Autonomous Underwater Biorobots: A Wireless System for Power Transfer

Reduction of eddy current losses in inductive transmission systems with ferrite sheets

“…The concept is based on inductively coupled coils that allow the simultaneous transfer of power and information. Typical examples can be found, e.g., in non-contact battery chargers for modern cell phones [1] or electric vehicles [2, 3], in the field of robotics [4, 5], RFID systems [6, 7], or wireless sensor networks [8, 9]. In addition, inductive links are used in a variety of biomedical applications for the power and/or information transfer of implanted medical systems, e.g., cochlear implants [10–12].…”

An Autonomous Charging System for a Robotic Fish

“…In the realm of biologically-inspired robotic fish that mimic complex locomotory patterns of live fish [16][17][18][19][20][21][22][23][24], the problem of autonomous charging is yet to be fully addressed [25][26][27][28][29]. Beyond laboratory [30][31][32] and field [33,34] applications requiring long-term deployment for animal behavior studies and environmental mapping, autonomous charging can greatly enhance informal science exhibits of robotic fish [26,29].…”

“…A semiautonomous solution was proposed in [26,27], where the robotic fish was programmed to autonomously swim toward a designated portion of the tank when the battery was low, so that a human operator could manually connect the robot to a charging station. Wireless charging of a robotic lamprey from its head was theoretically proposed in [25]. However, its application constrains the mechanical design to cylindrically shaped robots, and thus necessitates overcoming tight tolerances between the inductive coils [25].…”

“…Wireless charging of a robotic lamprey from its head was theoretically proposed in [25]. However, its application constrains the mechanical design to cylindrically shaped robots, and thus necessitates overcoming tight tolerances between the inductive coils [25]. Interestingly, a robotic fish powered through wireless magnetic resonance has been recently developed, yet the robot can only swim in specially outfitted 30 cm diameter tanks [28].…”

Evolutionary multi-objective optimization of H<inf>&#x221E;</inf> controller for inductive power transfer system

“…The energy transfer process is unaffected by dirt, water, and harsh environments, and it is extremely safe and reliable. In the last decade, the technology gets more and more applications in Electrical Vehicle (EV), industrial moving vehicle and digital electronics devices [1][2][3].…”
