Abstract
Skripsi ini membahas mengenai perancangan kursi roda model mini yang dapat
menyeimbangkan dudukan kursi roda dilengkapi dengan fitur mengikuti garis dan
dapat dikendalikan melalui smartphone. Perancangan kursi roda model mini
dilakukan untuk membuktikan konsep yang penulis rancang sehingga kursi roda
model mini dapat dirancang dengan skala yang sama dengan kursi roda pada
umumnya untuk meringankan pekerjaan tim medis dalam usaha merawat pasiennya
dan meningkatkan kenyamanan pengguna kursi roda saat berhadapan dengan
permukaan miring. Kursi roda model mini dilengkapi dengan platform sebagai
dudukan kursi roda menggunakan kontrol PID sebagai kontrol keseimbangannya.
Dudukan kursi roda model mini dirancang dan dimodifikasi menyerupai kursi
dengan menggunakan bahan akrilik yang disatukan dengan servo motor MG996R
sebagai aktuator. Fitur pengikut garis dan dapat dikendalikan smartphone melalui
bluetooth dikontrol oleh mikrokontroler ESP32. Dalam perancangan kursi roda
model mini, dibutuhkan beberapa komponen penting seperti mikrokontroler
Arduino Uno, mikrokontroler ESP32, servo motor, sensor accelerometer dan
gyroscope, sensor inframerah, dan motor DC. Penulis menggunakan metode tuning
Ziegler-Nichols untuk memperoleh parameter PID yaitu: Kp, Ki, dan Kd. Arduino
Uno diprogram untuk memproses pembacaan accelerometer dan gyroscope yang
dibandingkan dengan referensi sudut sebagai informasi untuk menggerakkan servo
sedangkan ESP32 diprogram untuk memproses pembacaan dan perintah yang
diperoleh dari modul inframerah dan joystick dari aplikasi Blynk. Hasil yang
diperoleh dari kursi roda model mini adalah nilai Kp = 1.2, Ki = 9.6, dan Kd = 0.1
pada sumbu X dan nilai Kp = 3, Ki = 30, dan Kd = 0.075 pada sumbu Y dengan
metode Ziegler-Nichols. Penulis memperoleh keseimbangan kursi roda model mini
dengan hasil dudukan horizontal setelah 2 detik. Selain itu, penulis juga melakukan
pengujian terhadap beberapa sudut kemiringan untuk mengetahui respons sistem
kontrol saat tidak diberi beban maupun diberi beban 1800 gram. Hasil sistem
balancing membutuhkan waktu rata-rata 2 detik untuk sumbu X dan sumbu Y untuk
menyeimbangkan dudukan. / This thesis discuss the design of mini wheelchair that can balance the wheelchair
seat equipped with line follower feature and can be controlled via smartphone. The
design of mini wheelchair model is done to prove the concept that the author
designed so that the mini wheelchair can be designed on the same scale as a
wheelchair in general to ease the work of the medical team in caring its patients and
increasing the comfort of wheelchair users when dealing with sloping surfaces. The
mini wheelchair model is equipped with a platform as a wheelchair seat that uses
PID control as the balancing control. The mini wheelchair seat is designed and
modified to resemble a chair using an acrylic material which is combined with the
MG996R servo motor as an actuator. The line follower feature and smartphones
controllable via bluetooth is controlled by ESP32 microcontroller. In designing a
mini wheelchair model, several important components are needed, such as the
Arduino microcontroller, ESP32 microcontroller, servo motor, accelerometer and
gyroscope sensors, infrared sensors, and DC motors. The author uses the Ziegler-
Nichols method to support the mini wheelchair model by obtaining the PID
parameters, namely: Kp, Ki, and Kd. The Arduino is programmed to process
accelerometer and gyroscope readings compared to the angle reference as
information to drive the servo motor while ESP32 is programmed to process
readings and commands obtained from the infrared module and joystick from Blynk
application. The results obtained from the mini wheelchair model are the values of
Kp = 1.2, Ki = 9.6, and Kd = 0.1 on the X axis and the values of Kp = 3, Ki = 30,
and Kd = 0.075 on the Y axis using Ziegler-Nichols method. The author obtained a
mini wheelchair balance with a horizontal seat after 2 seconds. In addition, the
author also tested several tilt angles to determine the response of the control system
when neither loaded nor given a load of 1800 grams. The result of the balancing
system takes an average of 2 seconds for the X-axis and Y-axis to balance the stand.
