Hayabusa Nearing Itokawa

 

Hayabusa Mission

The Japanese mission to land a 10cm high robot names ‘Minerva’ on an asteroid is still on track even if the spacecraft is not in the best of health. Three of its four reaction wheels (devices used to maintain correct orientation) have failed and is now using precious propellant to stay on target.

The images that are being sent back are stunning. The survey of asteroid Itokawa is sure to produce a wealth of data on solar objects.

I’m looking forward to seeing if the tiny rover will be able to stay on the surface for any length of time or if it will bounce off and float away. If everything works as planned this will be the fist controlled landing and exploration of an asteroid in the history of mankind.

Karakuri the tea Robot

This Japanese tea serving robot showed up on a few places on the ‘net today. I have long wondered if anyone would ever offer one of these in kit form and now I have my answer.
You can get one from the Robotstore for $90US ($170US if your a wimp and can’t build it from the kit).

The driving force of the original tea-carrying doll came from a spring made of whale whiskers (actually whale teeth). All the other components, such as its gears, body and escapement for speed adjustments, were made of wood. How does it work? When a tea cup is placed on the tray, the stopper is released by the whale spring attached to the doll’s arms; the spring forces the stopper to engage again when the cup is lifted from the tray.
