The robo arm looks really tough and durable. Thanks for letting me have a look at your work!

I bet once youve done this enough you can quickly rig up lots of different equipment in all sorts of haphazzard wayz. amazing.
Is that PLA plastic? it looks organic.

Did some more work on it, your seeing me go thru about 6 or so random settings in this video.

3d printer can help alot, they are cheap and well made and work wonders, make sure you get one and get yourself a download of open s-cad to go with it..

Im not that knowledgeable really, but I think if I dont answer this post no-one else will.
All the controls of the lawn-mower need actuators on each one.Then you need sensors, like a couple of eyes and a couple of ears.
You can send the sensors to the computer, and the computer sends back to the actuators, and then u can run all the a.i. in software. which makes things easier.
Using high frequency gigahertz radio signals is the best, but u can use ultra-sound or ordinary 60hz-20khz sound, then u only need an ordinary speaker and microphone from your computer, to signal to the drone. Thats what im going to be doing for mine. but im a little strange and I dont use integrated circuits, I prefer more home made from scratch.
I wonder what that would sound like, there would be rectified sine waves in the air.
Sorry if u dont like my post, its the best I can do. I admit I am a little strange, and I do things in different ways that may be annoying...

Isnt it a bit full on making robots, especially self driving cars where its not even legal really... its not really for everyone. its a bit hardcore for enthusiasts only I think.
How big are these "vehicles" going to be? If it was just little Go-fors I guess it might be ok, but big hunks of cast and folded metal is a bit dangerous.
Then theres all the motor drivers and circuitry, then the computer and then all the a.i. software.
It would be cool if you could give us a rundown of your a.i. controlling system tho! =)

Cheap resin printers pack ALOT of punch these days!

Looks like I own this section =)
Heres an old video of my first delving into random motor searches inside physics engines, and he walks along ok, besides the fact its skeleton isnt constrained properly, its getting one of its hip dimensions out of the dodgy rig, and it isnt hitting the ground properly. (It gumbies along at times.) The amount of motor searching is very small, its only 3 frames in front all directions, but even that small a time section can still get the robot to continually correct itself from where it is.

Also! the cool thing (when i finally get it finished) is the new brain is using a more proper induction system that means I dont actually give it the physics code for it to sample from, it has to learn it before it can use it, and thats the main difference between a real robot and one thats stuck in the computer and cant get out. Two of the great practical benefits is the physics it learns is synched to its environment, and it possibly works without encoders if it at least has some clue to work out its body positions from.

(EDIT: sorry I had my adblocker on and didnt see the help you already got, its off now, its only my first day at the site.)
The longer the arm is the bigger the motor has to be, but I havent actually got much experience, im pretty sure if you did the mathematics its not a difficult problem to get right first time on paper.
What I can actually help with tho, is that it doesnt matter even if you just use ordinary motors without step control, as long as youve got a h-bridge to go back and forth, you can add the encoder yourself, James Bruton (xrobots) on youtube makes his own from scratch encoders... you just need to switch from full left to full right, and thats all you need, when the arm hits the target itll oscillate to stay still.
Also, you can use the maxwell effect, and use capacitors as the actuator, and then these actually dont need feedback to hit definite positions.

This isnt inverse kinematics, but its a virtual simulation of the robot springing back off the ground so it can walk in the computer, given a motor search.
I can explain more if you want me to, but heres the video of it ->
