EmRo: A Raspberry-Pi Emotional Robot

The researchers created a device from several materials that will help to improve and maximize its capacity. Step-by-step instructions and guidance were used to build the device. The robot is divided into two parts: The body and the head which is connected by a magnet. The external structure encompasses the OLED Display and the microphone. While the internal structure encompasses of the the wirings and motors. The microcontrollers were placed inside of the robot’s body. The EMRO’s functionality was determined through test and trials. In terms of speech recognition, the sentence accuracy has a rate of 90% indicating that it has high proficiency in speech recognition. In terms of facial expression analysis has an accuracy of 91%, indicating that it has notable precision and recall. Moreover, the real-time response resulted in a Percentage of Average Time of 43.345%, indicating that the majority of response rates were below the 2-second, suggesting rapid response time. Findings demonstrate that the constructed device’s ability and capabilities were fully examined using various test and trials. The device met the parameters that were set in the study. The feedback received clearly demonstrated that the device’s design was a success.
