ARCAS 4th year

Published on Feb 2, 2016

During the 4th and last year of the project, R&D activities have been focused in the indoor integrated experiment with:
- RO-SLAM localization,
- Kinodynamic aerial manipulator motion planning using a directed bi-RRT algorithm
- Priority-based behavioral control including field of view, distance manipulator-observer and obstacle avoidance tasks
- Motion planning initialization and Optimal Reciprocal Collision Avoidance
- Trajectories calculation using a centralized quasi-static approach
- Multivehicle navigation of the planned trajectories including field of view and obstacle avoidance
- Hybrid Visual SWervoing with Hierarchical Task Composition using a multilayer low level controller
- Two aerial manipulators perform a cooperative grasping, transportation and deployment of a long rigid bar
- Cooperative transportation of the long bar following a trajectory that avoids the obstacle

Regarding the outdoor experiments, these are the main characteristics:
- RO-SLAM
- RO-SLAM and GPS approach and grasping with aerial robotic manipulator based on multi-rotor with 7 DoF arm
- Visual Servoing Grasping with the Flettner helicopter and LWR 7 DoF arm
- Manipulator compensating ground effect
- Increase altitude with the compensation of the load weight and transport to the point of interest
- Detach the service robot
