Rice Autonomous Harvesting: Operation Framework
Journal of Field Robotics, 2017This paper reports on an operation framework for autonomous rice harvesting. We developed an integrated algorithm for robotic operation and cooperation with farmworkers to automate each subsection of the harvesting and unloading process and of the processes that bridge them (homing and restarting).

Energy Harvesting for Autonomous Sensing
Key Engineering Materials, 2007Autonomous, wireless structural health monitoring is one of the key goals of the damage monitoring industry. One of the main roadblocks to achieving autonomous sensing is removing all wiring to and from the sensor. Removing external connections requires that the sensor have its own power source in order to be able to broadcast/telemetry information ...

Energy Harvesting for Autonomous Wireless Sensor Networks
IEEE Solid-State Circuits Magazine, 2010Wireless sensor nodes (WSNs) are employed today in many different application areas, ranging from health and lifestyle to automotive, smart building, predictive maintenance (e.g., of machines and infrastructure), and active RFID tags. Currently these devices have limited lifetimes, however, since they require significant operating power.

Smart autonomous grain carts for harvesting-on-demand
2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2017In this work, we address the problem of centralized scheduling and motion planning for multiple grain carts with finite capacity that serve a group of combine harvesters engaged in a harvesting operation. First, we solve a facility location problem of finding the optimal depot position to minimize the distance traveled by the grain carts.

A Fully Autonomous Integrated Interface Circuit for Piezoelectric Harvesters
IEEE Journal of Solid-State Circuits, 2012This paper presents a fully autonomous, adaptive pulsed synchronous charge extractor (PSCE) circuit optimized for piezoelectric harvesters (PEHs) which have a wide output voltage range 1.3-20 V. The PSCE chip fabricated in a 0.35 μm CMOS process is supplied exclusively by the buffer capacitor where the harvested energy is stored in.

Piezoelectric pressure harvester for autonomous sensors
Smart Structures and NDE for Energy Systems and Industry 4.0, 2019Determining the exact location of people and objects is a big benefit in times of IoT. It can achieve a tailored surrounding for humans for example by controlling lights or air conditioning systems when needed thus saving energy. It can also help with a smoother navigation for example by pointing to available spaces for parking cars or storing goods ...

Energy harvesting and power management for autonomous sensor nodes
Proceedings of the 49th Annual Design Automation Conference, 2012Wireless sensor nodes that are self-powered by extracting their energy from their environment are a new opportunity for monitoring purpose. Since the available energy is not constant over time and due to very low harvested power levels, efficient energy and power management strategies are mandatory for improving their autonomy.
