Abstract: The development of robots featuring holonomic drivetrains, more exactly swerves, is a comprehensive area of study with numerous potential applications across diverse industries and fields such as metallurgical or car production, where heavy weight mobile transporters are required. Unfortunately, the narrow use of this new technology produced in limited batches and its poor documentation led to its avoidance in some fields, such as hospitality or mining. These drivetrains can precisely navigate through difficult terrains and environments, making them an optimal fit for search and rescue operations, where the need for quick and efficient mobility in remote, hard-to-reach areas is paramount. Moreover, sensors, LIDARs and cameras can be mounted on these robots to collect parameters providing information about hazardous environments without putting human lives at unnecessary risk. Due to their high modularity, such chassis can be mounted on patients’ beds in hospitals, where there is not enough space for complex maneuvers. Thus, mobility is enhanced in crowded situations where patients must be moved from one room to another, or during an emergency when an efficient evacuation is crucial. To effectively assess the capabilities of the drivetrain, we designed a scaled-down prototype. We collected data on mobility, off-road capability, modularity, and maintenance requirements for our prototype and three conventional chassis. Upon analyzing the test results, we found that the prototype consistently demonstrated high performance, being 15% more efficient when averaged over all the experiments considered. The findings of this study confirm the effectiveness of this new generation equipment and can support its incorporation in various fields, especially healthcare.
