Robotics

 

This is a workshop designed for beginners and robotics enthusiasts. They would be introduced to the basic fundamentals of robotics and will learn to apply them in real life. Hands-on sessions will help them understand the practical aspects too.

The workshop would help them to enter the world of robotics and to create an aptitude in the limitless field of robotics. The workshop will help them to get the feel of robotics and how powerful and exciting it can be.

 

DAY 1: Wired Robotics

In this session basic perception of robotics at university level is developed in mind of students

 

INTRODUCTION

Robots

Robotics Procedure of building robots

Constituents of any robot

In this session basic idea of robots and robotics is made clear. Participants are introduced to process of building machine/robots and members share their experience of building machine.

 

LOCOMOTION

Wheeled

Legged

Climbing

Flying

Floating

Details on various modes of locomotion like wheeled, tracked, legged, flying etc is given to participants. More focus is given to wheeled and tracked robots, as they are most common and preferred. In these concepts of vehicle, dynamics are made clear like effect of center of mass, payload on robot etc.

DURATION

We conduct workshops on two consecutive days. Each day has an eight hours session (in total 16 hours). This is properly divided into theory and hands-on sessions. In the end we organize a Robo-racing & Robo-Soccer competition among the participants of the workshop so that they get real feel of competitive environment.
