Linear Positioning System

This document outlines the critical components of a high-precision linear positioning system designed by Tony Swanson and Chris Biedrzycki. Key elements include a lead screw paired with a lead nut featuring a reflecting plate for accurate positioning. The system utilizes an ultrasonic sensor capable of measuring distances from 4 to 30 inches and ensures repeatability within 1/16 inch. A robust 24V DC gear motor, offering a maximum speed of 115 RPM and a stall torque of 214 in-lb, drives the system, supported by durable ball bearings and vertical supports.
