Robot Grabs & Throws ERP test

This was a very simple test to verify that my ERP was capable of grabbing and throwing a tennis ball. In no way did I optimize the throw, so I'm sure it can throw further after a bit of tweaking.

No sensors were used in this test, although in the long term the camera will track the orange ball before grabbing it.

like make it a smooth motion that continues throw the throw as the arm begins to swing forwards, have forearm move either slowly up (if not try down)

this should give some extra umff(as long as u have heavily geared servos to prevent breaking)

As I mentioned in the info box, it was just a crude hack throw. I in know way put effort into optimizing it - and in fact it just worked my first try so it was good enough. This was just a test to show it was possible, where in the long term I plan to use AI to optimize the throw.

Fantastic robot, I never got my $50 Micro controller working :( , I was wondering if you had like a Axon Lite that costs like 20-40 dollars with less features instead of the $120 axon?

The Axon is now $100.

u should make a sensor so it would chase the ball and then give it back

[palmisano]

Well the plan is to use the camera to track the ball.

[jedi1ryan]

great! i'll be waiting in line day 1

[jellis359]

to add more distance to the throw i would put a final motion of the forearm flicking or moving upward at the point of seperation of ball and end effector

[palmisano]

Its not actually tracking anything yet. Having issues with the camera lately . . .

[palmisano]

Thats my long term plan!

yes
