A polished design deck is not a prosthetic arm.
AI roast score: 41/100 (F)
The idea
You have CAD, PCB plots, and a list of things that can fail. You do not yet have a hand people can trust, wear, or buy.
The roast
This is not a product yet. It is a pile of design choices wrapped in confidence. You keep saying “design artwork, not a physical prototype” and “not yet measured,” which is honest, but it also means the core claim is still fantasy. In hardware, drawings do not help a patient grip a cup. Your own slides admit the big gaps: no integrated test, no measured grip force, no full flexion time, no validated power system, no clinical results. That is not a small gap. That is the whole product. The deck spends a lot of energy proving you can think in systems, but almost none proving the system works outside CAD. The market does not pay for topology sketches. The worst part is the mismatch between ambition and proof. You talk about a modular arm, future wrist/forearm/elbow/shoulder concepts, and partnerships, while the only concrete thing is a bench palm with unresolved safety and load-path questions. This is how hardware teams die: they confuse engineering progress with customer progress, then run out of time, money, and credibility.
Red flags
- The deck repeatedly says there is no physical prototype and no integrated test.
- The biggest unknown is regulators, but there is no tested safety path yet.
- You are pitching a whole modular arm while only the palm exists as design work.
Verdict
Freeze the big vision and prove the palm can safely work in real life before anyone takes the rest seriously.
