3.0 MESSENGER ROBOT 2 (MR2)

The MR2 needs to be developed automatically. The way to move is to have four legs
like a horse. Many pedestrian methods have been tried in the MR2 development process.

Among the methods are using a servo motor with spiders such as spiders and movements
using a servo motor have been used for horse-like movements. The use of servo motors for

speeding purposes is highly inappropriate due to the slow movement. In addition to slow

movement, great challenges are also encountered in securing movement stability.

After the trial of servo testing fails to reach our goal, we explore using different types

of motors for leg movements. The first motor used is the DC geared motor. The challenge

we encounter is maintaining the feet in one of the pre-determined positions. This problem
can be solved by using a power window motor with a geared worm.
