Abstract:
This thesis presents an application of decentralized multirobot box carrying using behavior-based
architecture. The box carrying task is a tightly-coupled task, in which two robots have to carry a box
over their tops. Little movement error will result in a fall of the box. With carefully designed
behaviors, the robots can work cooperatively and effectively. We divided the behaviors into two
types: individual behaviors and group behaviors. Group behaviors, embedded as layers in the
behavior-based architecture, act as a mechanism to induce coordination and synchronization among
robots. We tested different types of movement such as going forward, turning, passing a narrow
passage and switching roles to illustrate the validity of the proposed method. The results indicates
that the robots can move the box to a specified goal without falling down with an average success
rate of 65 percent
