[SOLD] For the cost of shipping only: OWI-535 Robotic Arm Edge (assembled) + Prop control. + extras
Hopefully I'm not violating any of the forum rules regarding selling items. This is a propeller-based project that I'm selling for less that the cost of shipping.
That said, I'm cleaning up some of my unfinished projects.
This one was a robotic arm that I never figured out a good purpose. I've modified it with position sensors (pots with ADC and hall-effect sensors). The modifications were made so that the arm can still operate by itself (you simply move the controller connector to the proper connector).
Included is a propeller-based controller board, display, motor driver boards, voltage converters, etc. Includes all chips needed for operation, including the Prop. You'll need a couple of 6-9 volt power supplies, recommended at least 2 amp for the motor power supply. Also recommended are 4 D batteries, not for power, but for ballast.
Also included are spare parts, 2 continuous-rotation servos (not Parallax), 2 stepper motors, and various other hardware items. Finally, the book "Junkbots, Bugbots, & Bots on Wheels" will be in the package.
The robotic arm kit, by itself, goes for at least $35.
I'll pack all of this up and send it out for $20. Estimated shipping is more than that, but I'll absorb the difference to get this into the hands of someone who can use it.
PM me if you're interested or have questions.
