Afterand transformed into , here is the scariest version of the cyborg insect: the remote-controlled cockroach. Specifically, it is a Madagascar cockroach. In an article published in the journal a team of researchers details the method to take control of this insect thanks to a “bag to » solar.
The device is composed of a small support printed in 3D and glued to thecockroach. This holds the electronics, including an nRF24L01 wireless module and a 40mAh lithium-polymer battery, both connected to an Arduino Pro mini board. The battery is recharged using an ultra-thin organic solar cell of only 4 thick that produces 17.2 milliwatts of electrical power, glued to the cockroach.
Cyborg cockroaches controlled via Bluetooth
The solar cell is divided into strips, which allows it to deform and not interfere with thecockroach. Thanks to the small wireless module, they were able to control the insect via Bluetooth, without inserting in the body of the insect. They used electric directly on the , appendages at end of abdomen. Apply a on the left one, and the cockroach turns left, and vice versa.
This solution has proven to be particularly durable, since the device can stay stuck for an entire month. Once charged,works for about two hours. These are the communications that consume the most, and therefore the autonomy could be extended by optimizing them. Cockroaches being and photophobic, the researchers also suggested adding and . Thanks to an algorithm, the system could force the insect to stay under the to charge the battery.
