It appears a tinkered minecrawler got lost on its way back to Splitiron Mines and powered down to conserve energy. I believe I can get it back to the mine's power station after I take its controls before it's completely drained. There are buttons near the top of its hull:
Display Battery Charge -- Returns the current battery power.
Mechnomagnetic Pulse -- Detects sources of mechnomechanic power surrounding the minecrawler. Usage drains 1% of charge.
Draw Power -- Inserts energy prongs into valid sources of power to charge batteries.
Drive the minecrawler back to the battery charging station in the Splitiron Mine ( 183, 137, 240 ) /waypoint 182.79, 136.79, 240.02.
