Set all servos to 1.5mS - takes multiple tries

Hi all,
First post here - total n00b. Already broke some servos, etc.

Ok - I have my arm assembled w/ SSC-32 (no ABB-BA28 on this one).
Using RIOS to play around.
Started RIOS
Powered up SSC32
Clicked “All=1.5mS” >>> random, small jerking motions
Clicked “All=1.5mS” >>> random, small jerking motions again
Clicked “All=1.5mS” >>> finally moves to shoulder vertical, elbow 30deg etc.

Doesn’t seem to matter if robot is in default position or close to 1.5 position.

Am I doing something dreadfully wrong?

I have to turn this over to a troop of girl scouts to drive via joystick in 2 weeks and I dont have time to burn boards etc.

Thanks in advance for any and all info!

How do you have this all powered?

You will need at least a good 6V battery pack or wallwart for the servos. I’d also recommend using a separate 9V battery for the logic (electronics).

How do you have the SSC-32 jumpered for power? It would help if you could post a nice closeup picture of your SSC-32 showing the jumper setup.

Hi Darrin,

Take a close look at step 15 and 16 in the base manual.

It describes how to power the electronics separately from the servo motors. This will fix your problem. :smiley: Send me some Thin Mints if it fixes the problem. lol :smiley:

I am sure that the power is the problem, now that you guys bring my attention to it. I indeed have VL=VS jumpered, all to the wall source.
I was wondering what all the “extra” 9v adapters were for! :slight_smile:

Thin Mints? Carmel Delights Rule! I can eat a whole box in one sitting! :stuck_out_tongue:
