Solar panel install

A tool change (a vacuum area frame, then a suction cup, then a nut runner) finishes the task in 7 of 8 runs.

ApproximationSimulated, verify on hardwareProduct mode: not part of the pre-registered experiment
The task, in plain words
Solar panel installation: a solar module (1000 x 600 mm, 35 mm thick, 8 kg) waits on its stand beside the two mounting rails. Lift it onto the rails and set it down against the rail end stops (within 5 mm), then start the clamp nut (13 mm hex) at the middle of its long edge on its thread and tighten it to 6 N m.

Planned into 3 steps; 50 tools tested on 3 conditions each, 255 screen runs.

Caveat: 3 of 3 steps of this setup run on approximation models. A labelled approximation (suction seal, soft arm, latches, threads, valves): verify on hardware. Each tool's full modelling note is under “Show all data”.

Watch the run

Recorded physics, not animation: each replay re-ran a scored run with recording on, on the same condition (nominal placement, seed 0), and plays on one clock.

Click a step to jump both replays to it. Hatched gaps are a head switch or tool change: a fixed time, not simulated.

In words: the recommended setup (Tool change: Vacuum area frame > Suction cup > Nut runner) does all 3 steps and finishes at 62.4 s.

Step by step

Every tool the Studio can simulate tried every step it could do, on 3 conditions each. Here is who could do each step, which tool the recommended setup uses, and why.

Why it takes 3 tools

  • No single tool passed every step in the screen (50 tools, 3 conditions each).

Why this setup over the other finalists

Ties on completion (88%), the weakest step and cycle time, and is simpler: 1768 g against 1791 g.

The rule: finish the task most often, then the strongest weakest step, then the shortest cycle, then the simplest setup.

Step 1 of 3

Place the panel

Tool 1 of the change

Vacuum area frame, 2 x 3 cups, 600 mm

rated 8.47 kg on a smooth face (holding force over a 1.5 safety factor)

88% of full-task runs passed this stepApproximation

  • Caveat: Suction is an approximation(more)

    Suction is an approximation: the seal is a geometric test gating a capped adhesion force; no air flow, leak rate or porosity.

  • Caveat: The clamp is an approximation(more)

    The clamp is an approximation: a 13 mm hex modelled 15 mm tall so the simulated socket can seat (a standard M8 nut is 6.8 mm tall), on a helical joint with a torque ramp; it does not press the panel. The panel is a rigid slab.

  • Caveat: Suction cup (approximation)(more)

    Suction cup (approximation): a compliant lip of rigid segments on a bellows spring with a limited tilt; the seal is a geometric test (every lip segment touching the face, part material under 13 rays inside the lip) gating a MuJoCo adhesion actuator capped at vacuum x lip area (at most 60 kPa). The lip must touch the face: no pull across a gap. Not modelled: air flow, leak rate, porosity, vacuum build-up time (the vacuum follows the shared close ramp and is cut the control tick the seal is lost), lip material hysteresis, peel dynamics beyond the contact distribution. The lip's friction is the part's. Treat suction results as a screen, then verify on hardware.

Tool 2 of the change

Suction cup, 10 mm bellows

88% of full-task runs passed this stepApproximation

  • Caveat: The clamp is an approximation(more)

    The clamp is an approximation: a 13 mm hex modelled 15 mm tall so the simulated socket can seat (a standard M8 nut is 6.8 mm tall), on a helical joint with a torque ramp; it does not press the panel. The panel is a rigid slab.

  • Caveat: Suction cup (approximation)(more)

    Suction cup (approximation): a compliant lip of rigid segments on a bellows spring with a limited tilt; the seal is a geometric test (every lip segment touching the face, part material under 13 rays inside the lip) gating a MuJoCo adhesion actuator capped at vacuum x lip area (at most 60 kPa). The lip must touch the face: no pull across a gap. Not modelled: air flow, leak rate, porosity, vacuum build-up time (the vacuum follows the shared close ramp and is cut the control tick the seal is lost), lip material hysteresis, peel dynamics beyond the contact distribution. The lip's friction is the part's. Treat suction results as a screen, then verify on hardware.

Why this tool

  • With the “Suction cup, 25 mm bellows” in its place the setup also finished 7 of 8 runs; this one is lighter (1.77 kg against 1.79 kg).
  • A finalist with the “Suction cup, 16 mm bellows” in its place finished 4 of 8 runs, against 7 of 8 with this one.

What the data cannot say: 22 other passing tools were not in a finalist: the Studio's ranking chose between them (screen success, then fewer actuators, less mass, a shorter step), and the page data does not record those values per tool.

    The clamp is an approximation: a 13 mm hex modelled 15 mm tall so the simulated socket can seat (a standard M8 nut is 6.8 mm tall), on a helical joint with a torque ramp; it does not press the panel. The panel is a rigid slab.

  • Caveat: Process tool (approximation)(more)

    Process tool (approximation): a rigid tool used by the Studio's own twist or push primitive. The nut runner's spindle is the wrist's roll through a torque-limiting clutch [assumed]; the tamper's stage is a spring that slips at its overload force. The torque, the force and the contact are simulated; the process (thread cross-threading, bed compaction) is not modelled beyond them. Verify on hardware.

Vacuum area frame, 2 x 2 cups, 300 mmVacuum area frame, Studio onlyrated 4.15 kg on a smooth face (holding force over a 1.5 safety factor)
Caveat

Vacuum area frame (approximation): the cups of the suction cup model on a rigid frame, each with its own seal test and its own vacuum valve (a cup that does not seal stays off). The holding force is the sum of the sealed cups' caps; the payload is that force over a safety factor (1.5 smooth, 2.0 porous, 2.5 swivelling, all [assumed]) at 1 g. Only the smooth rating is a simulated claim: the porous and swivelling ratings are arithmetic on the same force, because no leak, porosity or swivel is simulated. Not modelled: a shared vacuum source and its flow, the leak of an unsealed cup into the others, the frame's flex, peel across a long face, foam or needle area grippers. Treat frame results as a screen, then verify on hardware.

Nut runner, 13 mm hex socketProcess tool, Studio onlyrated 6.7 N m (clutch cap 10 N m); members at least 12 mm tall
Caveat

Nut runner (approximation): a rigid hex socket with a guide funnel on a lateral float; it engages a hex member by shape. The Studio wrist's roll is its spindle [assumed], at the wrist's speed: a clutch limits the torque to its cap (10 N m, under the wrist's 15 N m) and lets go at the release. The socket's walls are stacked slices so the simulator's contacts are as stiff as steel (a solver artifact). Supported in the Studio: members at least 12 mm tall. Not modelled: a motor, a torque transducer, cross-threading, socket wear, a reaction arm. Simulated, verify on hardware.

Tamper pad, 200 mmProcess tool, Studio onlyrated 40 N (the stage slips at 60 N)
Caveat

Tamper pad (approximation): a rigid, level 200 mm square pad on a spring stage that slips at 60 N, so the pad never presses harder than that within the stage's 60 mm of travel. Not modelled: pad deformation, vibration or impact compaction, mortar flow, the pad's edge catching a joint. Simulated, verify on hardware.

Rate of screen runs passed, with the count and the failure modes. "Carried": screened from the state the earlier steps leave. Pruned: a capability or fit check ruled the candidate out before any physics.

Pruned reasons (3)
  1. 1a nut runner turns a fastener; it cannot pick or hold a part
  2. 2integrator rule R05: tightening "Solar panel on rails" to 5.8 N m is a process step for a nut runner; other tools turn a member only up to hand-tight, under 4 N m [assumed]
  3. 3integrator rule R09: a soft arm is not used to insert (it cannot hold a member stiffly along the seat axis)

Sensitivity to the change times

Re-ranked with tool changes of 3, 6, 7.5, 10, 12 s and head switches of 0.75, 1.5, 3 s (15 pairs): the recommendation does not change, and the order changes in 0 of 15. Change times are a fixed clock advance, so cycle times are recomputed exactly from the same runs.

Caveats

  • The floating wrist abstracts the arm: there is no arm reach or arm collision model.
  • Presenting a multi-tool head is a fixed tilt per segment plus a fixed time, not a simulated motion.
  • A tool change is a fixed time, not a simulated docking.
  • Controllers are scripted and open-loop on the placement error.
  • A recommendation is a simulation ranking under the stated conditions, not a hardware guarantee.
