Rules regarding safety links?

[typhoon_driver]

Typhoon 2 used a military grade 1000amp connector that was worth a few thousand pounds which was well slotted in. The middleweights used a screw mechanism that had to be unscrewed.

From reading through this, it does seem as though you are overthinking the problem. The link isn't all that big a deal and there will always be the odd one or two that pop out.

Not totally overthinking it just don't like the thought of handling a live 150A connector and if I can have a low voltage low current link then I can use a military connector that isn't succeptible to vibration or shock

Thanks for the replys, i read the rules and have them as my bible for creating my machine, but again there is nothing in there to state that custom devices can't be used, which was the main point of asking for clarification on using a custom part.

in regards to damage to the link, first off it would be built in using tough materials i'm experimenting with the use of 3D printed nylon so it should be a strong unit for the purpose, but i'm also looking into molding's ( something that i do regularly) so there is no reason for it to fail providing it can be mounted in a way to reduce damage.

However damage can occur even in the most unlikely of places regardless of planning but with all machines of doom carrying spares is somewhat of a necessity and i see no reason not to carry 2 or 3 spare parts of the link, which again the way its designed allows for it to be unscrewed/bolted and replaces in only a few minuets (whats 4 retaining screws and 2 contact screws really?)

Again i was looking to do something different keeping the unit contained and more professional looking without causing issues with the tech check.

I know none of you know me or my work in other hobbies but if you did you would understand that my work i treat as art as well as functionality so if it looks just hashed together it get scrubbed and i find something better.

Please keep suggestions coming, input is always welcome.

Wearing gloves is the easier option.

Similarly my heavyweight link has a pull cord

I think there was something in a ruleset (I can't recall the precise one off the top of my head but it indicates the thought process) that it had to be a direct disconnect rather than going through a relay or regulator of any kind, and since relays can weld shut/be damaged by shock and FETs can go open crcuit if you look at them funny, you can see why a direct disconnect is safer. You can get anti-spark connectors to minimise the risk and it's honestly not something I'd ever be concerned about grabbing. Plus more components always means more parts that can go wrong...

I think of combat robotics as a sort of art too, gods know I fuss over the placement of parts and making it all look logical, but if you're trying to make every single part fit artistically you're going to have your work cut out with the rest of the electronics!
