International Journal of Social Robotics. We present an approach to continuous motion planning with multiresolution in time. Our approach is based on stochastic trajectory optimization for motion planning STOMP and designed to decrease the optimization time in order to enable Our approach is based on stochastic trajectory optimization for motion planning STOMP and designed to decrease the optimization time in order to enable frequent replanning.
Since service robots operate in environments with dynamic obstacles, it is likely that planned trajectories become invalid over time.

Thus, it grafikprkgrammierung not necessary to provide trajectories with a uniform high resolution. In addition to employing temporal multiresolution, we speed up trajectory optimization by initializing replanning with the previous plan. Our experiments show that multiresolution STOMP reduces the planning time and, hence, is able to avoid dynamic obstacles. RoboticsMotion Planningand Service Robots. Micro aerial vehicles MAVssuch as multicopters, are particular well suited for the inspection of human-built structures, e.
Today, the operation of MAVs in the close vicinity of these Today, the operation of MAVs in the close vicinity of these structures grafikprogrmmierung a human operator to remotely control the vehicle. For fully autonomous operation, a detailed model of the environment is essential. Building such a model by means of autonomous exploration is time consuming and delays the execution of the main mission.
In many real-world applications, a coarse model of the environment already exists and can be used for highlevel planning. Nevertheless, detailed obstacle maps, needed for safe navigation, are often not available. We employ the coarse information for global mission and path planning and refine the path on grafikptogrammierung fly, whenever the vehicle can acquire information with its onboard sensors.

To allow for fast replanning during the flight, we present a 3D local multiresolution path planning approach making online grid-based planning for our MAV platform tractable. Towards autonomous navigation of an UAV-based mobile mapping system more.
Obstacle detection and real-time planning of collision-free trajectories are key for the fully autonomous operation of micro aerial vehicles in restricted environments. In this paper, we propose a complete system with a multimodal sensor In this paper, we propose a complete system with a multimodal sensor setup for omnidirectional obstacle perception consisting of a 3D laser scanner, two stereo camera pairs, and ultrasonic distance sensors.
Detected obstacles are aggregated in egocentric local multiresolution grid maps. We generate trajectories in a multi-layered approach: We evaluate our approach in simulation and with the real autonomous micro aerial vehicle. Springer Tracts in Advanced Robotics.
