Studying honeybees' landing on flower: an experimental setup
Nicolas Salvage, Antoine H. P. Morice, Julien R. Serres
Abstract
Landing a helicopter on a moving ship is an error-prone operation, requiring the expertise of highly trained pilots, and benefits greatly from advanced technologies to improve decision-making and action regulation. (Thomas et al. 2021). In stark contrast, landing to forage on a flower looks to be performed with remarkable ease and under visual control in bees (Lehrer and Srinivasan 1992; de Vries et al 2025). Understanding the perceptual behavior of pilots in comparison to that of honeybees is a key driver of innovation in the design of bio-inspired robotic systems. Understanding the mechanisms behind this ability requires accurately tracking the bee’s movement during the landing task. Vision-based tracking techniques using convolutional neural networks (CNNs), such as You Only Look Once (YOLO) algorithm (Redmon et al. 2016), can be specifically trained to detect and track the honeybee-flower system. Our goal is to accurately reconstruct a known trajectory, using a fake bee as a target, with a mean tracking error less than half a centimeter, or about half the length of a honeybee (13 mm).

The bionic Pohod15Leg leg: an exoskeletal ant-inspired leg for load transportation
Julien R. Serres, Ilya Brodoline, Stéphane Viollet
Abstract
Every year, numerous bio-inspired hexapod prototypes are built in various fields of research, such as navigation, social behavior and locomotion. Staying within these three fields, several hexapod robots developed over the last two decades are presented in this review (Manoonpong et al. 2021). The most common category corresponds to hexapods with a mass 0.5∼10kg. All these robots are driven by low-power electric servomotors (each consuming an electric power of around 30W). Servomotor-based hexapods are frequently used because of their low manufacturing cost 0.5∼3k€. Moreover, electric servomotors are easy to drive, as there are usually many prefabricated development boards integrating the control system. To better understand how animals work, for example, how ants run so fast or carry such a heavy load? This requires to estimate the gap between the limits of the animal model and the bio-inspired hexapod. It is therefore relevant to proceed with the hexapod design step by step, considering the current technological limits constraining the robot design process. In this study, we will compare the level of performance of the first exoskeletal ant-inspired leg for load transportation, called Pohod15Leg, designed and fabricated to be compared to the current state-of-the-art in servomotor-based legs, i.e., a bionic leg actuated by 3 Dynamixel AX-18A servomotors, called AXLeg. These two bionic legs will be evaluated in similar experimental conditions with the same test bench, called MiMiC-ANT test bench (Brodoline et al. 2022).

The NOVABOT play: a mini airship dedicated to capturing video of an actor on stage
Youssra Mansar, François Bernier, Sylvain Blayac, Louis Dieuzayde, Julien R Serres
Abstract
The actor's body is present and active on stage, but capture and projection technology enhances its presence, dramatizing its perception by bringing the spectator's gaze closer to it, fracturing her/his image by taking details of the body or face enlarged on screens, sometimes altered, modified and revealing the visible body beyond her/his normal appearance (Mansar 2022; Mansar et al. 2023). These phenomena create a whole new dramaturgy, emancipated from traditional dramatic action, which begins to combine the real and the virtual in an augmented reality, thus disturbing the spectator's perceptive field. A new poetic space is emerging, focusing on a disquiet at the heart of perceptions and sensations, questioning and giving thought to what it means for a body to be inhabited by a speaking subject. Flying drones are only now appearing on the stage, opening an almost unprecedented field of experimentation and study. Live performance is in the process of forging closer ties with the world of robotics, bringing together very different epistemologies, synergizing know-how and forging partnerships that are often punctuated by artistic achievements. This work has been largely carried out in Japan (Paré 2016), at the HKU University of the Arts in Utrecht in the Netherlands, and at leading European art schools such as La Manufacture, Haute École des Arts de la Scène, in Lausanne, but to date no notable experiments have been carried out with an actor delivering a text.
