Linear Actuator Control with SSC-32

Hey guys, have a question.

I’ve been designing a hexapod (3 sections per leg plus foot) which will be powered by 18 linear actuators (these: firgelli.com/Uploads/L16_datasheet.pdf ) and 6 servos for leg rotation. I was planning on controlling them using an SSC-32 with an H-Bridge circuit for each LA motor but am having trouble figuring out the rest of the wiring required. From the LA spec sheet, pin 3 and 4 should correspond with the VS and Ground pins through the H-Bridge. Then it seems like pin 2 would link with the Pulse pin for position control while pins 1 and 5 would require the two reference voltages stated that I haven’t figure out yet.

My question is in parts as follows:

  1. Am I correct in my assessment of the pin connections of the LA to the board and if so:

  2. What would be the appropriate reference voltages for the position signal?

  3. If all of this is not going to work as I’ve imagined, is there anyway to make a go-between from the board to LA work and if so how would I go about doing it?

Any help would be greatly appreciated!

Probably not what you were thinking, but you could probably turn the 12v linear actuator into somewhat of a servo by using the below servo internals (driven by an ssc-32) to drive the below h-bridge, which drives the linear actuator.

The L16 is not directly R/C controlled. You need one LAC controller unit for each L16 actuator:

Interesting design!
