The basic pattern for Japanese hobby robotics at the moment is buying, assembling, customising and programming these gnome sized bipedal robots, though there are many variations, and you are quite free to make superior quadrupedal and hexapodal designs, or whatever original design possible to implement.
They can be customised in a variety of ways, in a cross between upgrading a PC (in this case adding better servos, sensors and so forth) and decking out a ride (with custom bodywork, etc.).
It is of course possible to buy pre-assembled units for a premium.
Many of the models are not really robots (as in possessing autonomously operating capabilities) per se, being mere remote control marionettes, but some do have sensors – the focus is still more on pre-programmed dancing robots than ones capable of usefully responding to their environment.
Separate shells for many of the more popular models can be bought, which mostly entails emulating the look of certain giant robot suits which seem so popular with the Japanese.
Masamune Shirow and Armored Core fans, rejoice! This little quad model is quite impressive – functional insectoid designs trump excessive anthropomorphism where practical robots are concerned.
It should be apparent by this point that this is an expensive hobby. Anything less than ¥100,000 is probably just a shell or set of servos.
The shop also has consumer toy robots like Pleo, and other smaller bots.
This is one of the most unassuming and uncharismatic (apart from the Hello Kitty robot) items in the shop, but in certain respects represents a technology at the very van of the robotics revolution, and with profound economic repercussions.
As can be seen, it is a straightforward (and probably rather low-end) robotic carving device, able to take data from CAD software and render it in whatever physical medium the machine can work with.
