Arduino Chassis for Drawing Robot modified for ULN2003 Stepper Driver Boards
thingiverse
I fine-tuned the chassis by incorporating standoff's to securely mount the driver boards that accompany stepper motors. Those tiny powerhouses have a built-in flashing light display, and my knowledge of robot behavior confirms that robots crave visible indicators, which those blinking lights certainly provide.\nNew Arduino sketch called MyDrawTest.ino allows for a star shape drawing with the assistance of AccelStepper Library\nI recently recorded footage of my bot in action.
