BOMAG ROBOMAG

Summary

The BOMAG ROBOMAG is a diesel-powered tandem roller platform built in two variants (BW 154 for asphalt, BW 177 for soil) as a technology study for autonomous compaction subsystems, developed with the Technical University of Kaiserslautern. It covers compaction across earthmoving and road paving, with the Emergency Brake Assist subsystem in full production since September 2024 and Stage 1 radio remote control available as a factory option. The ROBOMAG remains classified as a prototype; full autonomous compaction has not been demonstrated outside trade shows.

Compaction

The ROBOMAG BW 154 and BW 177 are R&D platforms where BOMAG tests subsystems for autonomous compaction individually, including LiDAR-based obstacle detection, GPS geofencing for area definition, and programmed rolling patterns. BOMAG and Autonomous Solutions Inc. are separately pursuing the BW 213 single drum roller with Variocontrol intelligent compaction as the commercial path to autonomous roller operation.

Compaction (Rolling Train)

The ROBOMAG concept and the BW 213 collaboration both target rolling-train compaction behind a paver. The BW 213 uses articulated steering and handles compaction layers 300 to 1,200 mm thick.
