The tests are taking place in Józefosław near Warsaw, as part of a project in cooperation with NASA.
The initiative involves academics and students from the Warsaw University of Technology and the Jagiellonian University in Kraków, southern Poland.
Universities from Basel, Switzerland, and San Jose in the United States are also participating.
The first three-day tests of two rovers, equipped with light detection and ranging sensors, stereoscopic cameras, and Ground Penetrating Radar (GPR), concluded on Friday.
More tests will be conducted at the Warsaw university's Center for Geospatial Analysis and Satellite Computing (CENAGIS) in Józefosław, a southern suburb of the Polish capital.
The goal is to determine whether a swarm of smaller autonomous rovers can perform scientific exploration of Mars more efficiently and accurately than large rovers.
The advantage of using a swarm of rovers could be a broader operational range and the ability for the smaller devices to compensate for each other's functions in case of failure, experts say.
