    Question(s) PincherX gripper specs

    I can't find the specs for PincherX gripper. What is the maximum opening and approximate holding force at about 2" open? How long are the fingers?
  2. Question(s) What are the PID parameters in continuous rotation (wheel) mode for MX-12W?

    MX-12W has a quadrature encoder for speed control in continuous rotation (wheel) mode. Are they using PID parameters from registers 26 through 28? If so, it seems that PID parameters are shared...
  3. Mounting a timing belt pulley on Dynamixel AX12-A

    I would like to mount a small size timing belt pulley on Dynamixel AX12-A. Can I buy such a part somewhere?

    Re: MX-12W?

    It looks like a direct replacement of AX-12W with magnetic encoder instead of potentiometer and ARM Cortex M3 instead of Atmel AVR microcontroller. It seems that a major functional difference is...

    Question(s) Re: HerkuleX Servo's?

    Hi Joe,

    I'm curious why you selected HerculeX over Dynamixel? Was it the price? Granted, single piece costs less ($36 vs. $45), but 6-pack costs practically the same. Technical reasons?

    Re: Uptech Robotics clone of Dynamixel

    Technically, they can be arbitrarily close, when acceleration is reduced to near zero.

    Re: Uptech Robotics clone of Dynamixel

    This data suggests less than manufacturer specified performance, assuming adequate power supply. Stall current for this servo is about 1.3A (from the datasheet). Voltage measurement during stall is...

    News/Announcement Dynamixel MX-64 and MX-106

    I just concluded a nice email exchange with Robotis and they informed me about release of Dynamixel MX-64 and MX-106, which they hope will happen in December this year. Both servos will have TTL...

    Uptech Robotics clone of Dynamixel

    I just stumbled upon a clone of Dynamixel (same bus and protocol with some extensions) in standard servo form factor: http://www.robotshop.com/uptech-cds-5516-serial-robot-servo-3.html. Needless to...

    Question(s) Re: HerkuleX Servo's?

    For a while they were listed at RoboShop, but mysteriously disappeared. There is a place in Australia selling them: http://www.tribotix.com/Products/Dongbu/Herkulex/Herkulex.htm.
  11. Question(s) Re: Reading Dynamixel's position in Wheel Mode

    Thank you for clearing this up. BTW, the thread you linked to contains this from Robotis guy: "... the new MX-28 (and other MX series) ...". Do you have any information about other MX series?
  12. Question(s) Reading Dynamixel's position in Wheel Mode

    Hello,

    After some googling I still don't have a clear answer. It seems that higher end models (MX-28 and EX-106+) will return a valid position value (overflowing) in wheel mode. All other models...
