    (Research and Development Wing, MIST, 2023-12) Baki, Ramisha Fariha; Akhtaruzzaman, M.; Refat, Tahsin Ahmed; Rahman, Mouneeta; Razzak, Md Abdur; Majumder, Md Mahfuzul Karim; Islam, Md Adnanul; Ferdaus, Md Meftahul; Rahman, Muhammad Towfiqur; Naveed, Quadri Noorulhasan
    A cognitive humanoid head is an AI enabledhead-bot platformthat resembleshuman's cognitive abilities, such as perception, thinking, learning, and decision-making. The platformis able tointeract with human throughnatural language processingand recognizeindividuals, thusallowing seamless communication between two parties. No such cognitive platform has been introduced inBangladesh,thuscreatinganopenfieldtocontribute to the field of Machine Intelligence.Thisstudy aims to develop an AIbased humanoid head (head-bot) capable of imitating arange of expressions, recognizing individuals, and interacts with visitorsthrough general conversation.The head-botskeleton is developed using a number of hexagonal blocks of PVC sheet to mimic a human-head-like structure where LCD, camera, microphones, and speaker are mounted. Twoseparate Machine Learningmodels are designed for face detection andrecognitions, and voice enabledchat-bot implementation. The head-botplatform incorporates 2-DoF neck movements for various head gestures and face tracking.The Artificial Neural Network models are tested with accuracy of , and , for face detection andrecognitions, and speech recognitionsand response generation, respectively. According to the overall results and system performances, it seems that the proposed system has a number of good potentialsfor real life applicationssuch as entertainment, guidance, conversations, interactive receptionists, personal companion, medical assistance, and so on.
