We have used a Bluetooth HC module on the Arduino as a master receiver on the
MR1 bot. After configuration, ps2 controller works as a slave Bluetooth device and keeps
sending data to the Arduino so the bot can be controlled within the calculated range using
ps2 controller. This gives us a better experience in controlling as long as Bluetooth module
can provide stable transmission of data without any delay.

2.2.1 Mechanical Design
The MR2 is a fully automated robot which moves on four legs. Each leg has three
joints driven by a servo. While walking, one of the leg will be in the air and other three will
stay on the ground for support. This motion is repeated with the other legs. The motion
resembles how a spider walk. The bottom part of the leg is designed to be bent so that it can
withstand the weight of the robot. Every part of the MR2 is printed out using PLA filament.
