Sphero Droid - Pendulum Based Spherical Robot

Abstract

Considerable amount of researches are being done on mobile robot from last century, over different
aspects like control, motion, sensing, and many more. In terms of motions various designs are available from usage of
limbs or actuators. For a spherical robot, it possesses various advantages in terms of motion, navigation. A spherical
robot also offers almost zero friction due to very unique property of sphere i.e. single contact point. But by using
rolling motion, a limbless robot can be made. The rolling motion is created by use of rotation done by sphere. This
leads us to the development of the Spherical Mobile Robots. These spherical robots possess various advantages in
terms of motion, strength, and ease of motion over rough terrine. The spherical shaped robots can also be made gas
and liquid proof depending over situations.
This paper is about design and development of a spherical robot (termed ‘Sphero Droid’) using pendulum principal.
Presently droid is controlled with help of remote.
