scientists iron out the bugs to harness cyborg - roaches for rescue work
the RIKEN Cluster for pioneering research [ CPR ] researchers have equipped the robotic insects with a tiny wireless control module that is powered by a rechargeable battery attached to a solar cell, allowing the cockroaches to roam freely for long periods of time.and wireless control of the leg segments has been one of the key challenges scientists have faced when developing cyber insects. moreover , in order for the devices to be used for monitoring purposes , it was fundamental that their batteries were long lasting , to ensure that the cockroaches would be under control at all times
the scientists at RIKEN overcame this challenge by fitting their cyborg insect with an ultrathin 0.004 mm thick organic solar cell module, which was mounted on the dorsal side of the insect's abdomen.
''Body-mounted energy-harvesting devices are criticale for expanding the range of activity and functionality of cyborg insect, ''DR kenjiro fukuda'' from the RIKRN cluster for pioneering research in japan, said
once these components were integrated into the cockroaches, along with wires that stimulate the leg segments, the new cyborgs were tested . the battery was charged with pseudo-sunlight for 30 minutes , and animals were made to turn left and right using the wireless remote control.
''considering the deformation of the thorax and abdomen during basic locomotion , a hybrid electronic system of rigid and flexible elements in the thorax and ultra soft devices in the abdomen appears to be an effective design for cyborg cockroaches , ''says fukuda. ''moreover , since abdominal deformation is not unique to cockroaches, our strategy can be adapted to other insect like beetles, or perhaps even flying insect like cicadas in the future.''
