Constructed from durable 3D-printed parts and acrylic sheets, this robotic car features four large wheels driven by DC motors for easy navigation across various terrains. At its core, the **OAK-D AI camera** is mounted on the car's top lid to monitor distances between personnel and machinery, enhancing safety in environments like construction sites by measuring distances between workers and heavy equipment such as excavators. The **KRIA** platform handles real-time model inference and visual display, while **servo motors** enable precise camera movement for comprehensive coverage. Remote control is achieved through a connection system using **Streamlit + Ngrok or Luxonics Hub**, allowing operation via a web app from anywhere globally. This connectivity ensures versatile deployment across industries, offering real-time surveillance and safety monitoring to enhance operational efficiency.--DIVIDER--## Problem Statement Traditionally companies hire multiple safety officers for each construction site to ensure workers safety Managing worker safety on construction sites. This approach have following issues: 1. Transportation costs of Safety Engineers. 2. Ensuring timely payment of monthly salaries of safety officers/ Engineers. Additionally, there are persistent problems related to corruption and negligence. These challenges necessitate a robust and efficient monitoring system to ensure the safety and well-being of workers. --DIVIDER--## Proposed Solutions ![Solutions](https://hackster.imgix.net/uploads/attachments/1726003/image_6hVhDjDJeo.png?auto=compress%2Cformat&w=740&h=555&fit=max) To address the challenges, we propose a multi-faceted approach. Stationary cameras are installed around the site to provide continuous surveillance and monitor worker activities. Safety helmet cameras are utilized to offer a first-person perspective, ensuring real-time monitoring of individual workers' safety and compliance with safety protocols. Additionally, robots equipped with advanced computer vision technology are deployed to autonomously navigate the site, detect potential hazards, and provide dynamic surveillance, enhancing overall site safety and efficiency. We have used Robot because it can be controlled. Moreover AI portion can be installed on **IP cameras/normal cameras** as well but this documentation will focus on the deployment of the AI on the Robot using Kria. --DIVIDER--## Objectives - Enhance Workplace Safety - No need of Safety Engineers. - Advanced Surveillance - Improve Operational Efficiency - Global Remote Control - Versatile Deployment --DIVIDER--## Why Neuro Optix?

This will provide a holistic view of the construction site, enhancing worker safety through comprehensive surveillance. #### Quality Assurance Drones will also be utilized for quality inspections from above, ensuring construction standards are met and maintained. This aerial perspective will help in identifying and rectifying issues that might not be visible from the ground. #### Worker Training The robot will be capable of providing training and informing workers about safety protocols by analysing the worksite. For instance, if an activity involves working at height, the robot will instruct workers to use fall protection restraints. This functionality is powered by a GenAI model, deployed on the cloud. #### Worker's Safety Conscious The robot will utilize its sensors to monitor environmental conditions (e.g temperature, wind speed). In adherence to ILO guidelines, it will notify workers to take breaks during peak sunlight hours to prevent heat-related illnesses such as heat exhaustion or heat stroke. #### Autonomous Petrol Robot will autonomously perform certain tasks such as guiding the crane operator and patrolling the site using 3D LiDAR. ## Note: The Working on the Robot is still going on to convert it in to product and we are properly consulting the Health and Safety Coordinator Mr. Zaka so that we could achieve the best we can. # Thanks For Reading.
