OptObstacles at the SBFT 2025 Tool Competition – UAV Testing Track

2025

Abstract

We present OptObstacles, a test case generator for unmanned aerial vehicles (UAVs) that leverages metaheuristic search over obstacle configurations (sizes, positions, and rotation angles). Our approach searches for challenging test cases by optimizing for objective functions designed to represent (1) constraints on geometric validity (e.g., non-overlapping obstacles), (2) custom heuristics (e.g., potentially favorable positions relative to the expected UAV trajectory), and (3) simulation outcomes (e.g., minimum distance between UAV and obstacles). In our preliminary testing, our approach generates challenging scenarios, which yield a higher rate of soft fails (compared to hard fails). OptObstacles is submitted for participation in the UAV testing competition at SBFT 2025, and our code is publicly available at https://github.com/zhekai-jiang/UAV-Testing-Competition.

Unmanned aerial vehicle

An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.

Rotation

Rotation or rotational motion is the circular movement of an object around a central line, known as axis of rotation. A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a center of rotation. A solid figure has an infinite number of possible axes and angles of rotation, including chaotic rotation (between arbitrary orientations), in contrast to rotation around a axis.

Rotation formalisms in three dimensions

In geometry, various formalisms exist to express a rotation in three dimensions as a mathematical transformation. In physics, this concept is applied to classical mechanics where rotational (or angular) kinematics is the science of quantitative description of a purely rotational motion. The orientation of an object at a given instant is described with the same tools, as it is defined as an imaginary rotation from a reference placement in space, rather than an actually observed rotation from a previous placement in space.
