Tick pods? which bots drop?

So I have engineer but havent gotten any pods.
Have been killing all bots from (game doesnt say names so not sure what they are called) the dogs, 2 legged, 4 legged spider type uses gas, and the hugh 2 legged has turret and launcher. Still havent gotten any pods. Yes the hugh and some of the 2 legged use ticks.
Are they more upper part of map or what?

I’m pretty sure it’s only Military and FNIX Hunters and Tanks that drop Tick pods. They can normally be found en masse in the northern parts of the map, yes.

thanks will keep trying then.

Any robot capable of spawning ticks can drop these.
So:
Harvesters
Mili/FNIX tanks
FNIX Hunters
