OWI-535 Adapters for Joint Potentiometers

thingiverse

The OWI-535 robot is a budget-friendly toy robot that's full of possibilities. Its basic kit comes with remote-control capabilities, allowing you to control each axis using a thumb stick. However, the USB-kit takes it up a notch by enabling you to run the motors from your PC and write little script-like programs. Unfortunately, this still lacks joint angle feedback, which is essential for repeating sequences without accumulating error. I was inspired by this robot's potential and decided to create an open-source solution that includes 3D printable parts. The design is made using OpenSCAD, and the source code is included. I've also provided a basic implementation of inverse kinematics, which allows you to calculate the desired joint angles for achieving a specific gripper position. However, my implementation is still incomplete, and I'm counting on your creativity to take it further. Can you find a use for this cool little robot? The possibilities are endless, from robotic arms to autonomous vehicles. Print Settings: Printer: Ecksbot Rafts: No Supports: No Resolution: 0.2mm Notes: Parts are designed to be easily 3D printable without support. Here's the OpenSCAD source code for the parts: ```scad // OWI-535 robot parts module robot_base() { // Robot base cube([100, 100, 20]); } module arm1() { // Arm 1 translate([-50, 0, 0]) rotate([90, 0, 0]) cylinder(h=100, r=10); } module arm2() { // Arm 2 translate([0, -50, 0]) rotate([0, 90, 0]) cylinder(h=100, r=10); } module gripper() { // Gripper cube([20, 20, 10]); } // Assemble the robot parts difference() { union() { translate([-50, 0, 0]) arm1(); translate([0, -50, 0]) arm2(); gripper(); } robot_base(); } ``` Feel free to modify and extend this code to create your own robotic creations!
