The two road rollers BW154 and BW174 of the Bomag GmbH are research platforms for autonomous road compaction and robot collaboration. In a road production scenario, coordinating different autonomous construction machines such as road pavers, feeders, rollers, and trucks are being researched. As a paver requires a continuous mass flow, feeders and trucks must coordinate accordingly to ensure a steady supply. Likewise, a cooperation of the road rollers for the compression of the material occurs because the compression process is subject to high time and precision requirements.
As part of this, two road rollers were converted to fully autonomous systems and equipped with variable sensors for environmental awareness and surround safety. In addition to developing control concepts for the individual rollers, the lab researched complex cooperation solutions. Here, the systems benefit from the high bandwidths of a local "5G" communication infrastructure.
In addition to the development of real tandem rollers, virtual rollers use a powerful simulation engine. Accordingly, research approaches may run in advance with any number of cooperation vehicles. After successful simulation tests, a transfer of control software and validation takes place on the real platforms.
