Circumnutations as a penetration strategy in a plant-root-inspired robot

2016 IEEE International Conference on Robotics and Automation (ICRA), 2016
In this paper, we present a study on peculiar plant root movements, named circumnutations, adopted by plants as an efficient strategy to penetrate the soil and implemented in robotic roots to improve their performance in exploration tasks. The robotic root is able to bend and interact with soil owing to a soft actuation mechanism based on the ...

Experimental investigation of circumnutation-inspired penetration in sand

Bioinspiration & Biomimetics
Abstract Probes that penetrate soil are used in fields such as geotechnical engineering, agriculture, and ecology to classify soils and characterize their properties in situ. Conventional tools such as the Cone Penetration Test (CPT) often face challenges due to the lack of reaction force needed to penetrate stiff or dense soil layers ...

Measurement of circumnutation in maize roots.

Microgravity science and technology, 1995
The movement of growing primary roots of maize was measured using a computer driven video-digitizer system. Real time measurements with two perpendicularly mounted video cameras permit measurements of growth movements in three dimensions and allow precise control of growth experiments.

Circumnutation, Rhythms and Light-Regulated Movements in Plants

1980
Of all Charles Darwin’s contributions to the study of plant movements, none is more fundamental than his suggestion that circumnutation is the basic process underlying the tropistic responses of stems and roots to unilateral stimuli such as light and gravity. Like Pfeffer before him (1), Darwin appreciated that cells around the perimeter of cylindrical

Resolving Circumnutational and Gravitropic Movements of Root Tips

1997
The movements of growing roots allow them to find the path of least resistance through soil and maximize the utilization of soil resources by proper deployment of members of the root system in the rooting volume. Circumnutational and gravitropic movements of root tips are important components of these processes.
