@Tom.G Just wanted to say cheers Tom, we are in the process of implementing something along the lines of your suggestion quoted.

Thanks for that suggestion Tom, is the picture attached along the lines of what you were thinking of?

Have considered this before, but finding a string capable of holding sufficient tension while also being narrow / weak enough to be severed instantaneously is extremely difficult.

@Tom.G Yes, the issue of adding the weight of an additional actuator would hinder performance too much. Going back to your idea re replacing the ratchet with a buckle, is there any buckle which could be released non-manually... or if a push button buckle was used and a fixture placed at the...

@Tom.G Cheers for those suggestions Tom, couple things to point out: I'm unsure on how the buckle could be positioned perpendicular to the direction of the straps threaded through it. Implementing slack to the straps would be not be possible given their purpose in tensioning to tilt the head...

@Tom.G The release needs to be solely positional relative to the track i.e. it releases tension at the same point positionally. I can see the potential of this cam lock buckle idea but don't fully understand. See picture attached. Is the orientation of the buckle correct? Where does the cord...

Thanks for that Berkeman, based off your recommendation and my lack of familiarity, I'll rule out the solenoid. Possibly more relevant to my previous forum: Going back to my previous idea as in Picture 1 attached, the ratchet strap reduces length between platforms and tilts the head forward...

Giving a guess, tension needed would be equivalent to an average man having to exert 50% of his strength to pull a light 20cm strap.. I'm unfamiliar with solenoids - firstly, how practical would it be to fit this into a 20cm long strap? Retraction upon de-energizing disconnects the straps how...

Exactly that if possible.. if not fully synchronized with a specific moment, at least someway controllable. No good candidates as of yet.

Yes, it is the same application as in previous forum but didn't want to bombard viewers with too much information; I can filter any ideas based on if I think its feasible in terms of safety, tension needed etc.

Looking for products / ideas on a strap (max 30 cm length) which has a quick release buckle (like in bike helmets) halfway up the strap which can be released without a person manually touching/altering the buckle themselves. For eg: a wireless system where clicking a button on an app releases...

Hi Tom, My apologies for not providing more detail about the track/stopping mechanism (see picture attached). The hardstop is initiated by the "stroke length" of the actuator being reached. Your suggestion did make me think about placing something past the hardstop (just left of end of track in...

I dont believe this would be possible as the head/neck are almost one system by their connection with a bundle of steel rods shown in picture previously. Even if I was able to pre-set tilt with a ramp at top of neck, this would affect the heads movement in the opposite direction?

Unfamiliar with how crossbow triggers work but intuitively, a trigger would need to be pressed somewhere on the model body in order to release tension yes? @Nik_2213

Very good suggestion and possibly something I didn't consider since the attachment point to the track was done before I joined the project. As I said to Tom, I'm very unsure on how much flexibility there is with the current attachment mechanism but something I will have to look into. I think it...
