JumpRoaCH is Kind Of Cute, Kind Of Creepy

There’s a theory that the fear of scurrying things is genetic. Likewise, a similar theory arose about the tendency for humans to find helpless things cute. After all, our useless babies do best in a pest free environment. This all could explain why we found this robotic roach to be both a little cute and a little creepy.

The university sponsored project, JumpRoaCH, is a collaboration between South Korea’s SNU Biorobotics Lab and Berkeley’s Biomimetic Millisystems Lab. Imitating insects has been a popular avenue for robotic research, and often results in very interesting experiments.

This robot looks like a ladybug going through its rebellious teen phase. It runs on six hook shaped legs which allow it to traverse a wider array of surfaces than wheels would, at the expense of speed and higher vibrations. The robot does a very convincing, if wobbly, scurry across the surface of its test table.

It also has a secret attack in the form of a single Rockem Sockem Robot arm located on its belly. With a powerful burst, the arm can launch the robot up a few feet to a higher surface. If the robot lands on its wheels the researchers high-five. If the robot lands on its back, it can use its ,”wings,” to flip itself right-side-up again.

The resulting paper (PDF file) has a nice description of the robot and its clever jumping mechanism. At least if these start multiplying like roaches, hackers will never short for tiny motors for their projects. Video after the break.

Build Your Swarm: Control Cockroaches for Under $30!

Have you ever wanted to control an army of cockroaches? We’ve all seen remote control cockroaches before — and they really are quite a fascinating specimen to work with — but did you know you can control one for about $30 worth of components, with a Arduino Micro?

It’s actually pretty simple. By stimulating a cockroaches antenna with variable frequencies (to mimic neural signals) you can convince the cockroach that they’ve hit a wall and should turn the other way. What results is a remote-controlled roach. How cool is that!

Cockroach pimps a sweet ride

This giant Madagascar hissing cockroach rides proudly atop his three-wheeled robotic platform. This project from several years ago is new to us and our reaction to the video after the break is mixed. We find ourselves creeped out, delighted, amazed, and saddened.

The cockroach controlled robot uses a trackball type input. A ping-pong ball is spun by a cockroach perched on top. The lucky or tortured (depending on how you look at it) little bug has an array of lights in front of it that illuminate when obstacles are in front of the robot. The roach’s natural aversion to light should make it move its legs away from that part of the display, thereby moving the robot away from the obstruction.

We’ve seen some bio-hacking in the past. There were robots that run off of rat brain cells and remote controlled beetles. But none of these projects make us want to get into this type of experimentation. How about you?

Fast little hexapods

We’ve posted many many times about hexapods. One of the most common comments, aside from how creepy they are, is about their speed. Hexapods are generally pretty slow. These little bots are quite a bit different though. The Sprawl and iSprawl, are anything but slow. Using a hybrid leg mechanism that aims its piston like “toes”, they mimic the motion of cockroaches. The video shows the speed can be pretty quick, especially the iSprawl in the second half. The leg mechanism the Sprawl is air powered, while the iSprawl uses a push/pull cable transmission system. As pointed out at BotJunkie, it’s nice for the “i” in iSprawl to actually mean something. It stands for “independent”.
