Can you elaborate as to how to we can make sure it will work?

As far as prototyping your ideas, use PVC, galvanized pipe, 2x4's and plywood. Make it as close to scale as possible, but don't worry about the weight or the envelope - just make sure your actual design can meet the requirements. You just want to match the stiffness of the structure out to the grabber and the actual geometry of anything that will interface with the Tetra. This will flesh out alot of what works and what doesn't, and will certainly tell you if it's feasible before you go to the effort of full development.
