery (1 to the speed controller and 1 to the battle swich
or do u do something different
theo
Lets start with a simple battery , motor and dual speed controller setup.
NOTE that the receiver is usually powered from the speed controllers BEC.

Questions?
No prob with that but how do u give power to the esc and the weapon
because the pic that was on tecnobots said that the battle switch (for the flipper) needed
to be conected to the battery
Theo
an inside of my robot
The supply to the Battleswitch (for your weapon) and the supply for your ESC are wired in parallel... so after the safety link you would have two red (positive) wires, one goes to the ESC and one goes to the Battleswitch. Then two black wires from the negative side of the battery, one to supply the ESC another to the switch.
(BTW, please can you just use basic .jpg images? I have no idea what a .pptx file is nor can my computer open them)
more pics

(u should make a pneumatic guild and get a sticky) :D

Thx again just need to buy all the stuff and finsh my frame and get a vid on utube
Theo
Having read through this thread I have one comment on you building a pneumatic flipper, do your research!! Firstly if it's planned well it will be quite cheap and you wont buy stuff you don't need, secondly if you take the time to understand how the pneumatics systems work then you're less likely to get your arm ripped off by your nice new flipper.Quote:

Woody has some really useful information and you can always turn up to an event (Like Portsmouth or Maidstone) and get someone to run you through how things go together.

Firstly I have go to an event and asked
and I have had 3 month of reseach just on the weapon ok
and I am not a dumb 10 year old kid 8)
I know what u r saying and I do know safety is no.1 when
using a cut or welder
Theo
Hi
just going of pneumatics for abit.
I have 2 14.4v motors(and gears) and I was woundering
do I need 2 batterys in 2 parallel or 2 in series or just 1 battery
:talker:
Theo
in series, and you could either get 2 x 7.2 volt packs but if your using drills i'd recommend over volting them with 2 x 8.4 volt packs for more speed
well i am using the drill packs (yes i know the rubbish (1300mah)
but i cant buy some(well i could get my dad buy them)
so...
EIDT: I have 2 14.4v batterys
Theo
Wire them in parallel. That'll give you 14.4V and 2600mAh which will provide a more respectable running time. If you wired them in series you would get 28.8V, which is fine, but you would still only have 1300mAh and several speed controllers suitable for featherweights don't operate up to 28.8V
my dad said series (but i didnt think that would work and blow my esc)
so thats done :proud:
i will get a frame pic when its done lol
Theo
P.S thx for the quick reply 8)
BIG NEWS
I HAVE THE NAME FOR MY ROBOT
(copyright now apliy :rofl: )
MY GREAT NAME IS................................................ ....
NINJA (warrior, stom, Thunder, ect...)
Theo
P.S is this name used yet
Paint it yellow and call it Happy the littlest robot
thank!!!!! :angry:
:rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl:
errrrr........................................
NO!!!!!!!!!! :lol:
Fine. I'll take my name.
But when Happy wins constantly you won't be laughing.
or i will be laughing when my robot flips urs OOTA
who will be laughing then :lol: :rofl: :lol: :lol: :rofl: :lol: :lol: :rofl: :lol: :lol: :rofl: :lol: :rofl: :lol: :lol: :rofl:
Theo
The answer isn't as simple as it may seem.
You'll need to know / work out the amps used by your setup....versus the amps your battery / batteries have to give during a given time.
Try playing with this calculator

..A Harbour Freight motor is probably the equiv of your motors.
