This the result of too much free time lately, the new project is a robot drawing a sphere, using the low-cost approach to the selection servos and other components, with a retractable arm that comes from inside through a gate and once inside collected no space and is also protected when not in use.
This is an area of 28 cm in diameter (11 inches) of PVC, is a large Christmas ball, once cut in half I've noticed that need structural refurzos to hold its shape once installed all the electronics and mechanics. So I will use sections of an empty roll of wire for reinforcement.

That's sweet, I love it!
Pretty cool idea. Kinda makes me think of the robot Marvin from Hitch Hikers Guide to the Galaxy movie.
Glad to hear that RS is welcome here (now you are your friends). I'm building a temporary aluminum arm, weighs 120 grams (4.23oz) a little less than the hand with servos, although, the final model will weigh about 170 grams (5.99oz) and will be stronger. In total arm weight you have to move the servo s8166m is 320 grams (11.28oz) fairly light considering its length. According to calculations can handle objects of 250 grams (8.8185oz)
This is the space occupied by the folding arm inside the sphere, will open a rectangular opening in the bottom half of the field to take his arm. The linear drive system to pull the arm off a headache interesting, although, I'm on it, and enjoy.
love this build.
Do you have anything against me using your sphere as an example for my latest creation?
Rc car base, sphere body.
Technopro Sorry but I do not understand your question: "Do you have anything against me using your sphere" ?
sorry, i was half asleep.
i meant to say "do you have anything against me using your idea, but doing some modifications?"
my idea:
this is a blueprint for A.R.I.S., or Artificial Robot Intelligence System. Will post project soon.
Again your idea is awsome.
