[DJ Sures], who built the autonomous Wall-E, is back with another creation. His new autonomous Cookie Monster is certainly an interesting build. He had the cookie monster plush toy already so the first step was to flay the blue beast and insert a skeleton. He used another robot for that. There are two servos for the wheels plus one for each arm and one for the neck. There’s a distance sensor in the mouth. He built a custom board for the PIC18F4685 microcontroller which is running the same 2D mapping code as his previous bot. Check out the video of it in action below.

Swarming Robot Ants
European researchers in the I-SWARM project are hard at work developing small, autonomous robots that can work together and communicate to perform different functions. They successfully built two types of robots: the I-SWARM, and the Jasmine robots. The I-SWARM robots are three millimeters in size, are powered by a solar cell, and move by vibration. The Jasmine robots are the size of two-Euro coins, have small wheels, and are powered by battery. These tiny robots have several advantages over their bulky predecessors, such as high redundancy, greater flexibility, and the ability to manage tough terrain. They could even be used to repair larger robots. They also come with distinct challenges. Because of their minuscule size, programming memory is necessarily limited, and the team had to come up with special algorithms to manage and control the machines. Though they haven’t been able to meet their goal of making a thousand of them, the researchers are hopeful and confident about their abilities to mass produce the robots cheaply.

Autonomous Wall-E
[djsures] went crazy on his Interactive Wall-E toy. Wall-E just didn’t have enough bounce in his step, so [djsures] decided to give him an overhaul. He went through the entire robot and replaced most of the joints with servos, giving much more control and adding head tilt. All of this was wired to a microcontroller housed in Wall-E’s body. The distance sensor was mounted in Wall-E’s neck, so when he turns his head, he’s actually surveying his surroundings. Check out the video after the break.
ArduPilot Pro Autonomous Drone
We wrote about [Chris Anderson] before when he released the Arduino based autopilot. He has since crashed his first Predator UAV, due to an underpowered motor and poor control of the v-tail only steering. He has since released a pro version of the autopilot controller, and is modifying this UAV Predator drone kit to work with it. One ATMega168 processor handles flying and the other handles GPS navigation, but because they work together, it results in a fully autonomous drone. He also has a BlimpDuino version we have covered before.
Autonomous Hovering Drones Invade Germany
We welcome the swarm of autonomous hovering robot overlords being made by students at Humboldt University. The goal of this project is to build an autonomous hovering platform that is controlled via adapted insect behavior. Navigation comes from monitoring real time inputs, such as air pressure and optical sensors, not by predefined paths and GPS coordinates. Some examples of this adapted behavior are: navigation via polarized sun light like African ants, and optical flow similar to bees.
You can see the platforms in action on Spiegel Online, but unless you understand German, you won’t get much else out of it.
If any of this seems familiar, it’s because we covered CCCamp 2007, which was near Berlin and had some very similar quadcopters. While the large quadcopter platforms have been around for a while and are steadily coming down in price, there are some new alternatives out there that are quite tempting. Anyone want to build some autonomy into this little baby?

UAV Medical Couriers
We’re skeptical about most technology that’s designed to help remote villages (yes, even that one), but these new UAV medical couriers look like a great idea. The turn around time for medical sample analysis in remote South African villages can be excruciating. A team of engineers have attempted to adapt two different unmanned aerial vehicles for transport of medical samples. These could be either blood or saliva that needs testing. Test results would be relayed via phone as they are now, but the initial transport time would be much faster. The larger of the two UAVs can carry up to 500g; that’s enough to haul two units of blood for transfusion. The UAVs can be launched by hand and can survive winds up to 45kph. They fly their preprogrammed routes autonomously and don’t require any operator intervention. The team has flown two successful trials and is waiting for approval from the South African Civil Aviation Authority. For safety, they’re only transporting samples that can be sterilized before flight. New Scientist has a short video after the break. Continue reading “UAV Medical Couriers”
Autonomous Paintball Sentry Gun
[Alan] pointed out this great commercial paintball sentry gun. The gun has a low power motherboard running Ubuntu connected to a firewire camera. Two high torque motors control the pan and tilt of a Tippman 98 custom. The control box allows for easy setup. You can change the sensitivity, color tracking, and firing modes. It also has a remote kill switch. All around a nice looking machine, but at $3K we doubt many of you will be buying one. Beta test video embedded after the break.
