Drive a robot car with nothing but your voice

Traditional control of RC cars and other small vehicles has typically relied on some sort of joystick-based solution, often with one to adjust direction and the other for speed. But YouTuber James Bruton wanted to do something different: create a completely voice-driven go-kart.

Its solution is based on Deepgram's voice recognition service, which allows users to send small snippets of audio samples to its cloud via an API and receive responses with a transcription of what was said . As for the kart itself, its frame was created by first welding together several steel tubes and attaching a thick plywood base on top. The front cutout allows a large caster wheel to turn left or right using a chain driven by a repurposed wiper motor assembly. The absolute positioning of this wheel was obtained by measuring the tension of a potentiometer which rotates with the chain. And finally, a pair of hub driven wheels, similar to those found on hoverboards and scooters, have been placed at the rear for propulsion. Each motor was connected to its specific driver, and in turn, was connected to an Arduino Uno.

When the user wants to move in a certain direction or change their speed, all they have to do is speak into the supplied USB microphone which allows a Raspberry Pi to receive a transcript and transmit a command to the user. 'Arduino. As seen in the video below, Bruton's voice-activated go-kart is a joy to use, although a little dangerous too.
