Competition Gripper

thingiverse

The picture and video show prototype. Will put completely 3D printed pictures up soon. https://youtu.be/01WmIjBVEu0 This gripper can pickup foosballs that are in corners or against a wall. If a servo is damaged (on competition day) it should only take a few minutes to swap it out. Relatively inexpensive to make. The original grippers were build with wood and used a scroll saw. They have been converted to 3D printable objects. Extras: * Two SG90 Servos (should only be a few dollars each) * Two coat hangers * Handful of small zip ties (from dollar store) Files are still being tweaked. Source code for gripper and open scad files can be found at Open Scad files https://github.com/EricRohlfs/UltrasonicStriker/tree/master/3D-printer-files/foosBallGripper Python Code : https://github.com/EricRohlfs/UltrasonicStriker/tree/master/code See SRC1_sonic_striker.py for usage, but Grabber.py is the code you may want to use if you are using a pwm servo hat to drive the servos. First used in the Virginia Beach STEM Robotics competition 2017.
