Radio-Controlled Cockroaches – The New Biobots


Radio-controlled cockroaches maybe among the worst of your nightmares, as there are at least four species that like to hang out with us in our homes. They are quiet neighbors and will run off and hide if they think we’re watching them. They are hardy little beasts and undemanding in diet. However, they are not your everyday pet choice with perhaps the exception of the hissing variety which come from Madagascar and can eat rotting wood, fruit etc.

They are very good at getting into crevices and small places in general and are quite happy moving around in the dark. Discovery News reports out on a paper presented at the IEEE conference in San Diego (1) on the latest biobot. A more detailed report and a video are available from Shipman’s report in PhysOrg. News from N.C. State U (2).

In their lab, Latif and Bozkurt fitted out some hissing cockroaches with a radio receiver in a personalized backpack. The radio was wired up to a controller attached to either antenna to steer the beastie.

Charge up an antennae and your roach thinks it has hit a wall and will move away, so with judicious, but shocking behavior on the roach-pilot’s part, your favorite pet may be steered along a course.

In case they got lazy, electronic spurs were connected to the abdominal organs that sense air movement. The electric sensation gives your roach the feeling that something big that eats roach burger is coming and it hurries off.

The BIG question is why do we want radio-controlled cockroaches in the first place? Why accept the challenge? Because it’s there. Then once you have them wandering about ideas come pouring forth. Send them into collapsed building with sensors top detect trapped people is one suggested in the reports.

There is another possibility that is much more likely to appeal to the general public. There is just time to get the production lines going for the Holiday Season. Sell small groups with a controller that can be run from an iPhone or Android app so people can have races around the carpet.

If this catches on and people get skilled, I can visualize large public meetings with big prizes for the fastest roach and most skilled pilot. It could replace pool tables and dart boards in pubs and bars. Much cheaper to keep, feed and transport than a thoroughbred horse.

Life And Death Issues


Life and death issues always get our complete attention. We worry about why someone dies suddenly, could it be our turn next? Are we seeing the start of a pandemic or is there something bad in the drinking water? Whatever the reason, we want to know why. We want an autopsy and the coroner to sign off on the report so we can take appropriate action.

 In addition, we may want to mourn our loss or express our sympathy to others. Humans are not unique in this respect. It’s no surprise that non-human primates react to the death of a close relative, but the empathy goes wider. Whales and dolphins can be very supportive, giraffes  (1) and elephants (2) show great concern over the loss of an offspring.

It is easy to accept that mammals in general are sensitive creatures as we are of the same taxa. It might not help to ponder on that too deeply if we have the body parts on our dinner plate.

We are also “discovering” that birds are very intelligent, so it should come as no surprise that they too get concerned over life and death issues when they raise their ugly head within their group. The Western scrub-jay is the latest to have their concerns discussed. Iglesias et al from UC Davis have documented their behavior recently (3, 4), and carried out an experimental program to clarify their views when it comes to finding one of their flock dead on the ground.

What happens is that the call goes out for the locals to gather and make note of what has happened. The calls include the alarm calls that they use when there are predatory thugs like Horned Owls around and they go off their foraging program for a day or so. They get back to foraging normally in a couple of days as they assume the danger has past.

They ignore imitation dead jays. They know when they are looking at the real thing. A stuffed dead jay is not considered to be a life and death issue. How much of the concern is for the deceased and how much is for the potential danger that they may be in is not clear, but the thought that it could be me next is clearly a top priority as they go through their ritual.
