Yes—researchers have used electrical stimulation and wireless electronics to guide cockroaches, including systems that trigger turns, steer locomotion, or let an operator guide a camera-equipped insect. These are research prototypes, not devices that take over a cockroach’s whole behavior. The headline describes several related projects, not one chip that controls every movement.
What “remote-controlled” means in these experiments
The systems send electrical signals to selected parts of an insect’s nervous system or movement pathways. Depending on the prototype, a signal can prompt a left or right turn or guide locomotion. The cockroach still supplies its own biological movement; the electronics provide limited directional input rather than unrestricted control.
“Chip in the brain” is also misleading. The studies described here use stimulators and electrodes aimed at peripheral targets such as antenna nerves or leg-control pathways, alongside electronics carried on the insect’s body. The cited work does not establish that a single brain implant gives an operator control over the animal’s full range of behavior.
Three different approaches
The projects share the idea of electronically guiding a living insect, but differ in how the operator sends commands, what equipment the cockroach carries, and whether the operator receives visual feedback.

The project framed the camera-equipped system as a possible tool for exploration and search-and-rescue scenarios. |
How electrical stimulation makes a cockroach turn
In the 2016 brain-computer-interface route, the human operator looked at visual stimuli while an EEG system decoded a movement intention. A Bluetooth command then activated a portable microstimulator. The resulting electrical pulse train stimulated an antenna nerve and produced a commanded turn. This is a chain of distinct steps—human signal, decoding, wireless command, nerve stimulation—not a wireless connection directly into the cockroach’s brain.
Other systems use different control arrangements. RIKEN’s platform sent wireless signals to a leg-control module to guide locomotion. CameraRoach paired joystick input with neural stimulation, allowing its operator to steer while viewing images transmitted over Wi-Fi. These approaches should not be treated as interchangeable: they have different stimulation targets and payloads, and the cited descriptions do not specify every electrode target in the same detail.

What the solar-rechargeable backpack adds
RIKEN’s 2022 prototype addressed a practical limitation of carrying electronics: the insect’s body moves and deforms as it walks. The system placed relatively rigid electronics and a lithium-polymer battery in a 3D-printed elastic backpack on the thorax, while an ultrathin organic solar cell was attached to the abdomen. The cell charged the battery under simulated sunlight; it was not described as eliminating the battery.
The peer-reviewed paper identifies the insect as a Madagascar hissing cockroach, Gromphadorhina portentosa. It reports a solar-cell thickness of 4 micrometres and an output of 17.2 mW for the body-mounted module. RIKEN reported that the backpack remained stably mounted for more than one month. Those figures describe this research platform and its reported conditions, not a general performance guarantee for other insects or designs.

“Considering the deformation of the thorax and abdomen during basic locomotion, a hybrid electronic system of rigid and flexible elements in the thorax and ultrasoft devices in the abdomen appears to be an effective design for cyborg cockroaches.”
How reliable is the control?
One figure from Li and Zhang’s 2016 work is easy to overstate. Their PLOS-linked brain-computer-interface chapter reports average success rates above 85% for single human-BCI and cyborg reactions. In the same work, walking along preset tracks had only a 20% success rate. These results concern different tasks; the higher figure should not be read as an overall reliability rate, a guarantee of accurate navigation, or evidence that the insect can be directed through an arbitrary route.

The distinction matters in practice. A system may reliably prompt a particular reaction in a controlled task without reliably navigating obstacles, reaching a destination, or responding predictably across settings. The cited demonstrations support limited commands and guided movement, not dependable autonomous or remote navigation in unpredictable environments.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Could cockroach robots help in search and rescue?
They are a proposed research direction, not a demonstrated replacement for conventional search-and-rescue equipment. CameraRoach explicitly presents its camera-equipped cockroach in the context of search and rescue, while RIKEN describes inspection of environments and dangerous areas as potential applications. A small insect carrying a camera could, in principle, enter spaces that are difficult for larger machines to reach. But a research demonstration does not by itself establish field readiness, reliable operation in disaster conditions, or an ability to locate survivors.

The projects are also at different levels of capability. CameraRoach includes a camera and live Wi-Fi image transmission; the RIKEN platform focuses on wireless locomotion control and battery recharging; the BCI work demonstrates a human-intention-to-stimulation control path. None of those distinctions should be collapsed into a claim that every system can both navigate autonomously and provide a live view.
Can you buy or build one?
No current consumer product equivalent to these research systems is established by the available information. Historical RoboRoach educational-kit documentation exists, but that does not verify a current listing or show that the kit reproduces the RIKEN or CameraRoach experiments. The cited prototypes use custom stimulation electronics, control systems, and—in some cases—purpose-built wearable hardware. Ordinary robotics components alone do not recreate them.
Building a system that stimulates a living animal also raises animal-welfare and experimental-design concerns beyond ordinary hobby electronics. Anyone considering such work should consult relevant institutional and local requirements and avoid treating a published demonstration as a safe, ready-to-follow construction guide.
