The project was intended to use local equipment's to make an UGV that can climb stairs. The design, Construction and Control Systems all were carried out using the scare local equipment's in Level-03, Term-01. The project was mainly Inspired by the US military robot ''Foster-Miller TALON''. The technology developed by the U.S. Army Tank Research, Development and Engineering Command's, (TARDEC), Tank and Automotive Research Center currently allows UGVs to be operated via the Internet using a cellular data signal. Operators are able to log into the Long Distance Tele-Operation, (LDTO), system via a secure Web portal. Once connected, the operator selects a platform from a drop-down menu and is directed to a user interface screen that includes a variety of commands and a video link with the platform.

Operations like radioactive waste handling, bomb disposal, surveillance, search and rescue are today performed mostly by humans at great risk to their own safety and well-being. In order to minimize direct human intervention in such operations, the design of a remotely operated versatile Unmanned Ground Vehicle (UGV) mounted with a robotic manipulator . The robustness, range and security of the communication link between the remote base station and the robot, obstacle avoidance and the real time control of the robot are some of the major issues encountered while deploying such robots in the above scenarios. An UGV, mounted with an extend part at the front, can be used for climbing and overcoming obstacles like stairs and thus help in search and rescue type operations. The robot can be equipped with sensors and camera for obstacle detection and avoidance. The camera can also be used to send the visual information back to the base station in real-time, allowing accurate control of and monitoring over long distances. Along all of these The US military robot “I-ROBOT” also inspired us to do so. Due to time and financial constrains gripper and camera are not used in this robot.
