An international team of scientists has created a device that allows them to be remotely controlled.
The control modules were fitted to the backs of the roaches, which can grow up to 2 inches long.
By stimulating each of the roaches' cerci, which are appendages that act like sensory nerves, the scientists were able to tell them where to go.
The new ones have a number of innovations that allowed them to assume control for longer periods of time.
The researchers were able to remote control the roaches for extended periods of time thanks to a tiny solar cell that kept the battery charged.
The power output of the ultrathin organic solar cell module is more than 50 times that of current state-of-the-art energy harvesting devices on living insects.
The roaches are not being dispatched during search and rescue missions.
Fukuda said it's not enough to prepare an application such as urban rescue because the current system only has a wireless locomotion control system. We can use our insects for such purposes if we integrate other required devices.
The same technology could be used to treat beetles and cicadas.
An army of insects that can be remotely controlled are a fun and futuristic vision.
