The underground building environment plays an increasingly important role in the construction of modern cities. To deal with possible fires, collapses, and so on, in underground building space, it is a general trend to use rescue robots to replace humans. This paper proposes a dual-robot system solution for search and rescue in an underground building environment. To speed up rescue and search, the two robots focus on different tasks. However, the environmental perception information and location of them are shared. The primary robot is used to quickly explore the environment in a wide range, identify objects, cross difficult obstacles, and so on.The secondary robot is responsible for grabbing, carrying items, clearing obstacles, and so on. In response to the difficulty of rescue caused by unknown scenes, the Lidar, inertial measurement unit and multiview cameras are integrated for large-scale 3D environment mapping. The depth camera detects the objects to be rescued and locate them on the map. A six-degree-of-freedom manipulator with a two-finger gripper is equipped to open doors and clear roadblocks during the rescue. To solve the problem of severe signal attenuation caused by reinforced concrete walls, corners and long-distance transmission, a wireless multinode networking solution is adopted. In the case of a weak wireless signal, the primary robot uses autonomous exploration for environmental perception. Experimental results show the robots' system has high reliability in over-the-horizon maneuvering, teleoperation of the door opening and grasping, object searching, and environmental perception, and can be well applied to underground search and rescue.

Di era modern ini pengiriman data secara wireless sangat diperlukan dalam berbagai bidang, salah satunya pengiriman data pembacaan sensor. Penelitian ini menggunakan DHT11 sebagai sensor suhu dan Raspberry Pi sebagai pembaca data sensor dan pengirim data hasil pembacaan sensor menuju Android secara serial. Pemrograman yang dilakukan dalam penelitian ini menggunakan bahasa pemrograman Python dan menggunakan Bluetooth sebagai transmisi data secara wireless. Hasil dari penelitian ini berupa rancangan sistem pengiriman pembacaan data sensor suhu secara serial yang dapat dibaca oleh Android. Rancangan sistem yang dibuat sudah dapat mengirimkan pembacaan data sensor dengan jarak jangkauan sejauh 10 meter.

“…This robot has a purpose or primary mission to spy on dangerous condition so that it can directly view the condition and avoid the casualties. This robot is controlled by wireless system using radio control as a telecommuting [4]. It is also equipped with audio and video systems which are emitted through Wi-Fi (Wireless Fidelity) wave [5] so the movement of the robot becomes more extensive and flexible.…”

Designing and manufacturing / prototyping surveillance robot that has self-protection mechanism by using nail gun with VDI (Association of German Engineers) method, aims to design and create a robot that capable to conduct reconnaissance missions and protect themselves as well as immobilize the target object. The prototype robot is able to send data in the form of audio and visual through Wireless system by using Wi-Fi (Wireless Fidelity). The robot is equipped with self-protection system such as nail gun that can move in rotation and elevation, it is such an effective weapon to paralyze the targets objects if necessary. This robot is designed to maneuver on the field that has tilt angle up to 30o. Based on the test results, the robot is able to maneuver with speed 2.88 km/h on duration more than 30 minutes and be able to pass the field angle of 35o. Proximity sensors which are used as indicators of arm robots position works well on the pitch and yaw motion. Security system that is designed to shoot also works well. The most effective control radio frequency used is 2.4 GHz and the data sender system frequency is 5.8 GHz.
