Our pals at Backyard Brains (makers of the terrific SpikerBox kit, which allows you to study the electrical impulses of insect neurons) are developing circuitry to control which direction a cockroach walks.
By modifying the HEXBug toy "Inchworm" circuitry to deliver pulses, we stimulated the antenna nerves of the discoid cockroach to "trick" the cockroach into turning upon command. Stay tuned! as we make the preparation easier, more reliable, and lighter!Working RoboRoach Prototype (Via Make)
