"RoboRoaches" Invade McCallie

Thursday, May 22, 2014

Students in Dr. Elizabeth Forrester’s AP Biology class at McCallie created a homegrown batch of the world’s first commercially available cyborg roaches, or “Robo Roaches,” as a way to better understand neural microstimulation.

After a week of neuroscience lectures, students put their knowledge to task as they were asked to perform surgery on cockroaches, implanting electrodes into the insect’s antennae that could then control the roaches’ movements via a smartphone app. 

Throughout the year, students learned that even though organisms appear very different at the cellular level, they share other similarities. The human nervous system is much more complex than that of a cockroach, but the structure and function of an individual’s neurons is very similar, allowing students to learn about the human brain via “Robo Roaches,” said officials.

The boys would first anesthetize the roaches in ice water. Then, through an 90-minute-long surgical procedure, they would cut a portion of the antennae and implant electrodes which would touch the insect’s nerves. After the roaches recovered overnight from surgery, the boys would then attach a Bluetooth backpack called a SpikerBox which would receive information from a smartphone app. This allowed the boys to send electrical impulses to the antennae, which in turn directed the movement of the roaches. 

Some of the experiments were more successful than others, which was also a part of the learning experience, according to Dr. Forrester.

She noted that “by testing the early prototypes, the boys are helping to generate data that will ultimately improve the technology.” Having tested the early cyborg prototypes, the boys helped to generate data that will improve the system so that it can be used practically for rescue in natural disasters. For example, she said, the roaches could eventually be equipped with cameras and sent into rubble in hopes of locating victims.

Do Something To Protect Our Children

It is unconscionable in this day and age that these children had to exist in such deplorable conditions and that an innocent baby suffered and died alone in a locked car.  Yes, there is blame and accountability considering this family had child neglect charges filed a few years ago (that were apparently dropped and expunged) and a large part of the responsibility should ...
