The Devdoot™ shop · Parts and suppliers
Robot skills now move from one machine to another. The hard part is the hardware: magnets, motors, gears, sensors, chips and batteries. We connect robot builders with the companies that make those parts, and help them see how much of a robot is made here.
Why it matters now
The 65% line.
Since July 28, 2026, the FCC no longer authorizes new models of foreign-produced mobile robots that are connected, sense their surroundings, navigate on their own and weigh more than 2 kg (4.4 lb), dock included.
A robot avoids the rule only if it is manufactured in the United States and more than 65% of its component cost is domestic, a line planned to rise to 75% in 2029. Assembling imported parts here is not enough.
Models authorized before July 28, 2026 can still be sold. Fixed industrial arms, drones, vehicles and medical devices fall outside this rule. A plain summary, not legal advice.
The directory
What a robot is made of.
Neodymium magnets inside nearly every robot motor.
The single most concentrated part of the chain: most of the world's supply is made in one country.
Suppliers: listing openBrushless motors, servos and complete joint actuators with driver and encoder.
The muscle of every robot, and usually the largest share of its component cost.
Suppliers: listing openStrain wave (harmonic), cycloidal and planetary gearboxes.
Precision reducers set how strong and how accurate each joint is, and few plants make them.
Suppliers: listing openForce-torque sensors, tactile skins, encoders and IMUs.
What a robot feels with. Our trust layer depends on these readings agreeing with each other.
Suppliers: listing openCameras, stereo and time-of-flight depth, LiDAR.
Perception hardware; on a mobile robot it is also one of the parts the FCC rule looks at.
Suppliers: listing openEdge AI modules, microcontrollers, motor-driver and radio chips.
The robot's brain and nerves; also where its network connectivity comes from.
Suppliers: listing openBattery packs, battery management, chargers and docks.
Packs and cells are a large cost line, and the dock counts toward the robot's weight under the rule.
Suppliers: listing openMachined and cast structure, 3D-printed parts, cable harnesses.
The easiest part to make locally, and a quick way to raise a robot's domestic share.
Suppliers: listing openWe list a supplier only after checking where it makes the part. Make one of these? Apply to be listed → Building a robot and need parts? Tell us what you need →
Domestic-content check
How much of your robot is made here?
List the main parts and what they cost you. Tick the ones made in the US.
Enter the cost of each part to see your domestic share.
A quick estimate only, not a legal or FCC determination. Commercially available off-the-shelf items are treated differently, and whether a part counts as domestic follows federal procurement rules. Ask counsel before relying on it. Nothing you type here is sent anywhere.
New parts, same skills
New parts, checked.
Swap a motor, a gearbox or a sensor for a domestic one and the same skill behaves a little differently. The Devdoot™ trust layer, patent pending, makes a robot say “I can’t do that safely” or “I don’t know” instead of a confident wrong “Done”, whatever parts it is built from.
