Moving tree sculpture - how to sketch it?

Hi guys, great to read all the terrific knowledge here. I need a sketch. Offering to Paypal if that is ok with the forum.

Interactive tree sculpture, 13 feet tall. You guys are familiar with “continuum robots”… Mine has 3 segments, each with X and Y movement = 6 channels. There’s a construction photo below.

The goal is to loop short, random movement functions so it has an unpredictable life of its own. Slowly, like a tree branch swaying. It would run all day on exhibition for weeks at a time.

Hardware:

  • 6 Creative Werks 110lb. actuators with potentiometer feedback.
  • 3 L298 H-bridges that are melting and I need to upgrade.
  • Mega 2560.
  • Grove base shield and 3 joysticks for testing movement.

The sketch I need would include:

  1. A reset function to center all actuators.
  2. Proportional easing so movements are not sudden.
  3. Run all 6 channels simultaneously.
  4. A fail-safe to call the reset function if (paramexceeded).

For example, a single channel would move back and forth at (rand) speed, for ((rand)duration || (rand)distance - whatever you think is best).

Hi, Welcome to the forum.

You might do better to ask the moderator to move your post to "Gigs and Collaborations" part of the forum.

Tom... :) PS, Use the "report to moderator" facility at the bottom of your post.

The photo attached to your post does not remind me of a tree, and the description of what might be moving and how doesn't make any sense at all.

Gotcha Tom, thanks, will do.
