01 — Overview
Designed and built an autonomous car wash robot as part of a mechatronics group project, integrating mechanical, electrical, and software systems.
02 — Problem Statement
Manual car washing is time-consuming and inconsistent. An automated system can deliver repeatable wash quality with minimal human intervention.
03 — Objectives
- 01Design mechanical carriage and spray system in SolidWorks
- 02Integrate Arduino Mega with motor drivers and sensors
- 03Enable WiFi control via ESP module and MIT App Inventor app
- 04Implement automatic wash cycle sequences
04 — Key Outcomes
Full mechanical design with linear carriage and brush systems
WiFi-enabled mobile app for remote control and cycle selection
Automated wash sequence: pre-rinse, soap, scrub, rinse, dry
Multi-axis actuator coordination via Arduino Mega
