4 axes Robot

In centrifuge, repeating the test at different locations on the model or linking two types of tests requires stopping the centrifuge to move or change the on-board equipment. These successive stops cause loading and unloading cycles on the model which can lead to irreversible changes in the condition of the soil. If this is the case, the repeatability of the tests in the same container will be affected. In clay models, it is also necessary to reconsolidate the model after each stop for several hours, which can considerably increase the total test time.

These various considerations led the centrifuge team to acquire a robot, placed in the centrifuge basket. This four-axes robot has a magazine (2) and a tool changer (1). The robot can therefore do a series of operations on the model without stopping the centrifuge.
