Poor Exhausted Littledog

This video of littledog doing some terrain navigaion excersizes is just hilarious. We really don’t have any technological updates since last time we mentioned him, but you should watch the video anyway. [Evan] at botjunkie pointed out how tired littledog must be to absolutely collapse at the end of each run. We started out thinking that his comment was humorous, but the bot is obviously going into a tidy configuration for carrying. As we watched, we saw that [Evan] seemed very correct. Littlebot completely collapses at the end of each run, toward the end of the video, it doesn’t even bother to fold up nicely, sprawling out in a very lifelike pose of utter exhaustion. We don’t know if this is intentional, but we think it should be.

Arduino Crib Rocker

Anyone with children will understand the value of this project immediately. This is an Arduino controlled sound activated crib rocker. [Lars] built a custom suspension system for his baby’s crib which allows a servo, mounted to the floor to rock it gently back and forth. Ok, maybe it’s a vigorous rocking, but that’s what some kids want. At least he’s safe and moderately immobile. He had to make a custom amplifier circuit to get his microphone working with the Arduino. It seems to all work perfectly now, triggering to begin rocking when it detects the baby’s cries. This should buy them a few extra minutes of sleep until the baby is truly hungry or annoyed. You can see a video of it in action and download the Arduino code on the project page.

Arduino Powered Delta Robot

We spotted this video of a delta robot today that seems to be powered by an Arduino. We were wondering when we would see this, happen. The source code is available on the project page. We really like the mouse control, its just fun to watch. You may recall that we recently covered some slightly more complex delta robots.

Programmable Spring Actuator Legs

This proof of concept shows an interesting way of making robotic legs. They are using programmable spring actuators to make these legs function as though they had a “reflex”. The builder pulls the robot along on a leash. As the leg reaches its limit of backward motion, a signal is sent from the shoulder down to the knee that lifts it, causing it to return to the forward position. A signal is also sent to the opposing shoulder to suppress the lift reflex, keeping them from both stepping at the same time. The resulting motion is very organic feeling. We’re curious how this could be implemented in a robot which moves under its own power.

I-Swarm Robot Update

I-Swarm_Micro_Robot_On_Thumb

Back in October we reported on the I-Swarm robotics project. [Travis] sent us some more information. These tiny robots are programmed optically and are able to respond to programming commands via an infrared signal. Locomotion is facilitated with piezoelectric actuators and the power to the units provided through a solar cell. It is not clear that this project is still ongoing as the I-Swarm web page lists a project termination date of 6/31/2008. That being said, the video embedded after the break was posted two days ago showing swarm movement and detailing the programming, testing, and hardware specifics.

Internet Enabled Furby

[edwindertien] sent us his project to connect a Furby to the internet. The original Furby controller was replaced with an Arduino which in turn was given ethernet connectivity via a LANTRONIX XPort serial ethernet module. This assigns the Furby an IP address which can then be accessed through a script or via a web interface. Now we want to see someone combine this idea with the arduino that sings “Daisy Bell” to make the ultimate in creepy new email notifiers.

Lego IPod Hacking Robot

The Linux4nano project has been working to port the Linux kernel onto the iPod Nano along with other iPods in general. Although the iPodLinux project has had luck with some older iPods, newer models protect firmware updates with encryption. One of the ways they plan on running code on the device is through a vulnerability in the notes program; it causes the processor to jump to a specific instruction and execute arbitrary code. To take advantage of this, they first need to figure out where their injected code ends up in the memory. Currently, they are testing every memory location by painstakingly loading in a bogus note and recording its effect. Each note takes about a minute to test and they have tens of thousands of addresses to check over several devices.
