# Forklift Drive Assist with OAK4-D

This example shows how an [OAK4-D](hw-catalog://OAK 4 D) can be mounted on a forklift or other industrial vehicle to monitor the
rear blind zone and detect people during reversing and low-speed maneuvering.

By pairing the camera with the [M8 CAN adapter](https://checkout.luxonis.com/products/m8-can-adapter), the system can plug into
the vehicle network and move beyond a simple standalone camera feed. The result is an edge-AI safety layer that can warn the
driver, notify the vehicle HMI, or feed a braking/interlock workflow when a person is detected behind the vehicle.

### Materials used

 * [OAK4-D](hw-catalog://OAK 4 D)
 * [M8 CAN adapter](https://checkout.luxonis.com/products/m8-can-adapter)
 * Forklift or other industrial vehicle with CAN access

## System Architecture Overview

In this deployment pattern:

 * Perception OAK4-D runs person detection directly on the camera
 * Mounting position The camera is installed to watch the rear hazard zone
 * Vehicle integration An M8 CAN adapter connects the camera workflow to the vehicle bus
 * Driver feedback Detected hazards can trigger an in-cab alert, warning buzzer, or display message
 * Vehicle action The detection event can also be forwarded into braking or interlock logic, depending on the vehicle integration

Running inference onboard keeps the system compact and avoids sending raw video to a separate computer just to make a safety
decision.

> **Integration note**
> The exact response depends on the vehicle safety architecture. Some deployments use OAK4-D only for driver warnings, while others route the event through a higher-level controller that can request slowdown or braking.

## Detection and Response Flow

 1. Monitor the rear blind zone OAK4-D continuously observes the area behind the vehicle during reverse movement or other relevant
    operating states.
 2. Detect a person onboard A person-detection model runs directly on the camera and produces a hazard event without requiring an
    external GPU or industrial PC.
 3. Send a vehicle-side response The event is passed through the CAN-connected workflow to trigger a warning, log the event, or
    escalate to a stop/brake-related action.
 4. Improve operator awareness and safety The operator gets earlier notice of a person in the path of travel, and the vehicle can
    be integrated into a stronger active-safety workflow if required.

## Possible Combinations

The next illustration shows a couple of ideas for possible camera positions and the needed components.
