Hello,
Is there a erector starter kit or precompiled parts list to build a Lynx 6 arm equivalent?
Can the erector type arms be controled by the RIOS software too?
On a separate topic, does anyone know of any sample VI files for controlling a Lynx arm using Labview software
w w w. ni. com /labview/ whatis/
I am looking to assemble an arm as fast as possible, the control program will be written later.
Thanks in advance for any guidance.
Everyone here seems very knowlegable.
The best thing to do is go to the “what can I build” page and look at the assembly guide for the SES arm. There is a list of the brackets used at the top of the guide. This arm is 6" between each axis point. For comparison the L5 is 3.75" and the L6 is 4.75" between each axis point. The SES arm can be controlled from RIOS as well. There are many posts here concerning LabView. I recommend you do some searching for LabView on the forums to find more info. I do know the SSC-32 does work with it.
Thanks Jim
The SES guide was very helpful.
I am trying to decide between the Lynx6 and a SES version.
The SES version is a bit larger and closer to the reach I need. However the Lynx6 is better suited for the task. The less metal the better because the arm must perform tasks reaching into a test chamber where radio frequency testing will be performed. The metal could affect the fields.
I have gathered the list of parts needed for the SES, it seems to be about 20% more cost wise, but more versatile. Maybe I will buy both the Lynx6 and a SES reusing the controller from the Lynx6 and try both out. Does anyone know by looking at this list if it would be totally complete for the SES? The base appears to come without a servo and I didn’t know which one to buy for it so increased the order from 4 to 5 with the HS-645MG.

I wounder if the tubing and hubs could be replicated using thin/light PVC tubing of some kind.
You might consider adding the LPA-01 low-profile axis, which gives wrist rotation. That will require another servo. Also order a set of springs (SPR-01).
And you’re going to need cables: three 12" servo cables, one 6" cable, and one “Y” adapter cable (to drive the twin shoulder servos). And get a pack of 100 wire ties to secure all those cables.
I ordered seven HS-645MGs for my SES arm, but I wonder if I could have gotten by with lower power servos for the gripper open/close, and maybe the wrist rotate. Is there any benefit to using HS-645s for those functions?
I also wonder whether the dual-servo shoulder might be replaced with a single higher power digital servo, like the 5990. This might cost a little more, but would there be any gain in performance or smoothness?
Finally, if you’re concerned about metal content, then consider using the new plastic turntable instead of the metal arm base.
Be careful of the RF generated by the servos. They may need to be sheilded.
