This advanced automated toolbox integrates two custom-designed PCBs, each specialized for distinct functionalities: one dedicated to precise motor control and the other focused on intuitive HMI integration. At its core, the system employs an Arduino Nano, seamlessly orchestrating movements through SG90 servo motors, high-precision stepper motors, and a linear guide to ensure smooth and accurate mechanical operation. User interaction is elegantly facilitated via a 2.4-inch Nextion display, providing a responsive and user-friendly interface. The entire setup is housed within a sophisticated, robust mechanism engineered for reliability, precision, and ease of use in demanding environments.
This project analyzes the angular displacement at a joint for a rotating bar, later expanded will be expanded into a four-bar crank-rocker mechanism. It will later include FEA Analysis for stress and fatigue analysis on the aluminum 1060 alloy linkage, predicting potential fracture points under high loads and repeated motor use.
Goal: To mount a linear actuator onto each compartment to push out/in while keeping Design Specs.
Problem: The design for the linear actuator is to large sizing up to 76 mm (3 inches) where we need our spec to meet half the size (1.5 inches)
Solution: Need to create a linear actuator system that meets within 1.5 inches to meet criteria looking for a cosine performance chart to meet design requirements based on displacement, time, and speed applied (10 rpm).
This circuit interfaces an Arduino Nano with a Nextion Discovery HMI display to control four servo motors for actuating a four-bar mechanism, which lifts a top cover for tool access. It includes a USB-C Li-Po charging input, a buck converter (XL6009) for voltage regulation, and an I2C bus expander to manage multiple PWM outputs for the servos.
