The ulv is the land-based counterpart to unmanned aerial vehicles and remotely operated underwater vehicles. unmanned robotics are being actively developed for both civilian and military use to perform a variety of dull, dirty, and dangerous activities. an unmanned land vehicle (ulv) is a vehicle that operates while in contact with the ground and without an onboard human presence. ulv’s can be used for many applications where it may be inconvenient, dangerous, or impossible to have a human operator present. generally, the vehicles have a set of sensors like metal detector, obstacle sensors, etc. to observe the environment, and will either autonomously make decisions about its behavior or pass the information to a human operator at a different location who will control the vehicle through bluetooth operated wireless controller. contents- 1) the suspension system. 2) pick and place arm. 3) wireless module. 4) metal detector. 5) strong metallic body, etc. use- 1) military use 2) coal mines 3) civilian uses 4) radio active places. etc. what’s new! – 1) mechanical suspension. 2) mechanical arm. 3) high torque motors. etc.
