Systems and techniques for performing a calibration test of an obstacle detection sensor of a drive unit are described. An example system includes a calibration region and at least one drive unit. The calibration region is disposed in an environment and includes a calibration apparatus. The at least one drive unit is operable to autonomously move throughout the environment. The at least one drive unit includes a sensor configured to detect one or more objects within the environment. The at least one drive unit is configured to autonomously transition to the calibration region upon detecting at least one predetermined condition, and perform a calibration test of the first sensor at the calibration region using the calibration apparatus.

Systems and methods for evaluating the performance of three-dimensional (3D) sensors can include, for example, obtaining, via a 3D sensor in a testing apparatus, range information of a scene within a field-of-view (FOV) of the 3D sensor. The scene includes a plurality of targets disposed within the testing apparatus. Each of the plurality of targets is located at a different distance from the 3D sensor in the testing apparatus. A validation of the performance of the 3D sensor at the different distances is performed at a same point in time, based on the range information. An indication of a result of the validation is provided.
