AVR Controlled Rubik’s Cube Solver

[Andrius] just sent in his robot Rubik’s cube solver. It isn’t as fast as the solver we saw last year but it also doesn’t require as many parts either. This project utilizes two claws, each actuated by just two servo motors. The thinking is done by a PC which calculates the necessary moves to solve the cube. Each instruction is then passed via USB to the AVR ATmega16 microcontroller that is responsible for the servo operation.

Right now it looks like the colors for each starting face have to be entered manually before a solution is calculated. We think [Andrius] is probably planning to upgrade this with the next generation of his software as he already has a webcam setup for this type of analysis.

Exoskeleton Rental Now Available

The HAL two-leg exoskeleton is now available for rent in Tokyo for $2300 per month. We saw the HAL in our power suit roundup from last year. There is footage of this lower-extremity suit demonstrated by three people. The video is a bit creepy because the they are apparently just out for a stroll in the city.

We really do want to see this succeed. Every time another advancement in exoskeletons comes around we glimpse the future of mobility and freedom for victims of paralysis. The machine is controlled via an interface that picks up electrical impulses on the surface of the skin. The built in battery provides power for up to five hours of operation before recharging is necessary.

The Old Robots Website

We found The Old Robots Website this morning and ended up spending way too much time there. It’s a display of mainly consumer robots, though there are some custom jobs tossed in there too. Ranging from silly to awesome and everywhere in between, we found tons of great information. By strange coincidence, we saw Arok in a documentary about eclectic homes last night. Arok’s creator explained that not only is he an amazingly versatile robot, Arok is also going to be the medium for communication after his creators death. That makes him even creepier.

S.P.A.R.K. Beginer Robotics Resources

We love to see educational resources appear. iRobot has put together Starter Programs for Advancement of Robotics Knowledge or S.P.A.R.K to serve as not only education, but amusement with the purpose of getting people interested in robotics. With sections divided into different grade levels, it is obvious that this is mainly meant for school aged kids. There are some games as well to keep them amused when they need a break. We looked around a little bit and it seems that they are still fleshing it out. We hope to see some structured content specifically created for education of youngsters. Right now it is mainly links to other resources.

Hand Of Man Mechanical Claw

September 8, 2009 by James Munns 30 Comments

[Christian Ristow], a former Muppet creator, has created a much larger puppet that has caught the attention of Popular Mechanics. His Hand of Man is a 27 foot long remote control mechanical claw. Powered by a 90 hp diesel engine, the hydraulic system can be controlled by a glove worn by the operator. This started as a demonstration for a robotics fair, but has recently made appearances at Burning Man, Maker Faire, and had the Grand Champions seat of Popular Mechanic’s Backyard Geniuses Award. While not as practical as some robotic human augmentations, it can crush a car. [Christian] is even allowing anyone who is interested at these events to pick things up and crush them at their own whim.

Various promo videos after the jump.

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

DSC00102_rocker01 (Custom)

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.
