Robot for the physically challenged

In the past decade, robotic applications in human life have made significant progress. However, mobility of robots and user convenience of their control is still a challenge. Utility of robots for a physically challenged person, with practicality and ease of operation, is another issue. In this paper, a robotic solution is proposed for utilization by the physically challenged. A prototype robot is developed using RF signals, with voice control or remote control options. The human voice/remote controlled robot, has obstacle avoidance and edge avoidance features as well. The prototype is useful for applications in diverse fields.
