From CLEANINGFISH to Gillbert

A student at the University of Surrey proposed a fish-like robot called Gillbert in the context of a university robotics contest, suggesting a system that could move through water and capture microplastics using a gill-inspired filter. The concept was subsequently developed into a 3D-printed research prototype by a university team. The robot mimics fish locomotion via a flexible tail and is designed to collect particles of up to around 2 mm, primarily for monitoring and experimental purposes rather than large-scale cleanup. The project was published as open source. The idea follows earlier conceptual work such as the CLEANINGFISH design study by Prof. Dr. Oliver Bendel (2014), which envisioned small robotic fish operating individually or in swarms to remove plastic and debris from aquatic environments and transport it to collection points, including objects located on the ground. This concept was further examined in 2015 within a project at the University of Applied Sciences and Arts Northwestern Switzerland (FHNW), where increasing plastic pollution in seemingly clean waters and its ecological and human impact were analyzed. Oliver Bendel and his student concluded that robotic fish could interfere with aquatic life and were not sufficiently efficient for practical large-scale deployment, while also raising questions in machine and technology ethics. Gillbert can be understood as a contemporary experimental continuation of these earlier ideas under improved technological and collaborative conditions.

Fundamentals of Animal-Machine Interaction

“Just.Us + Animal Welfare” is a lecture series organized by Department 10 Veterinary Medicine to promote animal welfare at Justus Liebig University Giessen. On November 12, 2025, Prof. Dr. Oliver Bendel gave a lecture on “Bao meets Pluto: Grundlagen und Beispiele der Tier-Maschine-Interaktion” (“Bao meets Pluto: Fundamentals and examples of animal-machine interaction”). Animal-machine interaction deals with the encounter and coexistence of animals and machines – from classic devices to vehicles, aircraft, and agricultural machinery to networked, autonomous robots and AI systems. The focus is on perception through sensors and senses, interaction and communication between animals and machines, and the question of how these encounters can be designed technically, organizationally, and ethically in such a way that risks for animals are reduced and potential for them and for humans is tapped. In his lecture, Oliver Bendel laid out the fundamentals of animal-machine interaction and described prototypes and projects. He also outlined what is possible and to be expected in this field of research in the coming years, for example in connection with robotic quadrupeds and bipeds. The online lecture was followed by 660 listeners. Further information is available at www.uni-giessen.de/de/fbz/zentren/icar3r/akademie/justus.

The Robodog Project is Done

“The Robodog Project: Bao Meets Pluto” examined how domestic dogs respond to the Unitree Go2 quadruped robot – nicknamed Bao by project initiator Prof. Dr. Oliver Bendel – and how their owners perceive such robots in shared public spaces. The project began in late March 2025 and was completed in early August 2025. The study addressed three questions: (1) How do dogs behaviorally respond to a quadruped robot across six conditions: stationary, walking, and jumping without an additional dog head, and stationary, walking, and jumping with an additional 3D-printed dog head? (2) What are owners’ expectations and concerns? (3) What regulatory frameworks could support safe integration? Twelve dogs were observed in six structured interaction phases; their behavior was video-coded using BORIS.Another dog participated in a preliminary test but not in the actual study. Pre-exposure interviews with eight owners, as well as an expert interview with a biologist and dog trainer, provided additional insights. Led by Selina Rohr, the study found most dogs were cautious but not aggressive. Curiosity increased during robot movement, while visual modifications had little impact. However, a 3D-printed dog head seemed to interest the dogs quite a bit when the robot was in standing mode. Dogs often sought guidance from their owners, underlining the role of human mediation. Owners were cautiously open but emphasized concerns around safety, unpredictability, and liability. The findings support drone-like regulation for robot use in public spaces.

When Animals and Robots Meet

The volume “Animals, Ethics, and Engineering: Intersections and Implications”, edited by Rosalyn W. Berne, was published on 7 August 2025. The authors include Clara Mancini, Fiona French, Abraham Gibson, Nic Carey, Kurt Reymers, and Oliver Bendel. The title of Oliver Bendel’s contribution is “An Investigation into the Encounter Between Social Robots and Animals”. The abstract reads: “Increasingly, social robots and certain service robots encounter, whether this is planned or not, domestic, farm, or wild animals. They react differently, some interested, some disinterested, some lethargic, some panicked. Research needs to turn more to animal-robot relationships, and to work with engineers to design these relationships in ways that promote animal welfare and reduce animal suffering. This chapter is about social robots that are designed for animals, but also those that – for different, rather unpredictable reasons – meet, interact, and communicate with animals. It also considers animal-friendly machines that have emerged in the context of machine ethics. In the discussion section, the author explores the question of which of the presented robots are to be understood as social robots and what their differences are in their purpose and in their relationship to animals. In addition, social and ethical aspects are addressed.” The book was produced by Jenny Publishing and can be ordered via online stores.

When the Robodog is Barked at

Animal-machine interaction (AMI) is a discipline or field of work that deals with the interaction between animals and machines. This is how Prof. Dr. Oliver Bendel explains it in the Gabler Wirtschaftslexikon. It is primarily concerned with the design, evaluation, and implementation of complex machines and computer systems with which animals interact and which in turn interact and communicate with animals. There are close links to animal-computer interaction (ACI). Increasingly, the machine is a robot that is either remote-controlled or (partially) autonomous. In “The Robodog Project” (also known as “Bao Meets Pluto“), the encounters between robotic quadrupeds and small to medium-sized dogs are explored. The project collaborator is Selinar Rohr, who is writing her bachelor’s thesis in this context. The walking, running, and jumping Unitree Go2 from Oliver Bendel’s private Social Robots Lab is in its original state or is wearing a head made with a 3D printer provided by Norman Eskera. The project is being carried out at the FHNW School of Business and will end on August 12, 2025, after which the results will be presented to the community and, if possible, to the general public.

The Robodog Project

Robotic quadrupeds – often referred to as robot dogs – are becoming more and more widespread. As a result, they will increasingly encounter real dogs. The question is how to design and construct the robot in such a way that the animals do not overreact and neither robots nor animals or bystanders are harmed in any way. As part of “The Robodog Project”, smaller dogs are to be confronted with the walking, running and jumping Unitree Go2 from Prof. Dr. Oliver Bendel’s private Social Robots Lab. The plan is to visit controllable environments such as dog training grounds and arrange meetings and discussions with dog owners. The results will lead to suggestions for design and control. Robot enhancement can also play a role. For example, robot enthusiasts have used a 3D printer to produce cartoonish heads for the Unitree Go2, giving it a completely different look. The project – also known as “Bao Meets Pluto” after the pet name of the robotic four-legged friend and the Disney character – was launched at the FHNW School of Business at the end of March 2025. It is part of Oliver Bendel’s research in the field of animal-machine interaction (AMI). Selina Rohr, who is writing her Bachelor’s thesis on the topic, has been recruited as a member of the team. She met Bao at a get-together at the end of April 2025 and let it run and jump around the room.

The Robodog Project Starts

Robotic four-legged friends – often referred to as robot dogs – are becoming more and more widespread. As a result, they will also encounter more and more real dogs. The question is how to design, control, and program the robot in such a way that the animals do not overreact and cause no harm to robots, animals, or bystanders. As part of “The Robodog Project”, smaller dogs are to be confronted with a walking, running, and jumping Unitree Go2. The plan is to visit controllable environments such as dog training grounds and arrange meetings with dog owners. The findings will lead to suggestions for design and control. Robot enhancement can also play a role here. For example, hobbyists have produced heads for Unitree Go2 using a 3D printer, giving the robot a completely different look. Suggestions for programming will also be made. The project is due to start at the FHNW School of Business in March 2024. It is part of Prof. Dr. Oliver Bendel’s research in the field of animal-machine interaction.

13 Animal-Related Concepts and Artifacts

Since 2012, Oliver Bendel has developed 13 concepts and artifacts in the field of animal-computer interaction (ACI) or animal-machine interaction (AMI) together with his students. They can be divided into three categories. The first are animal- and nature-friendly concepts. The second are animal-friendly machines and systems (i.e., forms of moral machines). The third are animal-inspired machines and systems that replace the animals or bring them closer to you. Articles and book chapters have been published on many of the projects. The names of the developers can be found in these. A few prototypes made it into the media, such as LADYBIRD and HAPPY HEDGEHOG. Oliver Bendel repeatedly refers to Clara Mancini, the pioneer in the field of animal-computer interaction. Recently, ethicists such as Peter Singer have also turned their attention to the topic.
