Mark 2 is the ameliorated, enhanced and superior version of Mark 1. This steel structured, lead acid battery powered and Arduino MEGA controlled robot walked with higher efficacy and simpler algorithm possessing a set of ankle motors. Initially, the servos didn’t respond as per the expectations, following which the power supply design system was detected with certain problems. To mitigate these, a central power supply design board was made that controlled the Arduino power as well.

Yet, the system, did not maintain proper balance by itself due to insufficient length of the bot and hence the bot length was increased.
