One thought: when the saw is spinning, you may want to put quite a lot of pressure on the saw blade. With the 4-bar system and the servo pushing on only one side, is the mechanism going to be stable or is there a chance it'll start twisting? Feels like there might be a fair bit of flex with it being made of HDPE, and applying the force asymmetrically might not help...

Thanks! You're making a valid point - in the earlier tests (like the one shown) the weapon module moved from side to side - this is down to the 4 arms holding it having play in them, which extrapolated to the weapon module. Aside from doing up the bolts, the two arms on the left are now from 10mm HDPE which makes the entire assembly a lot more solid - there's hardly any room for the module to move other than forwards and backwards.

Having said that, I'm curious how it'll behave during weapon testing. I do believe if it would lead to problems it'd simply be a matter of sliding the servo more into the robot. I drilled and retapped the servo horn to take M4 bolts, so if need be I can run a shaft through the back end of the weapon module and have the servo sit dead center.
