Heavy payload forging manipulators are mainly characterized by large load output and large capacitive load input. The relationships between outputs and inputs have greatly influenced the control and reliability. Forging manipulators have become more prevalent in the industry today. They are used to manipulate objects to be forged. The most common forging manipulators are moving on a railway to have greater precision and stability. They have been called the rail-bound forging manipulators. In this paper, one presents the general aspects of a rail-bound forging manipulator, like geometry, structure, general kinematics and forces of the main mechanism from such manipulator. The kinematic scheme shows a typical forging manipulator, with the basic motions in operation process: Walking, the motion of the tong and buffering. The lifting mechanism consists of several parts including linkages, hydraulic drives and motion pairs. An idea of establishing the incidence relationship between output characteristics and actuator inputs is proposed. Self-forging systems have the ability to achieve an open, fast, direct forging of products that are often heavy and heavy but also bulky. Open forging productivity is generally very high, it is determined not only by the capacity of forging press but obviously dynamic handling by forging manipulator. The most prominent and qualitative forging machines are the DANGO and DIENENTHAL series, equipped with high dynamic devices and specially designed to operate on heavy forging presses. They ensure the reliability and repeatability of all forging cycles. Even a modernization of existing forging machines with D&D machines will improve the capacity and quality of these facilities. D&D handlers allow to forge nearly clean shapes and guarantee superior surface qualities, thus saving energy, improving production and saving costs during the machining of parts. Savings due to shorter process times and reduction of reheating cycles result in shorter recovery time.

Here we have to mention that all these SF writings and many others that have existed over time, especially in the 20th century, have influenced alongside obvious screenings, young people and not just them, to think more about our role, robots, into a better world. The robot's key role is to help the man make his work easier, safer, more enjoyable, just like a computerized machine that helps us work faster and better, the robot has an obvious role in making work easier, to work in our place when we are tired, when work is exhausting and repetitive, when the environment is toxic, hostile, dangerous and in many other situations. However, it is time to say that the role of the robot in the future is altogether another, namely, to help us conquer the cosmic space to expand ourselves as a race in the whole universe in which we are now. In fact, this is the robot's humanitarian role and in the future, it can be developed and prepared just for that purpose. Exploratory robots are robots that operate in hard-to-reach and dangerous locations, telegraph or partially autonomous. They can work for example in a region in military conflict, on the Moon or on Mars. A geared navigation on the ground in the last two cases is impossible due to distance. Communication signals arrive at their destination in a matter of hours and their reception lasts as long. In such situations, robots have to be programmed with several types of behavior, from which they choose the most appropriate and execute it. This type of robot equipped with sensors was also used to research pyramid wells. Several cryobots (cryo robots) have already been tested by NASA in Antarctica. This type of robot can reach up to 3,600 m through the ice. Cryobots can thus be used in polar head research on Mars and Europe in the hope of alien living. NASA has always said that understanding how to live and work in space for long periods of time has been a key goal of the International Space Station. But, from the White House, it may seem expensive this race around the Earth, considering that the mission costs about $ 8 million a day. Space makes us anxious. We are anxious that things go smoothly as if space flight should be infallible like a flight to London. And we are looking forward to a return on investment. We fly in space because of human ambition, because nothing gives us more resistance than trying to do what we have not done before. And we're flying in space because space is the eighth continent. We may eventually need asteroid or lunar resources, depending on how we manage the resources we have here on Earth. Eventually, we should become a species that will conquer other planets, whether we are no longer inside or that we actually destroy it or it will be destroyed.

“…e evolution of the settlement has been grossly investigated (e.g., [5][6][7][8][9][10]), while prediction models have also been developed for capturing the development of the subgrade settlement (e.g., [11][12][13]). However, each study is based on their own soil type so that the availability settlement prediction model may be limited, as the heterogeneous filed sediments consist of various soil types interlayered at random [14,15]. Although Terzaghi's conventional linear onedimensional model [16] can be adopted to predict the ultimate primary consolidation settlement for the foundation, the in situ consolidation is a three-dimensional problem with varying coefficients of consolidation [15,17].…”

Monitoring the settlement of high-fill subgrade plays a significant role in maintaining the service quality of highways. To investigate the postconstruction settlement of high-fill subgrade under gravity stress and vehicle loads, in situ monitoring was carried out on the Lanzhou-Yongjing highway. Single-point settlement meters were buried in various depths under the driveway and road shoulder. The evolution of settlement with time and space was analyzed. The results show that the settlement of the road shoulder is greater than that of the driveway; the settlement of the subgrade increases with time and tends to be stable after 1 year; the vehicle loads have no big effect on the settlement of the subgrade; the exponential model can be adopted to predict the settlement of the Lanzhou-Yongjing highway accurately.
