Key Features:

• Automated Food Service: The bot precisely follows a black line on the floor, stopping at designated positions to serve food to residents, ensuring timely and convenient meal distribution.
• Dynamic Obstacle Detection & Safety: Equipped with ultrasonic sensors, the Serve-bot can detect and stop for obstacles in its path, including people or objects, prioritizing safety and preventing collisions. It automatically resumes its route once the path is clear.
• Resident Needs Recording: A unique feature of the Serve-bot is its ability to record specific needs or requests from residents using an integrated voice playback module.
• Centralized Need Playback: At the culmination of its service rounds, all recorded resident needs are played back, allowing caregivers to efficiently address individual requirements and provide personalized attention.
