Abstract In an industrial company today, robotic arm is commonly use to perform a specific
task or work. For the robotic arm’s part that going to focus in this project is at the gripper which
will operate with an electrical motor that attach to it. Robotic arm gripper usually can be two
type of operation, which are automatic and manual. In this project, It will be in a manual
operation to operate the gripper by using three types of joystick sensors for the input. It also
have an interface of this project with personal computer for coding and visualization. Joystick
sensors need a wider range of resolution to control and give more position or angle rotational
for robotic arm gripper and also need force sensor to prevent the grasping gripper from
excessive force which could crush or dent a workpiece. This project will examine and make
comparison with the three types of joystick sensors by its resolution or range of input voltages
to the microcontroller can be produce for controlling the robotic arm gripper. This robotic arm
gripper also has a force sensor which will be use to measure amount of force and set the limit
for the grasping gripper at the work piece. The types of joystick sensor that will be use in this
project are potentiometer, hall-effect and inductive while the type of force sensor that will be
use is force sensitive resistor. This project will be link to Arduino serial monitor and plotter
and the result shows the resolution of the joystick sensors and amount of force for force sensor.
Mostly joystick has two axes which are x and y but some has only one axis which is x. In this
project, it will be only use one axis as the gripper will be operate with only one electrical motor.

Keywords joystick sensors, force sensor, robotic arm gripper, Arduino, potentiometer, hall-
