Help with Linear Actuators

Hey guys, Only new here but thought guys who know robotics would be the best help for my project :slight_smile:

Im into Rc crawlers and i build chassis etc and ship around the world… Im always trying to step things up and push it to the next level… which is why im now here asking for your help! :slight_smile:

I’ll attach some pics in a minute but im needing help with linear actuators like this one…

In the chassis ive designed i would like to replace the centre shock with an LA but having never used them before have no idea how to get them working on a radio (i use the futaba 4pksr)

this is the crawler

this is a look inside the chassis

Folder is you want to see more…

Inside the shock is an internal spring to help suck down the front (chassis pivots up in the centre to get more clearance over big rocks then suck down for lower COG)
There is shock oil to control the speed of its operation as well BUT i would like to have more control of it with a LA but weight is often a factor and i need to keep weight to a minimum.

Thanks in advance for all help

You’re in luck. Choose a 6V -I (PLC /RC) version of the L12 and you can connect it directly to your RC receiver and use it like any other normal servo.
Ex: robotshop.com/en/firgelli-te … =RB-Fir-11
If your main battery is an 11.1V LiPo, choose the 12V-I
robotshop.com/en/firgelli-te … RB-Fir-100
The gear ratio (ex 210:1) means the actuator can provide more force at less speed.
Note that these are not intended to take direct shocks and don’t react anywhere as fast as pneumatic actuators.

Thankyou very much for the reply :slight_smile:

I will order and give it a try… wont know if its a step in the right direction until i try :slight_smile:
