I'm not putting down your idea, having different attachments worked for Tornado and some others. It felt as though at heart, Tornado was always an extremely potent rammer first, and then which ever drum, spike etc. attachment second.
That was kind of my motive behind it, have a machine that's basic function is to put opponents where it can but have this type of interchangeable top section for different weapon to suite
I think your worry will be that the "pod" with the arm needs to be extremely strongly mounted, probably welded or use one continuous piece of material through the robot for strength. If it has to be removable it will more than likely mean bolts, which will have to take a load of force going through them. At this point its raw maths as to whether the bolts you plan to use will take the forces involved before sheering. If the maths looked good I'd have a crack, but if it looks questionable I would say you need to focus on a complete frame dedicated to crushing.
Had the horrible realisation that everything weighed too much, before I had even started wiring and construction it was 14.8kg, too much!
So, after a few talks with roboteers and a swift kick in the right direction the design has dramatically changed. Until I get a rough render think a shorter, wider, sleeker Ming 3 with a hinged wedge/crush zone.
I don't remember these issues when I built mine, suppose it did help it was welded ti and ali
If you are interested I've got a dewalt motor conversion for the linac you're using (same as mine, so should be an easy swap) I'm trying something different when I rebuild my crusher shortly
You use the Duff Norton base? Be interesting to hear, I would be surprised if the motors were very efficient for their size considering they are built in 1972, retro tech!
Some first CAD designs up (Thanks Jarvis)
Comes in at 13.4kg with all 10mm hdpe and hardox front which I am pleased about, the all round protection is pretty good so will work towards this.

That linkage wont work. Make sure the claw pivot point is above the actuator pivot point in both claw up and down positions.
Th shouldn't be a difficult thing to change, I'll look into it.
Jarvis has worked his magic to come up with a slightly different version, compromised having 6mm hdpe top to allow weight for better supports which gives me an extra 200kg worth or crush, happy days
