Competition Gripper

thingiverse

A glimpse into the future is already visible - prototype pictures and videos have been released, with complete 3D printed images to follow soon. https://youtu.be/01WmIjBVEu0 This innovative gripper can effortlessly pick up foosballs stuck in corners or against walls. In the unlikely event of a servo malfunction on competition day, it only takes a few minutes to replace it. The cost is remarkably low, making it an attractive option for many. The original grippers were crafted from wood and built using a scroll saw, but have since been transformed into 3D printable objects. Additional components include: * Two SG90 Servos (priced at just a few dollars each) * Two coat hangers * A handful of small zip ties from the dollar store The files are still undergoing refinement. The source code for the gripper and open scad files can be accessed 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 For usage information, refer to SRC1_sonic_striker.py. However, if you are using a pwm servo hat to drive the servos, Grabber.py is the code of choice. This gripper has already made its debut at the Virginia Beach STEM Robotics competition in 2017.
