My first dive down the rabbit hole

So I got this to play with around Christmas
 

I ordered a few things, one of them being a bag of servos.. once they came in I decided to play with them and basically figure out whats the deal with servos..

As I looked at the bag-o-motors I realize if ya stick 4 of them together with some tape, voila.. insta robot to test how they work
 

I played around setting them off and evenutally ended using pocketsphinx keyword voice detection on a pi4 to tell it sit, walk, etc..
 

So this got me thinking.. hmm ok.. so how can I build something with this.. build.. ok I got legos.

I decided to challenge myself to build a robot arm with nothing but servomotors and legos. Nothing. Else.
Challenge accepted..

So this was 1/2 the critical solution... figuring out a motor mount.. this ended up fitting almost bizarrely well.

With that figured.. I found if I pinch a block I can use it as an arm.. so then this happened..
 

I kinda reached a stability point with 2 motors, so my "arm" only had 2 degrees of freedom.. still. I call it a challenge success as nothing but legos and motors did this..
 

still nagging in my noggin was the original walking thing.. it never really.."walked".. I want walk. I lifted the lego only thing but only ended up using some tape and a little plastic wrap and superglue for a hub mold.. the other 1/2 of the critical solution..

so putting it all together..
 

turned into
 

and then I found out how very, very, hard it is to make something walk. I even made a model..
 

this was reeeally hard and I never perfected it but I got what I wanted.. maybe feeble.. but walk.. I will probably revisit this..
 

And thus ends my "study" on servo motors.. I think I got it 🙂
