Pictures of a number of targets on the platform are taken from the basket of a cherry picker, while the hexapod is driven to different elevations. Relative positions of the targets provide a measure of the deformation of the platform.

The Yuan-Tseh Lee Array for Microwave Background Anisotropy (AMiBA) is a forefront instrument for research in the field of cosmology. It is the first and only Cosmic Microwave Background (CMB) telescope for Asia and the first major international astronomical project being led by Taiwan. This project is designed, constructed, and operated by ASIAA, with major collaborations with the National Taiwan University Electrical Engineering (NTUEE) and Physics (NTUP) Departments, and the Australia Telescope National Facility (ATNF). Additional contributions were also provided by Carnegie Mellon University (CMU), the National Radio Astronomy Observatory (NRAO), and the Jet Propulsion Laboratory (JPL). Most importantly, this project has established experimental cosmology as a viable field in Taiwan, assembled a team capable of leading, designing, and building frontier instruments. Young students, engineers, and faculty, have been trained, cultivated, and mentored for Taiwan.
