  2. Question(s) Re: Dynamixel MX-28T: installed Maxon RE-max motor?

    Th MX-28T uses a standard 12V motor from Maxxon. The Robotis motor has a custom Maxxon part number due to the custom 13 tooth 0.3 mod gear laser welded on its shaft....

    Re: MX-64T half-dead H bridge?

    The AUK SUF2001 MOSFET's used have a built in reverse body diode http://www.auk.co.kr/pro_upload/SUF2001.pdf
    It's certainly possible that if there is insufficient filtering on the motor or a motor...

    Re: MX-64T half-dead H bridge?

    I think the older rx-28's and dx-117's have a proper pwm ic with a built in thermister. The newer mx-28's and 64's have only an h-bridge which is very similar to the ax-12 design.

    News/Announcement Re: Dynamixel MX-64 and MX-106

    Looks like the gear ratio is different too.
    EX-106+ is 184:1
    MX-106 is 225:1
    So perhaps the motor is the same.

    News/Announcement Re: Dynamixel MX-64 and MX-106

    I've worked with EX-106/106+ for sometime. I don't believe ROBOTIS states accuracy on their website. Control angle does not equal accuracy. The EX uses a low resolution encoder on the motor...

    News/Announcement Re: Dynamixel MX-64 and MX-106

  9. Re: Cheap Thermal Camera?/Best Way to Detect Location of Human/Animal?

    Cheap cameras with no IR cutoff and IR filter will detect 700-900nm light, the peak emission of the human body is at 9500nm or 9.5um and the range of human body emission is 7um to 14um so in reality...

    Yes, I have opened many Ex-106's, there is a potentiometer on the output shaft and a low resolution encoder on the motor.

    No, you cannot yet purchase the MX-28, as they are now called. Hopefully...
