This is GRACE (stands for Gikadai Robot for Attendance in Complex Environments, named by Prof. Miura who was my supervisor) that I used during my master's and Ph.D. period for some researches related to person identification and awareness estimation. GRACE was equipped with quite rich vision and range sensors (PTZ-cam, wide-angle webcams, two-layered omni LIDARs) and an omnidirectional base. This was one of my most memorable robots because I spent many years (more or less five years) working with her. Although her behavior was not really graceful (maybe my fault), she helped my work very much.
