Development of an AI-Powered Humanoid Robot for Assistive and Collaborative Applications in Education and Industrial Automation

AbstractHumanoid robots that can move through a space, respond to spoken questions and represent an organisation to thepublic are an increasingly common bridge between robotics research and everyday institutional use. This paper reportsthe design, fabrication and field evaluation of an AI-powered humanoid robot developed as an interactive campusinformation assistant. The robot's body was modelled in SolidWorks and additively manufactured in two ABS sectionsthat were bonded, puttied, sanded and painted to a finished shell; mobility is provided by 12 V DC geared motorsdriven through a Cytron 10 A motor controller and powered by a 12 V, 8000 mAh lead-acid battery, with motioncommanded wirelessly over a FlySky FS-i6 six-channel, 2.4 GHz (AFHDS 2A) radio link. A rechargeable publicaddress speaker gives the robot a voice, while an AI/NLP-based assistant answers spoken or text queries about theinstitution's academics, admissions, placements, facilities and events, drawing on a curated knowledge base offrequently asked questions. The complete platform was validated through bench testing of its locomotion (forward,reverse, left/right turn, stop) and through a three-day public demonstration at the “Vignana Mela 4.0” exhibition (17–19 February 2025), where it was operated continuously by student volunteers and answered visitor questions in realtime. The results show reliable remote-controlled mobility, stable battery-backed operation, and consistent, correctlyspoken responses to the pre-configured question set, with positive visitor feedback. The work illustrates a practical,low-cost route from mechanical design and embedded control to a deployable human-robot interaction platform, andidentifies autonomous navigation, open-domain dialogue and multilingual support as the next steps toward broaderassistive, industrial and public-safety use.
