Grokbot made me a sandwich.
Here's how I did it.
Step 1: I gave it shopping access.
-Servos, stepper motors, filament, aluminum extrusion. It built a parts cart. I approved the order.
Step 2: I had it model the arm in CAD.
-A gripper, joint housings, brackets. Exploded views. Dimensions. I told it to design for a 3D printer.
Step 3: I printed the parts.
-A few machines, a few hours. Layer by layer, the grocery run became a pile of components on the bench.
Step 4: Grokbot hired an IKEA furniture assembler.
-It wrote them a step-by-step manual, handed it over, and they built the arm. Allen key included.
Step 5: I sent the arm to the fridge.
-It opened the door, grabbed the bread, the peanut butter, and the jelly, and set them on the counter.
Step 6: I ate the sandwich.
A plain peanut butter and jelly. The arm stood there next to it. That was the whole brief.
Convenient tools plus a clear brief can get you surprisingly far. Even if the brief is a peanut butter and jelly sandwich.
