Robot Farmers: Autonomous Orchard Vehicles Help Tree Fruit Production

Marcel Bergerman, +6 more
- 12 Mar 2015 - 
TL;DR: Perception and navigation systems for a family of autonomous orchard vehicles are presented to enable safe and reliable driving in modern planting environments and indicate that replacing ladders with autonomous vehicles will make orchard work safer and more comfortable.
Proceedings ArticleDOI

A practical obstacle detection system for autonomous orchard vehicles

Gustavo Freitas, +3 more
TL;DR: Tests conducted at the experimental orchard-like environment in Pittsburgh and an actual apple orchard in Washington state indicate that the method is able to detect people and bins located along the vehicle path, and is also capable of dealing with objects as small as 15 cm tall as long as they aren't covered by grass.
Journal ArticleDOI

Multi-robot coverage path planning using hexagonal segmentation for geophysical surveys

Hector Azpurua, +3 more
- 01 Aug 2018 - 
TL;DR: A methodology that segments the environment into hexagonal cells and allocates groups of robots to different clusters of non-obstructed cells to acquire data is proposed that addresses the problem of multi-robot area coverage path planning for geophysical surveys.
Journal IssueDOI

Kinematic reconfigurability control for an environmental mobile robot operating in the Amazon rain forest

Gustavo Freitas, +4 more
- 01 Mar 2010 - 
TL;DR: In this paper, different kinematic control strategies to improve robot mobility are proposed based on ground clearance and orientation, ground clearance, stability margin, and wheel traction efficiency, and a multiobjective optimization approach is formulated to determine a set of optimal solutions and establish a trade-off optimal solution.
Journal ArticleDOI

Autonomous Aeromagnetic Surveys Using a Fluxgate Magnetometer.

Douglas G. Macharet, +8 more
- 17 Dec 2016 - 
TL;DR: A novel magnetic survey pipeline is proposed that aims to increase versatility, speed and robustness by using autonomous rotary-wing Unmanned Aerial Vehicles (UAVs) and the development of a state-of-the-art three-axis fluxgate is discussed, showing the efficacy of the methodology in detecting an artificial ferrous anomaly.
