Voice Controlled Robot Dog

Abstract

This paper explores the latest advancements in accessible robot construction and voice recognition with the purpose of creating Bobbert Bot, a voice-controlled robot that can be used in education and research. The robot exemplifies key concepts regarding locomotion using wheels and legs, voice recognition, programming microcontrollers, parametric design and fused deposition modeling. Bobbert Bot was designed using open-source technologies and its components were chosen so that the result is functional and affordable. It responds to a set of 9 simple voice commands in English. Its primary method of movement is driving (wheels only), the joints of the legs intervening to help navigate obstacles. It can offer feedback on its status through RGB LEDs and playing situation specific sounds. It is powered by a lithium-ion polymer battery and controlled through two Arduino development boards communicating through the I2C protocol. Its chassis was 3D printed and allows for easy assembly, disassembly and modification.
