Model Predictive Path‐Following Control for a Quadrotor

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Automating drone‐assisted processes is a complex task. Many solutions rely on trajectory generation and tracking, whereas in contrast, path‐following control is a particularly promising approach, offering an intuitive and natural approach to automate tasks for drones and other vehicles.

Friction Shock Absorbers and Reverse Thrust for Fast Multirotor Landing on High‐Speed Vehicles

Journal of Field Robotics, Volume 43, Issue 2, Page 1068-1090, March 2026.
ABSTRACT Typical landing gears of small uninhabited aerial vehicles (UAV) limit their capability to land on vehicles moving at more than 20–50 km/h due to high drag forces, high pitch angles and potentially high relative horizontal velocities. To enable landing at higher speeds, a combination of lightweight friction shock absorbers and reverse thrust ...

Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation

Advanced Robotics Research, Volume 2, Issue 1, February 2026.
This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...

Modeling and Control of a Quadrotor UAV

, 2022
Given the increasing use of quadrotor vehicle applications, this project seeks to iden-tify critical trade-offs with respect to modeling, control and vehicle design. With thisgoal, we focus on a very generic/standard quadrotor configuration. A two controlnonlinear 3DOF (degree of freedom) model for the vehicles longitudinal dynamics isused as the basis
