Dextre Heralds a New Age in Robotics

Dextre the ISS's new space robot 

During the second spacewalk of the STS-123 mission, the crew began assembling Dextre.  Dextre is the newest member of the International Space Station’s Mobile Servicing System, and will act as a repair and construction robot for the ISS’s exterior.  Dextre is enormous “standing” or rather floating at 12 feet tall.  He has an 8 foot shoulder space and two 11 foot arms!

From National Geographic News, Astronaut Garrett Reisman stated,

“Now I wouldn’t go as far to say that we’re worried it’s going to go run amok and take over the space station or turn evil or anything because we all know how it’s operated and it doesn’t have a lot of its own intelligence,” Reisman told the Associated Press last week.

“But I’ll tell you something,” Reisman said. “He’s enormous, and to see him with his giant arms, it is a little scary. It’s a little monstrous, it is.”

Dextre is provided by the Canada Space Agency, who has for years supported the robotic arm on the shuttle.

Matlab Package for LEGO Mindstorms

I recently received a comment on my post on controlling NXT robots with Matlab that pointed me to the RWTH – Mindstorms NXT Toolbox for MATLAB®, which is a public domain Matlab package that enables one to interface with and control LEGO mindstorms.

The RWTH – Mindstorms NXT Toolbox for MATLAB® was developed as a student project in the Institute of Imaging and Computer Vision at RWTH Aachen University in Aachen Germany.  It provides a Matlab interface with the NXT brick that includes Bluetooth communication, sensor interface and motor interface.  It requires a working Matlab license, of course. 

The package is very easy to set up.  It took me less than ten minutes to successfully test the example programs over Bluetooth.

There are some very nice motor features, such as motor synchronization and speed ramp-up and ramp-down.

I have yet to explore how easy it is to modify or extend the code, but it ought to be a straightforward matter.

The package can be downloaded from

Old Glory Robot Insurance

 Robot Eating Old Person's Medicine

Do you have robot insurance?

Consider Old Glory Robot Insurance, because when they grab you with their metal claws, you can’t break free.  Because they are made of metal, and robots are strong.

Robotic Toddler? WHY???

Tonight on the Colbert Report, I learned of a Japanese research project to make a robotic toddler.  I am sorry, but not only am I not at all sure why one would endeavor to do this, but I am also not sure why one would choose this particular design.

With all due respect to the researchers involved, I can only say that this is creepy at best and terrifying at worst.  I must voice my appeal:

Please reconsider using your powers for good instead of evil!

Just because something can be done, does not mean that it should be done.  Plus, who ever heard of a toddler that is 4 feet tall and weighs over 70 pounds, and is connected to a pneumatic device for power?

This post definitely goes under the category titled “Seriously???”

Walking LEGO Machines

Walking LEGO Machine 

On Philippe ”Philo” Hurbain’s LEGO site, I found these amazing 8-legged LEGO walkers.  Here you can find a movie of this walker… its very impressive!

These are designed after Theo Jansen‘s amazing walking kinetic sculptures that are powered by wind or solar power. Here are some great videos of these Theo Jansen’s kinetic sculptures.

Here are two computer graphics studies of Theo Jansen’s mechanism.

Enjoy,
