Robots that feel every connection click.
Cerebel is building touch-aware robots for AI racks. They plug in cables, fiber and coolant quick-disconnects, feel each latch engage, and keep a force record of every connection they make.
What we solve
Connection work that needs a sense of touch.
Connectors that look seated but aren’t
- The problem
- A plug can sit flush with its latch unengaged. It passes a visual check and fails later.
- What the robot does
- The fingertips feel the latch click and the force drop, then confirm with a gentle pull before moving on.
Ports the camera can’t see
- The problem
- Dense cabling hides ports and latches behind connector bodies and other cables.
- What the robot does
- Touch finds the port edge and guides the insertion where vision is blocked.
Fragile fiber and coolant lines
- The problem
- Too much force damages fiber and transceivers; too little leaves a quick-disconnect that leaks.
- What the robot does
- Grip and insertion force are felt and controlled in real time, connection by connection.
No record of how the work was done
- The problem
- Once a rack ships, there is no proof each connection was made correctly.
- What the robot does
- Every connection is logged with its force trace: a quality record you can audit.
In development with design partners. The fingertip sensors are built; the touch-aware model is in development.
How it works
Felt, not seen.
The difference between seated and half-seated is a click and a drop in force. A camera passes a plug that looks right. A fingertip knows, and the robot re-seats it before moving on.

The jobs
Eight jobs where touch decides the outcome.
Each job is built from a few atomic tasks in our tactile task taxonomy, and each task depends on skills only touch makes possible.
| Job | Why touch is needed | Atomic tasks | Regimes | Where |
|---|---|---|---|---|
| Seat and verify internal cables and connectors1D | Confirm the latch click; detect half-seats that vision passes | Integration factories | ||
| Route and dress cables in trays and racks1D | Tension, snags and bend under the hand | Factories, data halls | ||
| Connect liquid-cooling hoses and quick-disconnects1D | Seating force felt, not seen | Factories, data halls | ||
| Swap optical transceivers in dense cabling1D + rigid | Reach between cables without disturbing neighbors | Data halls | ||
| Inspect, clean and re-mate fiber1D | Gentle, precise contact on end-faces | Data halls | ||
| Re-cable after moves and failures1D | Untangling and routing by feel | Data halls | ||
| Bag, wrap and pack components2D / 3D | Film handling, soft packing | Factories, depots | ||
| Swap drives, sleds and modulesRigid + latch | Latch engagement, seating force | Data halls |
Six things touch makes possible
R1
Force-window grasp
Hold firmly enough to keep it, gently enough not to crush, tear or mark it.
Without touch · A fixed grip force either drops soft items or damages them.
R2
Slip reflex
Feel slip begin and correct before the object visibly moves or falls.
Without touch · Slip is noticed only after the item is gone, if at all.
R3
Contact-guided seating
Find, align and seat a part by feel where the camera can’t see, and detect the moment it seats.
Without touch · Pushes to a position, not a contact state; jams or leaves parts half-seated.
R4
Sustained contact tracing
Hold a target force while moving along a path: pressing, smoothing, sealing, tracing an edge.
Without touch · Force varies with surface height; gaps, wrinkles and unbonded sections.
R5
Tension and shape control
Shape a flexible object through the tension at the grasp points: stretch, coil, untangle, tuck.
Without touch · No sense of tension; over-pulls, tears, or leaves slack.
R6
Tactile verification
Confirm by touch that a step succeeded (held, single item, seated, sealed) before moving on.
Without touch · Reports success on a step that did not happen; errors ship silently.
All fifteen atomic tasks
00Verified hold and transportRigid
Confirming by touch that an item is held, and keeping it held through transport, handover and release.

From Cerebel’s Tactile Manipulation Task Taxonomy v1.0. The taxonomy defines each task and how it is measured; it does not report results.
Where it works
From the integration line to the data hall.
01 · Rack integration
Seat and verify every cable, fiber and coolant quick-disconnect before the rack ships.
02 · Data halls
Fiber, transceivers and re-cabling around the clock, with a touch record of every connection.
Capacity
Hands for connection work where hiring is hard.
Evidence
A force record for every connection made.
Reliability
Fewer half-seated connectors reaching production.
