KRSRI, Kontes Robot SAR Indonesia, is one of the Kontes Robot Indonesia
categories. The robot has a mission to save fire victims into a safe zone, navigate
through broken obstacles, down roads, coral roads. This descriptive observational
study examines the robot's response during field trials. Data was collected by
testing the robot walking in a forward direction, backwards direction, sliding left,
and sliding right, each as far as 50-100 cm. The research also tested the VL53LOX
sensor measurement, testing the robot walking direction using the right wall as a
reference and testing the robot's movement when turning right or left. The reading
of the VL53LOX sensor experienced an error value toward the actual reading was
1 cm to 2 cm. The AX-18A servo motors were in good condition and suitable for use
on a hexapod robot. The servo was able to be connected in a multi-servo
configuration. The servo has been adjusted to carry out a leg movement on the
robot. The linearity test showed that the robot experiences an almost significant tilt
angle error value with an average error value of at most 27.47°. The test is based
on the right wall as a reference. The results obtained by the robot ran stably without
crashing the wall when given a value of sp = 5, Kp = 5, Ki = 0, Kd = 9. In the test
through the broken road, the results obtained by the robot run more stable when
given a value of Kp = 5, Ki = 0, Kd = 3 with a wall boundary distance left and right
of 18 cm. At bypassing the descending and coral stone roads, the robot can walk
stably and slightly rotates right. The error value when the robot turned to the left
tended to be more significant.
