An integrator friend once joked: “Clients remember the robot price and forget everything that makes it move.” Behind the joke is field truth—AMD Machines puts robot hardware at roughly 25–40% of project cost and integration at 30–50%; Robolist’s TCO model bands EOAT at $2k–$40k+ and integration engineering at $8k–$60k. Many projects die in week one: not enough IO, gripper late, PLC handshake changes three times.
We split integration into above and below the waterline. Above is equipment. Below is everything that makes the arm repeat on your shift.
Published bands put simple cobot cells around $45k–$75k, and vision/multi-station work around $70k–$130k (Robotomated cost guide)—thicker than an arm-only line item.
Below the surface, layer one: interfaces and wiring
“Plug and play” often means jog when powered. “Plug into your line” is PLC, MES, e-stop, safety relays, tool power, vacuum—every wire has an owner. People beside the cell still need a written risk assessment, often referenced against ISO 10218 / ISO/TS 15066—see Safety & I/O guide.
Layer two: end effector and process proof
Arm arrives; gripper on a truck. Worse: gripper arrives, close time is 1.4 s and 6 s takt dies. Proof is worst case—not one good pick.
Layer three: people and organization
Who trains? Who resets at night? Remote integrator support deferrals cost; it returns as service fees.
Layer four: downtime and opportunity cost
Three days to mount, two weeks to tune—off paper: lost orders, overtime that cannot catch peak. Owners feel this first.
Making the hidden explicit
We are not trying to scare you off integration. Name below-waterline work before PO—a fuller checklist lives in the ROI guide:
Mechanical: flange, fixture mass, extension
Electrical: IO list, e-stop, PLC handshake
Process proof: worst part, takt through EOAT moves
Organization: who teaches, who first-articles, support after integrator leaves
Time: downtime window, rollback if the pilot fails
Once underwater work is named, the debate shifts from “is the arm expensive” to “is this station worth doing now.”
Common questions
Why do first quotes look arm-only?
Is integration really 30–50%?
Can we skip integrator cost by doing it ourselves?
How do I know a quote is complete?
If you only have an arm quote, pause. Ask for the below-waterline list.
