I have recently opened three PhD student/researcher positions in aerial robotics in the fields of mechanical design, control, perception, and AI at the Robotics and Mechatronics department at the University of Twente (The Netherlands)

The links below provide information about the jobs and the application procedure:

One position is on design, prototype realization, and control of a dexterous arm for accurate aerial robotic manipulation:
