We have used Easyrig 2.5 to carry a 13kg, 5-camera rig in difficult terrain in two research projects. Both project use the images from the cameras to compute a 3D-model of the objects of interest (trees in one project, the ground in the other). Before we started the project I did not know of Easyrig. Now I don't know how we could have made the projects without it! Our research results have so far been published at scientific conferences in Australia and Portugal.
