If I were asked to invent a robot to function in space it would look something like this:

AeRobotic Number One - Watercolor

Light transformer - watercolor

For collecting assorted particles that are flying through space you would use this gathering tree:

The AeRobotic Gathering Tree - Watercolor

And now back to oil painting for a while….
