Checked them. The approach clips the handle; the workpiece clears. No wonder my first sketch looked so reassuring.

@AnnaBarnes0590 Use that measured layout to review the complete approach and retreat offline. Include the tool, cables and service access, then ask the integrator to assess a revised mounting arrangement.

The buyer has suggested choosing a larger arm. I'm unsure whether that would address the access issue or simply increase our purchase while leaving the obstruction unresolved.

Going larger should open up mounting options. It might be the most straightforward option to explore.

Bigger could bring another obstruction. Extra reach won't shrink the gripper past that handle.

@IsabelAbbott0039 You're right; more mounting freedom isn't guaranteed. Check each candidate in the measured layout and only favour a larger arm if its full approach works better.

I've decided to base our arm selection on a measured access review. A workable layout for the complete tool and a qualified assessment will be conditions of choosing the arm.

Using an assessed layout as the condition gives the selection a clear basis beyond the reach sketch.
