New Bioloid STEM (CM-530 & AX-12W)

[siempre.aprendiendo]

It seems that Robotis is launching in Korea a new kit/box called Bioloid STEM (S Science, T Technology, E Engineering, M Mathematics) (support page)

(All the links are to Korean pages, but viewing the photos and automatic translations are enough to understand it )



It includes new parts and new "versions" to some of our old friends:

A new AX-12W:

A new CM-530 (STM32F103RE 32bits ARM)



And new IR array sensor

Such a speed, it seems that AX-12W is better for wheel mode than join mode, compared to AX-12A. But AX-12A is better for join mode, because AX-12W speed for join mode is slower. Correct me if I'm wrong.(just thinking how robotis could manage to differentiate the speed between wheel mode and join mode in one package?)

AX-12W>>>No load speed : 482rpm (at 12V, Wheel Mode), 54rpm (at 12V, Joint Mode)

AX-12A>>>No load speed : 59rpm (at 12V)


As for the CM530, I'm wondering about how fast it's clock frequency?any info about that?anyone have info about whether it will be available for international market?when?

Cool kit, I hope it is sold in the US!

There is some more programming information about the CM-530 here:

and here:

Seems a shame they did not incorporate gyro and accelerometer, it would have added less than $5 to the component cost, and made a much more valuable controller.

Compared with the AX-18A and the 12A, what so special about the new motor? Is the encoder an optical one? According to the support site, the torque of the new AX-12W is 0.2Nm (2kgfcm). It seems to be way too small compared with the others. Is there a typo?

The AX-12W appears to be just the same as the AX-12, but with different gearing. Thus in wheel mode it can achieve 470 rpm, 8 times faster than AX-12, but 8 times less torque.
