Personal robotic assistants help reducing the manual efforts being put by humans in their day-to-day tasks. In this paper, we develop a voice-controlled personal assistant robot. The human voice commands are given to the robotic assistant remotely, by using a smart mobile phone. The robot can perform different movements, turns, start/stop operations and relocate an object from one place to another. The voice commands are processed in real-time, using an online cloud server. The speech signal commands converted to text form are communicated to the robot over a Bluetooth network. The personal assistant robot is developed on a micro-controller based platform and can be aware of its current location. The effectiveness of the voice control communicated over a distance is measured through several experiments. Performance evaluation is carried out with encouraging results of the initial experiments. Possible improvements are also discussed towards potential applications in home, hospitals and industries.Index Terms-smart assistant robot, control over voice, Bluetooth, Android based smart devices.
Smart robotic assistants help human beings in reducing the manual efforts in day-to-day tasks and the risk to precious human lives in hazardous situations. In this paper, we develop a smart robotic assistant that operates on human voice commands, given remotely by using an Android platform based smart IoT device. The real-time signal processing of the voice commands is carried out using a cloud server. The speech command signal converted to text form is then communicated to the robotic assistant over a Bluetooth network. The robotic assistant is developed on an Arduino micro-controller based platform. The robotic assistant is capable of performing different movements such as turns and start/stop operations, and picking up an object from one location and placing it at another location. The effectiveness of the voice commands given over the network is measured through several experiments. Performance evaluation results are encouraging. Potential applications of this smart robotic assistant in homes, hospitals and industries are discussed.
