The SIASUN Single-Lift Automotive Assembly Mobile Robot is a heavy-duty autonomous platform purpose-built for marriage operations in automotive final assembly — joining front suspensions, rear suspensions, and power battery packs to the vehicle body. Its single-lift scissor structure with servo motor lifting delivers a 1000 kg load capacity, a 1000 mm lifting stroke, and excellent tolerance to eccentric loads. High-precision navigation accurate to ±10 mm and ±1° combines with synchronized motion control to achieve reliable docking with mainline hangers and station fixtures, while the floating lift platform (X ±125 mm, Y ±50 mm, angle ±2°) compensates for alignment offsets during the marriage process, protecting both takt time and process accuracy.

Driven by a single steering wheel and operating tracklessly, the robot moves flexibly around the final assembly workshop without fixed infrastructure, adapting efficiently to multiple vehicle models and long-cycle production programs. Beyond its core automotive assembly role, the platform suits modern smart factories, warehouses, production logistics, and process-driven material handling wherever repeatable transport, accurate positioning, and safe autonomous operation are required — providing a stable, efficient transport-and-assembly solution that reduces manual handling on the line.
