Robotics has come up in a huge way. It’s not just something to meddle with now. A dedicated stream of engineering has come up in several engineering colleges. College events, Robotic festivals and competitions see a very large interest from robot enthusiasts. We compiled this list of 20 robotics project ideas. How many have you tried?

Make Your Own Remote Controlled Robot
To control a robot, the signal is usually sent through a wireless system using radio frequency (RF) and infrared (IR). To send an IR signal, you need a transmitter and a receiver with an encoding and decoding system. Presented here is a simple remote-controlled robot that can be controlled using an IR remote that is used for a TV or DVD player, or an equivalent IR remote.

Colour Sensing Robot with MATLAB
Presented here is a MATLAB-based project where images taken by the camera are processed for colours and the position of a red-coloured object is extracted out of the image. Based on the position of the red coloured object in the image, different data are sent via COM port. The serial data are received by the robot and the corresponding movement is done. You can change the code for any colour that you find suitable. This project is just an example and you can use this for various industrial applications such as controlling heavy load-lifting machines with some object of a specific colour in your hand.

Wireless Gesture-Controlled Robot
In this project, we are going to control a robot wirelessly using hand gestures. This is an easy, user-friendly way to interact with robotic systems and robots. An accelerometer detects the tilting position. A microcontroller gets different analogue values and generates command signals to control the robot. Robotic arms used for welding or handling hazardous materials are other implementations of this concept.

Namaste Greeting Robot
This fun project called ‘namaste robot’ uses an Arduino Uno board at its heart. The Arduino controls several motors simultaneously. The robot turns its head by 180° and scans people in its range using an ultrasonic module. If it finds anyone nearby, it greets the person with ‘namaste’ with both hands pressing together, which is the traditional Indian way of wishing people.

Line Following Robot
Manufacturing plants employ line-following robots with pick-and-placement capabilities. These move on a specified path to pick the components from specified locations and place them on desired locations. Microcontroller AT89C51 does the controlling of the robot. Other components include motor driver L293D, operational amplifier LM324, phototransistor and a few discrete components.

Robocar With Wireless Steering
This next project describes a wireless steered robot. Wireless steering senses the motion and transmits corresponding instruction to control the robot through RF communication. The robot also has an obstacle detection and avoidance system implemented. The accelerometer senses the movement of the steering. Arduino Uno board processes this data and corresponding instructions are transmitted through the RF transmitter to control the robot.

Cellphone-Operated Land Rover
The control of robot involves three distinct phases: perception, processing and action. Generally, the preceptors are sensors mounted on the robot, processing is done by the onboard microcontroller or processor, and the task (action) is performed using motors or with some other actuators. In this project, the robot is controlled by a mobile phone that makes a call to the mobile phone attached to the robot. The tone corresponding to a button is heard at the processing end. The robot perceives this DTMF tone with the help of the phone stacked in the robot.

RF-based Dual-mode Robot
This next dual-mode robot is operated manually using an RF-based remote control. The robot has some inbuilt intelligence to avoid obstacles by changing its path. Further modifications for applications like automatic vacuum cleaner are also available. In such an application the vacuum cleaner will automatically clean the floor, or you can direct it using the RF remote while sitting relaxed on your sofa.

Whisker for Robots
Whiskers for robots are simple switch-type sensors that work like an animal’s whiskers detecting nearby objects in the environment. When disturbed, the sensor sends a pulse to the robot to indicate that an obstacle is present. Sensitive but inexpensive general-purpose whiskers can be made using commonly available steel guitar strings. These strings are very flexible, conductive and easy to use.

Remote Operated Spy Robot Circuit
This next robotics project explains designing a spy robot which can be controlled by the remote. The remote has four switches to control the robot in four directions. The robot senses the surroundings through the charge-coupled device (CCD) camera and sends to the receiver through the Radio Frequency (RF) wireless communication. We have already studied how to establish RF communication in RF Remote Control Circuit for Home Appliances post. This circuit is also designed using such kind of technology.

This project demonstrates the feasibility of creating a window-washing robot for use especially by the handicapped in cleaning residential double-hung sash windows. Under strict weight and size limits it is required to be placed on a window and either autonomously or via remote control clean the outside of a window with no other human intervention. This particular robot moves over the window as if cleaning it, wipes off a series of 12 mm-diameter dry-erase dots, and carries 50 mL of water to simulate the cleaning fluid used in the final device.
