Abstract

Human activity has been increasing, to support the activity, people in the modern era create robots to replace some human activities. The interest in two-wheeled balance robots has continued to increase, this is because it is highly maneuverable, making it efficient for use in various areas. In this study, the online navigation of a two-wheeled self-balancing robot is done. The connection between the robot and online navigation is using a Wi-Fi connection. The world model base on the real room is created by Gazebo and then visualized in RVIZ. The map creation and navigation process are handled by the package provided by ROS. The results of the simulation and real tracking show that the robot can move from the starting point to the destination point in either a straight or a curved path. The difference of the final position of the robot between simulation and real tracking is only (15.4 cm, 4 cm) and (9.6 cm, 43 cm) for the straight and curved path. This result proved that online navigation can be used to navigate an autonomous robot without real navigation sensors.

Abstract

The purpose of this prototype is to enhance communication between stroke patients and their caregivers, as difficulty in understanding the nuanced wishes of stroke patients often leads to a reduced quality of life for the patients and increased caregiver depression. This study aimed to address these challenges by providing a more effective means of interpreting the desires of stroke patients during their interactions with their caregivers. The prototype utilizes a dual-input system to capture the intricate communication dynamics. The first input involves recording the finger movements of the patient through touch interaction with the TTP223 touch sensor area. In contrast, the second input comprises a time-step phrase that serves as a complementary mechanism for selecting communication phrases. The combination of these inputs is processed using Boolean logic, specifically employing basic AND logic, in which both inputs must register as high to yield a correspondingly high output. The ESP32 microcontroller processes the output signal, and the resulting information is displayed on both an LCD screen and a dedicated Telegram application. The prototype achieved a notable accomplishment of 100% accuracy in reading inputs.
