Design and implementation of an open-source, low-cost remote-controlled tiny humanoid robot for accessible robotics applications

Abstract This paper presents the design and implementation of Jaeger UTFPR, an open-source, low-cost, remote-controlled tiny humanoid robot measuring just 12 cm in height. Developed with a focus on accessibility and affordability, the robot integrates 3D-printed components, cost-effective electronics, embedded systems, and wireless communication to provide real-time audio and video feedback through a virtual reality (VR) interface. Operators control Jaeger UTFPR using a VR headset and motion controllers, enabling immersive telepresence and direct manipulation of the robot’s movements. With a total cost of just a few tens of dollars, this innovative solution offers broad applications in education, entertainment, research, and remote inspection, serving as an accessible platform for robotics enthusiasts and developers. Experimental evaluations demonstrate the system’s effectiveness in balancing performance and cost, validating its potential as a tool for immersive robotics experiences.
