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 poor sheep!..
That's looking really good!
Its looking really good! Good work. What servos are you using ? They seem unusually loud for a light load. Are they analog or digital position controlled? Again good work - Josh S
Very friendly all boys, smoothness arm is thanks to ServoSpeed , now I have to play around with "relative servo" to ensure a horizontal position of the claw to manipulate a glass of water without spilling. List servos (all analog): -elbow: Turnigy s8166m -wirst: TowerPro MG995 -claw: Hextronix HXT900 (2 units)
Yep I too love round robots, nice job on the arm. My favorite round robot was Jinx from space camp.
Precisely served me inspiration that robot, I saw the movie and thought the original design and although at first I thought of doing the robot with the legs and head with an extensible system, but besides that the price soared very high, I left no room for the boom, so I decided to do something more functional and less costly, greetings.
Excellent choice
Hi guys, Just an idea. I sometimes get lazy so I use something already available. How about using a Six for the legs instead of wheels? Looking at the picture of Jinx gave me the idea. Just a lazy man idea.... Thanks for sharing the build. Cool arm and I'm looking forward to the next steps
