1. Introduction to the work
1. Creative background and motivation
Since entering the 21st century, human society has developed rapidly, and all walks of life have increasingly urgent needs for stable transportation. It’s getting higher and higher. In our daily lives, we often encounter unexpected events, such as an elderly person accidentally suffering a limb fracture, unexpected road accidents, etc. In these events, higher requirements are put forward for the rapid and safe transportation of injured people, and now At this stage, social medical emergency transportation equipment is still far from Sierra Leone Sugar and does not meet this standard, especially in terms of stable transportation. In terms of military ammunition material transportation, as the proportion of new military ammunition in the new century in the ammunition of the three armed forces of various countries continues to increase, the demand for their stable transportation is also increasing. In terms of earthquake relief, due to the special situation with a large number of injured people, there are also high requirements for the rapid, intelligent and stable transportation of injured people. Faced with the above various demands, we proposed to design a transportation robot that can achieve stable transportation Sierra Leoneans Sugardaddy. Solve the above problems and meet the needs of all aspects for stable transportation.
2. Performance characteristics of the work
In today’s era, logistics is developing rapidly, and transportation capacity has become an important indicator to measure a country’s strength. Nowadays, most of the SL Escorts transportation in the air adopts traditional transportation methods. In the face of some situations that require stable transportation, traditional transportation methodsSierra Leone Sugar DaddyThe law falls short of the request. Sierra Leone Sugar Daddy The “structure-changing intelligent service robot” designed this time can collect the three-dimensional tilt level of the load in real time through the inclination sensor. The relevant information is then processed by the MCU, and then the servo motor is driven to change the structure of the robot itself, thereby adjusting the tilt level of the cargo-carrying plane, and finally achieving the stability of the cargo-carrying plane. Sierra Leoneans Sugardaddy reaches the request of stable transportation.
In addition, the “structure-changing intelligent service robot” combines the advantages of wheeled robots and foot-type robots, and can change the bending degree of the “legs” in real time according to different surrounding conditions. At the same time, quadruped robots are more stable than biped robots and avoid the redundancy and complexity of hexapod robots. Also, because of their excellent mobility, they can maintain the load surface at all times. In this way, the items are always in an ideal and stable state during transportation, which greatly reduces the collision between items and their own vibration, thereby avoiding unnecessary losses.
Finally, this work uses inclination sensors and servo motors to adjust the height of each support point of the robot in real time to achieve the stability of the three-dimensional object-carrying object under different road conditions.
3. Works Its commercial and practical value

If it is used in medical emergency, it can significantly improve the level of emergency services of medical institutions and reduce the need to a great extent.During the transportation of patients seeking emergency care, uneven roads cause vehicle instability, causing unnecessary pain to the patients. Especially for the spineSierra Leone SugarstrictSierra Leoneans EscortWhen there are special requirements for the transportation of seriously injured and other special patientsSL Escorts, the “structure-changing intelligent service robot” The applicability and commerciality will become more obvious.
In daily life, “structure-changing intelligent service robots” also have broad application prospects. For example, using “structure-changing intelligent service robots” as carrier systems to create highly stable strollers can It is a good solution to the problem of instability of traditional strollers on uneven roads Sierra Leone Sugar Daddy, and this method is better than traditional strollers to reduce The vibrator method solves this problem and can give the baby a more comfortable surrounding environment, which can greatly improve the practicality and commercial value of the stroller.
