There are many people who find being around insects uncomfortable. This is understandable, and only likely to get worse as technology gives these multi-legged critters augmented bodies to roam around with. [tech_support], for one, welcomes our new arthropod overlords, and has even built them a sweet new ride to get around in.
The build follows the usual hallmarks of a self-balancing bot, with a couple of interesting twists. There’s twin brushed motors for drive, an an Arduino Uno running the show. Instead of the more usual pedestrian IMUs however, this rig employs the Bosch BNO055 Absolute Orientation Sensor. This combines a magnetometer, gyroscope, and accelerometer all on a single die, and handles all the complicated sensor fusion maths onboard. This allows it to output simpler and more readily usable orientation data.
The real party piece is even more interesting, however. Rather than radio control or a line following algorithm, this self-balancer instead gets its very own insect pilot. The insect is placed in a small chamber with ultrasonic sensors used to determine its position. The insect may then control the movement of the bot by moving around this chamber itself. The team have even developed a variety of codes to dial in the sensor system for different types of insect.
It’s not the first time we’ve seen insects augmented with robotic hardware, and we doubt it will be the last. If you’re working on a mad science project of your own, drop us a line. Video after the break.

Some legged robots end up moving with ponderous deliberation, or wavering in unstable-looking jerks. A few unfortunates manage to do both at once. [MusaW]’s 3D Printed Quadruped Robot, on the other hand, moves in rapid motions that manage to look sharp and insect-like instead of unstable. Based on an earlier design he made for a 3D printable quadruped frame, [MusaW] has now released this step-by-step guide for building your own version. All that’s needed is the STL files and roughly $50 in parts from the usual Chinese resellers to have the makings of a great weekend project.
The robot uses twelve SG90 servos and an Arduino nano with a servo driver board to control them all, but there’s one additional feature: Wi-Fi control is provided thanks to a Wemos D1 Mini (which uses an ESP-8266EX) acting as a wireless access point to serve up a simple web interface through which the robot can be controlled with any web browser.
Embedded below is a brief video. The first half is assembly, and the second half demonstrates the robot’s fast, sharp movements.

You’ve probably heard of micro-drones, perhaps even nano-drones, but there research institutions that shrink these machines down to the size of insects. Leading from the [Wiss Institute For Biologically Inspired Engineering] at Harvard University, a team of researchers have developed a miniscule robot that — after a quick dip — literally explodes out of the water.
To assist with the take off, RoboBee has four buoyant outriggers to keep it near the water’s surface as it uses electrolysis to brew oxyhydrogen in its gas chamber. Once enough of the combustible gas has accumulated — pushing the robot’s wings out of the water in the process– a sparker ignites the fuel, thrusting it into the air. As yet, the drone has difficulty remaining in the air after this aquatic takeoff, but we’re excited to see that change soon.
Looking like a cross between a water strider and a bee, the team suggest this latest version of the RoboBee series — a previous iteration used electrostatic adhesion to stick to walls — could be used for search and rescue, environmental monitoring, and biological studies. The capacity to transition from aerial surveyor, to underwater explorer and back again would be incredibly useful, but in such a small package, it is troublesome at best. Hence the explosions.

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.

If you watch science fiction movies, the robots of the future look like us. The truth is, though, many tasks go better when robots don’t look like us. Sometimes they are unique to a particular job or sometimes it is useful to draw inspiration from something other than a human being. One professor at Johns Hopkins along with some students decided to look at spider crickets as an inspiration for a new breed of jumping robots.

It’s name is Blaberus Cranifer, or Death’s Head for short. Light has now been shed on this once secret project built by the Immanuel Kant Baltic Federal University for a “vague” Russian organization. The little guy has a 20 minute battery life and can carry a 10 gram payload. Which comes in handy when you want to sneak a camera into hard to reach places. Other requirements were for it to look and behave like a real live insect.
It’s an impressive project considering it was built from scratch in only seven months time. Its intricate gears and other mechanical features would require the hands of a skilled watch maker to construct. Alternatively, one can control live insects such as controlling a roach’s brain or hooking up some radio controls to a live beetle. But building robotic insects is still pretty cool.
Be sure to check out the well made video detailing some of the project’s build process.

Producing micro robotics is not yet easy or cost-effective, but why do we need to when we can just control the minds of cockroaches? A team or researchers from North Carolina State University is calling this augmented Madagascar Hissing cockroach an Insect Biobot in their latest research paper (PDF). It’s not the first time the subject has come up. There have already been proofs in research and even more amateur endeavors. But the accuracy and control seen in the video after the break is beyond compare.
The roach is being controlled to perfectly follow a line on the floor. One of the things that makes this iteration work so well is that the microcontroller includes a new type of ADC-based feedback loop for the stimulation of the insect brain. This helps to ensure that the roach will not grow accustom to the stimulation and stop responding to it. Since this variety of insect can live for about two years, this breakthrough makes it into a reusable tool. We’re not sure what that tool will be used for, but perhaps the next plague of insects will be controlled by man, and not mother nature.
