"We demonstrated the remote control of insects in free flight via an implantable radio-equipped miniature neural stimulating system. [...] Flight initiation, cessation and elevation control were accomplished through neural stimulus of the brain which elicited, suppressed or modulated wing oscillation. Turns were triggered through the direct muscular stimulus of either of the basalar muscles. We characterized the response times, success rates, and free-flight trajectories elicited by our neural control systems in remotely-controlled beetles. We believe this type of technology will open the door to in-flight perturbation and recording of insect flight responses." (Link)
Here's some accompanying YouTube footage.
On the technical side, this seems rather straight forward (off-the-shelf components like a TI MSP430 MCU and a CC2431 transceiver are used). However, I don't know whether I should find the whole thing disgusting or cool."
