New hw robot prodigy

**ady** · 14th May 2007, 17:42

Hi people, purchased a robot off ebay (janus) basically it has been stripped, new wiring, new 12mm polycarb armour, hydralics seem to be working fine, in 2 minds whether to remove this or leave it in. Im now stuck on the pneumatics. The previous owner couldnt tell me much. i know it runs of a relay which is working but i know nothing about refilling the thing. i have attached a pic to profile of the bottle he gave me. it seems to push into a connector on the side of the robot which is linked to a co2 (i presume) bottle permanently fixed to the robot. anyone tell me how to refill this or any other info.the big bottle thats not fixed to the robot has a label on it but that doesnt say much,it has a good size ram on it but i dont know how powerful it is,i have attached a link of how the robot once looked!

Its a fairly standard Airline quick coupling ....it looks similar to an AP97.

You appear to have a bought a bot that uses High Pressure Air.
For your pressure specs look at the donor and receiver bottle FILL PRESSURE rating.

your right woody i have looked further and it does uses high pressure air, the big bottle says 300 bar? the bottle on the bot says 3000psi i think, but hard to read.

Im not sure if the FRAs current rule set includes high pressure air.... I.E. Onboard storage pressures above 1000 psi.
Youd need to supply your own donor bottle at each event...getting it refilled could be a pain.

Id be inclined to swap to the readily available co2.

Got a decent pic of the insides?

300 Bar sounds right.
Youll more than likely have a small scuba tank ( 232 bar )in the bot as a receiver.

i have no inside pics at mo as it is all stripped out, hopefully in the next couple of weeks it will be finished and i will post a full set of pics of the finished product! the bottle in the machine looks the same as a co2 bottle i see in alot of machines. do you think im reading it right at 3000psi, or could is be 300?

Feel free to email me during the rebuild if you think I may help.

Cheers Alan

Its a standard compressed air bottle. the black and white painted top is the giveaway.

basicly you have the same option as me with Obsidian, leave it as it is or convert to co2.

So how is Janus apart from that? Is the drive working ok?

btw, for now I decided to keep Obsidian on Nitrogen and fill it to 70Bars. 300 bars in the robot is not allowed anyway (under FRA rules). And I totally agree with that rule.
