Trajectory Optimization to Enhance Observability for Bearing-Only Target Localization and Sensor Bias Calibration [PDF]
BiomimeticsThis study addresses the challenge of bearing-only target localization with sensor bias contamination. To enhance the system’s observability, inspired by plant phototropism, we propose a control barrier function (CBF)-based method for UAV motion planning.

Proper PIN1 distribution is needed for root negative phototropism in Arabidopsis. [PDF]
PLoS ONE, 2014 Plants can be adapted to the changing environments through tropic responses, such as light and gravity. One of them is root negative phototropism, which is needed for root growth and nutrient absorption.

Plant Phototropic Growth [PDF]
Current Biology, 2015 Plants are photoautotrophic sessile organisms that use environmental cues to optimize multiple facets of growth and development. A classic example is phototropism - in shoots this is typically positive, leading to growth towards the light, while roots frequently show negative phototropism triggering growth away from the light.
