I've hooked up a spark-core micro-controller to my robot in order to send it commands over wifi (cURL). A robot arm/hand is attached to the robot in order to grab items, lift them, then carry them to the destination.
Love the idea...having major issues with the arm/grabber at the moment. Unsure whether it's a power issue (do I need another servo shield on top of the motor shield to get these servos enough juice...?) or a wiring issue etc. Hoping to have some time for it a bit later this summer. Advice welcome!
