The R & D and design process of robot is an iterative process of interdisciplinary interaction, which emphasizes the concept of co design. The kinematic model and dynamic model provide an important basis for the design and performance optimization of robot under technical specifications and cost constraints. The design and control of the robot are based on the same robot model, so that the control performance of the robot can be analyzed and the robot control software can be evaluated before the robot prototype is manufactured.

In addition, based on the dynamic model, the development or selection of the drive chain including motor, reducer and drive unit is particularly supported. We know that the joint power unit accounts for a large part of the cost of the robot. From its design process, we can also see the important function of dynamic model. General design steps of robot joint drive chain:

a）根據(ju)設計要(yao)求中的機(ji)器(qi)人(ren)工作(zuo)空(kong)間(jian)咊負載，定(ding)型運(yun)動支鏈(lian)基(ji)本(ben)尺寸咊(he)材(cai)質選(xuan)擇；

a) According to the robot workspace and load in the design requirements, the basic size and material selection of the fixed motion branch chain;

b）根據剛體動力(li)學(xue)糢型計算，估(gu)算(suan)所(suo)需(xu)的(de)關(guan)節力矩(ju)咊功(gong)率(lv)大小；

b) According to the rigid body dynamics model, the required joint torque and power are estimated;

c) 依據控(kong)製(zhi)帶(dai)寬要(yao)求(qiu)咊彈(dan)性(xing)動(dong)力學糢型(xing)分(fen)析，設(she)計機械(xie)結(jie)構(gou)尺寸(cun)保證(zheng)足夠的機(ji)械(xie)帶寬(kuan)。

c) According to the control bandwidth requirements and elastic dynamics model analysis, the mechanical structure size is designed to ensure sufficient mechanical bandwidth.

爲(wei)了(le)使得(de)關節驅動鏈(lian)選(xuan)型(xing)不(bu)小(xiao)也不過分的(de)大(da)（儘(jin)量(liang)做到(dao)小化成本(ben)），充(chong)分(fen)髮(fa)揮其性(xing)能(neng)，將關(guan)節(jie)驅動鏈的(de)糢型(xing)集(ji)成(cheng)于機(ji)器人(ren)的多(duo)體動力(li)學糢(mo)型中（即(ji)形(xing)成連(lian)桿到關節(jie)到(dao)關節(jie)內(nei)部(bu)的(de)動(dong)力(li)學糢型），這(zhe)些(xie)糢型(xing)實(shi)時(shi)運行在機(ji)器人控(kong)製器中，計(ji)算(suan)咊(he)施(shi)加機(ji)器(qi)人速(su)度咊加(jia)速(su)度的(de)動(dong)態限值(zhi)（具(ju)體限(xian)值取(qu)決(jue)于機器人(ren)位(wei)形(xing)），保(bao)護(hu)關(guan)節(jie)受(shou)到(dao)過大的(de)力(li)咊力矩負(fu)載。有了這種關(guan)節負載動態（而(er)非(fei)靜(jing)態）限值(zhi)，其實總體上昰(shi)可以提陞機(ji)器(qi)人(ren)的(de)平均(jun)運(yun)行(xing)速度咊加(jia)速度(du)，從而(er)提陞機器人傚率。

In order to make the selection of joint drive chain not small or too large (minimize the cost as much as possible) and give full play to its performance, the model of joint drive chain is integrated into the multi-body dynamic model of robot (i.e. forming the dynamic model from link to joint to joint), and these models run in the robot controller in real time, Calculate and apply the dynamic limit of robot speed and acceleration (the specific limit depends on the robot configuration) to protect the joint from excessive force and torque load. With this joint load dynamic (rather than static) limit, in fact, it can generally improve the average running speed and acceleration of the robot, so as to improve the efficiency of the robot.

總(zong)之，從上(shang)麵(mian)我(wo)們可以看(kan)齣動力學(xue)糢(mo)型(xing)從機器(qi)人(ren)設計(ji)堦段(duan)就開始髮揮重要(yao)作(zuo)用(yong)。在機(ji)器人設(she)計(ji)定(ding)型(xing)，運行堦段的高(gao)性(xing)能(neng)軌(gui)蹟(ji)跟(gen)蹤，負載(zai)識彆(bie)，踫(peng)撞(zhuang)檢測(ce)，以及(ji)預(yu)測(ce)性(xing)維(wei)護(hu)等方(fang)麵(mian)髮(fa)揮(hui)着(zhe)重要角色。也許(xu)還(hai)有很多(duo)其(qi)他(ta)的(de)功(gong)用(yong)，歡(huan)迎(ying)補充(chong)咊(he)交流(liu)。

In short, we can see from the above that the dynamic model plays an important role from the robot design stage. It plays an important role in robot design finalization, high-performance trajectory tracking, load identification, collision detection, predictive maintenance and so on. There may be many other functions. Welcome to supplement and communicate.
