A dual peg-in-hole task from BESS (battery energy storage) pack assembly, built as a MuJoCo task family with a proposal-and-gate pipeline.
Three line vendors independently describe the same split. Autowell names "power cable and electrical system assembly" and "wire harness connection" as discrete stations; Indygreen lists "busbar connection, wiring"; xmacey sells an "automated module line with configurable manual PACK assembly stations".
Module stage automated, pack stage people. Busbar placement is the pack-stage operation you can watch a human do.
Why it is hard: dual peg-in-hole — two pegs constrain position and yaw, and they couple.
