You can use this robot for cleaning water

DTMF is a Dual Tone Multiple Frequency decoder module which has a MT8870 DTMF decoder IC which decodes DTMF tone signal to digital signal that are acceptable for arduino digitally. Here an aux wire is needed for connecting DTMF module to phone.

Voice control robot that controlled bluetooth hc-05 via a smartphone app. The app is developed in such a way that it convert the voice command to text and transfer the text to the connected Bluetooth device.

Spider Robot has four legs and make its movements using these legs, the movement of each leg is related to the other legs.

In this project, we made a Robotic Car which is controlled by Bluetooth Module via Phone. This project is made by Shivam kushwah, Hardik bandil from IOT 1st year.

In this Project, how to build a simple robot using Arduino that could move towards the fire and pump out water around it to put down the fire.

Path follower robot senses black line by using sensor and then sends the signal to arduino. Then arduino drives the motor according to sensors' output.

This project developed by Niitin singh chauhan, Devendra singh and Ravi yadav. This Robot is an intelligent device which follows the line (black path).if there is any obstacle on the line so this robot automatically sense the obstacle in front of it. And avoid them by turning itself in another direction and automatically come to their original path.

This Robot can be controlled wirelessly using any Wi-Fi enabled Smart Phone.

This project developed by Nitin singh Chauhan, Devendra Singh, Neelu Devi and Khusi Gupta IOT 1st year. In this project you will see how to make a Obstacle Avoiding robot.
