Projects That Speak

Motive

The enCOMPANION is a small-scale cleaning vehicle which can be customised as either bluetooth connected, IR remote controlled or line following where the cleaning part is solar-powered. The main purpose is to clean continuously with full efficiency and thus can overcome human fatigue. I have created this in order to reduce the workload on sanitation workers giving them a better working environment while also promoting sustainability and cleanliness.

The enCompanion is also beneficial as it can be used during harsh climatic conditions given its ease of operation. Moreover, operating this does not require high skills. So, it can serve as a way of generating new means of livelihood to disadvantaged workers at the same time ensuring their safety. Furthermore, It can primarily be used to clean roads(for snow and dust) in dangerous terrains, reducing loss of human life.

Technical Details

I created the structure of the car by assembling the 3D printed parts of the chassis, DC gear motors and wheels. The back end is fitted with a cleaning motor that has rounded scrubbers attached to the axle of a large DC motor. The motors are driven using L298N motor driver

The three variations make use of  Bluetooth module HC05 , IR sensor and IR receiver respectively.

In the first variation communications are made through the HC05 module which is connected to the RX and TX pins of Arduino Uno. In the second, the IR sensors use infrared signals to differentiate between the black and white colour of the ground and thus, lead to line following movement. This variation also includes a 9V solar panel attached to the cleaning motor.

In the third variation, the car is controlled using an IR remote that sends signals to the IR receiver whose base, transmitter and emitter pins are connected to the Arduino board. I used the Arduino IDE written in C++ to program the enCompanion. In the process of analysing the optimum power to run the robot, the arduino uno got damaged. I had to replace the voltage converter integrated chip of the arduino board. So some soldering had to be done. The batteries used for powering are rechargeable Lithium ion batteries each of 3.4 V and 3000mAh.
