Robotcus took a different approach to control a robot by implementing voice commands instead of traditional methods like pre-programmed routes or joystick control. The robot, based on a Raspberry Pi Zero, interprets voice commands using Google’s speech recognition tool and instructs the motor controllers for movement.
The robot’s design is straightforward, featuring brushed gearmotors for propulsion and a 3D-printed chassis. Initially, the setup was limited to five commands: drive, turn left, turn right, go backward, and “attack,” which activates a flipper from the robot’s past life as a battlebot. However, the Pi Zero faced processing delays, and the wheels lacked sufficient traction.
To address these issues, Robotcus upgraded to a more powerful Raspberry Pi and replaced the chassis for better grip. The enhanced setup allowed for smoother and more responsive execution of voice commands. This project showcases the feasibility of implementing voice control for robots, offering an alternative and interactive method for directing their movements.
