A Plume Tracking Algorithm Based on Crosswind Formations

Alcherio Martinoli, Inaki Navarro Oiza, Thomas Lochmatter

We introduce a plume tracking algorithm based on robot formations. The algorithm is inherently designed for multi-robot systems, and requires at least two robots to collaborate. The robots try to keep themselves centered around the plume while moving upwin ...

Real-time Optimized Rendezvous on Nonholonomic Resource-Constrained Robots

Alcherio Martinoli, Sven Adrian Gowal

In this work, we consider a group of differential-wheeled robots endowed with noisy relative positioning capabilities. We develop a decentralized approach based on a receding horizon controller to generate, in real-time, trajectories that guarantee the con ...

3-D Relative Positioning Sensor for Indoor Flying Robots

Dario Floreano, Jean-Christophe Zufferey, Timothy Stirling, James Roberts

Swarms of indoor flying robots are promising for many applications, including searching tasks in collapsing buildings, or mobile surveillance and monitoring tasks in complex man-made structures. For tasks that employ several flying robots, spatial-coordina ...

An Active Uprighting Mechanism for Flying Robots

Dario Floreano, Jean-Christophe Zufferey, Adrien Briod, Adam Klaptocz, Ludovic Daler

Flying robots have unique advantages in the exploration of cluttered environments such as caves or collapsed buildings. Current systems however have difficulty in dealing with the large amount of obstacles inherent to such environments. Collisions with obs ...

Communication assisted navigation in robotic swarms: self-organization and cooperation

Francesco Mondada

We present a communication based navigation algorithm for robotic swarms. It lets robots guide each other's navigation by exchanging messages containing navigation information through the wireless network formed among the swarm. We study the use of this al ...

Distributed motion planning for ground objects using a network of robotic ceiling cameras

We study a distributed approach to path planning. We focus on holonomic kinematic motion in cluttered 2D areas. The problem consists in defining the precise sequence of roto-translations of a rigid object of arbitrary shape that has to be transported from ...

Enabling Large-Scale Collective Systems in Outdoor Aerial Robotics

Severin Leven

For many real-life applications such as monitoring, mapping, search-and-rescue or ad-hoc communication networks, fleets of flying robots are expected to out-perform existing solutions. Robots can join forces to cover larger areas in less time, act as effic ...

Enabling Collective Operation of Indoor Flying Robots

James Roberts

Collective flying robots show great potential in many diverse indoor applications. Their added robustness, parallel operation and redundancy has clear advantages over a single flying robot. However, flying within cluttered and unprepared indoor environment ...

Aerial Locomotion in Cluttered Environments

Dario Floreano, Mirko Kovac, Jean-Christophe Zufferey, Adam Klaptocz, Jürg Markus Germann

Many environments where robots are expected to operate are cluttered with objects, walls, debris, and different horizontal and vertical structures. In this chapter, we present four design features that allow small robots to rapidly and safely move in 3 dim ...

EmbedIT – An Open Robotic Kit for Education

Robots have often been used as an educational tool in class to introduce kids to science and technology, disciplines that are affected by decreasing enrollments in universities. Consequently, many robotic kits are available off-the-shelf. Even though many ...
