this article presents the authors ongoing work towards a six degrees of freedom simultaneous localization and mapping (SLAM) solution for the Project AURORA autonomous robotic airship. While the vehicle's mission is being executed in an unknown environment, where neither predefined maps nor satellite help are available, the airship has to use nothing but its own onboard sensors to capture information from its surroundings and from itself, locating itself and building a map of the environment it navigates. To achieve this goal, the airship sensorial input is provided by an inertial measurement unit (IMU), whereas a single onboard camera detects features of interest in the environment, such as landmark information. the data from both sensors are then fused using an architecture based on an extended Kalman filter, which acts as an estimator of the robot pose and the map. the proposed methodology is validated in a simulation environment, composed of virtual sensors and the aerial platform simulator of the AURORA project based on a realistic dynamic model. the results are hereby reported.

In this paper we report on the design, implementation and testing of a manipulator for a multirobot task involving the transport of an extended payload by two robots. the overall task involves three main manipulation components, namely payload pickup, terrain traversal and putdown at the deployment site. the manipulator was specifically designed to meet the requirements of these manipulation operations. It comprises three main components, a two-degree of freedom arm, a passive but compliant one-degree of freedom wrist, and an active gripper mechanism. Low-level control is accomplished using a small network of PIC microcontrollers. A key design goal of the control architecture was software and hardware modularity: separate modules drive the motors, measure encoder counts and support a range of low-level behaviors suitable for the task. Several sensors were specifically designed to enhance the compliance of the system. High-level control is based on an on-board laptop computer. the paper describes the motivation, the design and implementation, and the experimental results to date.
