@article { , title = {An energetically-autonomous robotic tadpole with single membrane stomach and tail}, abstract = {© Springer International Publishing Switzerland 2015. We present an energetically autonomous robotic tadpole that uses a single membrane component for both electrical energy generation and propulsive actuation. The coupling of this small bio-inspired power source to a bio-inspired actuator demonstrates the first generation design for an energetically autonomous swimming robot consisting of a single membrane. An ionic polymer metal composite (IPMC) with a Nafion polymer layer is demonstrated in a novel application as the ion exchange membrane and anode and cathode electrode of a microbial fuel cell (MFC), whilst being used concurrently as an artificial muscle tail. In contrast to previous work using stacked units for increased voltage, a single MFC with novel, 0.88ml anode chamber architecture is used to generate suitable voltages for driving artificial muscle actuation, with minimal step up. This shows the potential of the small forces generated by IPMCs for propulsion of a bio-energy source. The work demonstrates great potential for reducing the mass and complexity of bio-inspired autonomous robots. The performance of the IPMC as an ion exchange membrane is compared to two conventional ion exchange membranes, Nafion and cation exchange membrane (CEM). The MFC anode and cathode show increased resistance following inclusion within the MFC environment.}, doi = {10.1007/978-3-319-22979-9\_37}, eissn = {1611-3349}, issn = {0302-9743}, journal = {Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics)}, note = {Comments and Suggestions : The final publication is available at http://dx.doi.org/10.1007/978-3-319-22979-9\_37}, pages = {366-378}, publicationstatus = {Published}, publisher = {Springer Verlag}, url = {https://uwe-repository.worktribe.com/output/843993}, volume = {9222}, keyword = {Bristol Robotics Laboratory, energetic-autonomy, ionic polymer metal composite, microbial fuel cell, soft robots}, year = {2015}, author = {Philamore, Hemma and Rossiter, Jonathan and Ieropoulos, Ioannis} }
