5. Experimental procedure
First calibrate the UGV movement (moving and turning), in this case calibrate the real signal comes from
encoder on UGV with the parameter in simulink model. For example when UGV moved forward one
meter how much signal read by encoder in simulink or when UGV rotate how much signal that represents
90o
degrees rotation in reality. From there the accuracy of encoder to the real condition revealed and can
be setup to simulink model. This UGV use only relative localization for knowing its local position.
Odometry method were used here, where encoder act as a sensor to solve it.
Then place the real UGV and UGV model in the same coordinate for starter. After that, turn on the
UGV and also run the simulation. Drive UGV through obstacle from the field to the finish spot without
touching the field wall. After the UGV reach the finish spot, repeat it for different field and after the
experiment finish, stop the software simulation and turn off the UGV.
