The goal of the project is to implement robotic agents that could rapidly build structures from random objects in a disaster/crisis situation to facilitate operation of other robotic agents, or fast and affordable accommodation of the injured groups, e.g. to facilitate operation of rescue agents in a post-earthquake situation. We are proposing a system that employs robotics manipulators (UR5 industrial arm equipped with a gripper in our experiments) to stack objects with arbitrary shapes to construct a rigid wall. Some of the challenges in this problem are: 1) Planning the optimal stacking order and relative placing of the objects 2) Reliable grasping and transporting of arbitrarily shaped objects 3) Accurate detection and localization of the arm and the objects The system is being implemented over ROS to connect to and control the UR5 arm, and MoveIt package is employed to perform collision aware trajectory planning for the manipulator/grasper set. A variety of objects with different shapes and features, e.g. deformability, are considered for the experiments.
