The second version of Yesaji 2.0 used a more tried-and-tested design, consisting of a four-wheel drive machine armed with a golden disc, spinning vertically at 7500rpm at the front of the robot. The robot was also capable of running inverted on two of its wheels, albeit without the use of its weapon. The robot was largely coloured white, but was decorated with a brick wall design across its front Armor panels.

The robot was named after YesajiKank, a childhood comrade of Shivaji Maharaj, a warrior king and the founder of the Maratha Empire.
