2.0 DETAILED DESIGN

To overcome the challenges given by ABU ROBOCON 2019, KOGAS team came
out with a concept of solution to developed two types of robots which are; 1) a remote-

controlled mobile robot as the MR1 and 2) a four-legged walking robot as the MR2. The
MR1 carries a Gerege from Khangai Urtuu, goes along the zig-zag Forest, crosses the

Bridge before reaching Gobi Urtuu. This robot is equipped with four trans wheels installed

with certain formation to make the robot easier to move at multi-orientation. The robot is
controlled by using a PS3 joystick with Bluetooth communication. The Bluetooth

communication can also be changed to wired communication in case of emergency.

After the MR1 reaches Gobi Urtuu, it will pass the Gerege to the MR2 robot by

using RC Servo mechanism. When the proximity sensor placed at the MR2 robot detects
the signal of the Gerege, it will start walking into the Gobi Area. The MR2 will have to pass

two sharp bends, steps over a 100 mm height obstacle and crossing two ropes to reach

Mountain Urtuu. The four-legged robot was designed with two legs placed close to the body
and another two legs at the outer body. The inner and outer legs will move alternately where

the two legs alternately make steps while the other two legs support the weight of the body.
