Control of a SES arm via RIOS

Hi folks,

As part of my University project, I’ve got to implement a controller for the department’s SES robotic arm using an FPGA. As part of the problem analysis, I’ve been looking at RIOS’s functionality.

I appreciate that the source code is not available, but does anybody know how RIOS controls the arm? The user manual for the SSC-32 talks about the use of commands such as:

# P

etc to set the position for each channel. I’ve got a COM port monitor running, and this is indeed how the functionality for “All=1.5mS” is done. But when I open the SSC-32 Configuration dialog (with the 8 vertical sliders) and start moving the arm via those sliders, all that ever gets sent is:

#VA B C D.

Which, according to the SSC-32 documentation is a query, not a position command!

Is anybody able to shed any light on this for me please?

Thanks very much,

Nick

  • SES Robotic Arm
  • SSC-32 with Atmega168
  • RIOS v1.05
