Bluetooth-Controlled
Robotic Arm for Street Waste Collection
🔧 Project Description
This project
is a mobile robotic arm system designed to collect waste from the
streets and deposit it into a rear container. The robotic arm is mounted on an RC
car chassis and controlled remotely via Bluetooth using a mobile phone.
🚗 System Components
1.
Robotic Arm:
o The robotic arm
is equipped with multiple servo motors.
o The base
rotation, arm joints, and the end-effector (gripper) are all
operated using servo motors.
o The end-effector
(gripper) is used to grab and lift trash items.
2.
Mobile Platform (RC Car):
o The robotic arm
is mounted on a chassis with wheels.
o Movement is
powered by DC motors, controlled via a motor driver module (e.g.,
L298N).
o The robot moves
forward, backward, and turns left/right using the motor driver.
3.
Control System:
o The system is
controlled remotely using a Bluetooth module (e.g., HC-05).
o A mobile
phone sends commands to the robot via a Bluetooth terminal or custom app.
o An Arduino
microcontroller receives the commands and controls the servo motors and DC
motors accordingly.
4.
Trash Storage:
o A storage box
or container is mounted at the rear side of the chassis.
o The robot collects
trash using the gripper and places it in the container.
🧠 Purpose and Functionality
- The robot is designed to help in
street cleaning and trash collection.
- It can be used in narrow
alleys, small parks, or remote areas where human access
is difficult.
- The system allows remote and
safe collection of harmful or scattered waste.
