Mobile robots come in all sizes and types – ground, underwater, aerial and legged robots – and constitute an active area of research, development and education. Mobile robots are a simple and inexpensive platform for hands-on multidisciplinary engineering education, as they involve design, mechanical fabrication, sensors, motors/actuators, controllers, and software. Nowadays, many mobile robots are controlled over the Internet, or with mobile phone apps (so called mechatronics). Mobile robots are fun to build and operate, and so are used in schools in many countries to promote STEM (science, technology, engineering and mathematics) education. The FIRST (For Inspiration and Recognition of Science and Technology) Robotics Competition was started by the famous American inventor in 1992 in the USA, and has now become a popular international competition for children of high schools, middle schools as well as primary schools.
TLC mobile robots are designed and developed as examples of innovative product design and prototyping. They are built with representative and impactful real-world social and educational applications, e.g., solar-powered and mobile app-operated lawn mower robot for campus use which can expose students to robotics, smart trash can robot to support Swachh Bharat Mission of a Clean India, and mobile robot racing over the Internet for school children anywhere.
