Quadruped Robot with Both Manual and Autonomous Control Modes https://www.hvstechnologies.in/product/hvs-902-quadruped-robot-with-both-manual-and-autonomous-control-modes/ https://www.hvstechnologies.in/product/hvs-902-quadruped-robot-with-both-manual-and-autonomous-control-modes/#respond Wed, 19 Aug 2026 07:01:11 +0000 https://www.hvstechnologies.in/?post_type=product&p=29330 This project focuses on the design and development of a quadruped robot with both manual and autonomous control capabilities. The robot features four legs, each with three MG90 servo motors, totaling 12 servos, which are controlled using a PCA9685 PWM driver connected to an ESP32 module. The ESP32-CAM is integrated to provide live video streaming, enabling real-time monitoring. For obstacle detection and avoidance, an HC-SR04 ultrasonic sensor is used in autonomous mode to navigate safely.

A web-based interface is developed, allowing users to control the robot remotely and select between Manual Mode (direct control via the web interface) and Autonomous Mode (self-navigation using sensor feedback). The ESP32 acts as the main processing unit, managing servo movements, sensor data, and web communication.

This quadruped robot combines embedded systems, wireless control, and real-time video streaming, making it useful for applications in surveillance, robotics research, and autonomous navigation experiments.

 

 

 

 

 

Objectives:

  1. Design and develop a quadruped robot with four legs, each controlled by three servo motors.
  2. Integrate an ESP32-CAM module for real-time video streaming.
  3. Implement an HC-SR04 ultrasonic sensor for obstacle detection and avoidance in autonomous mode.
  4. Develop a web-based interface to control the robot remotely.
  5. Enable mode selection (Manual/Autonomous) via the web browser for flexible operation.
  6. Ensure smooth and stable movement of the robot for effective navigation.
