In many instances, the orientation of the robotic platform does not change and hence for those applications, it is desired to have platforms which just have translational degrees-of-freedom and does not have rotation about the vertical axis (yaw rotation). In this paper, the authors propose two architectures of the platform that have two active and two passive wheels. Simulation in V-REP software was carried out and physical prototypes were developed and tested to validate the effectiveness of the proposed platforms. One of the proposed design fits perfectly for a pure translation mobile platform.

They can be manually controlled using devices such as joysticks or by using mobile phone applications, through Bluetooth or similar technologies. In this paper, the authors propose usage of Leap Motion device which can track hands of human users. By using the gestures, the human can operate a mobile robot. For the demonstration, the authors propose its usage on a 3 Omni-wheel based mobile platform. First, the mathematical model of the robot was formulated and simulated in V-REP software for various types of motion. Then, a physical prototype was developed, which was integrated with both Bluetooth based mobile phone application and Leap Motion device. Field trials and survey of 30 people was carried out, where both methods were perceived to be of similar ease of use and intuitiveness. However, the authors feel the results of Leap Motion control may improve with subsequent usage by the users.
