Robot kinematic &dynamics definitions

Robot construction &Kinematic and Dynamic analysis meaning.

To follow the series of my videos that I explained the fundamentals of designing a robot manipulator that we can use it in our daily life applications. In this video, I explained some additive points that we have to obey them in order to design our own mechanism. Firstly, I define the meaning of basic elements in robot manipulator which are the linkages are set of links connected by joints, the actuator is an element attached to joints to give a suitable motion to all links, transmissions are the elements using to transmit power, in between linkages like gears, and pullies, controller and sensors are the elements which used to provide intelligence to control the whole system, the user interface is the element which used to help the user to display robot operating conditions. Furthermore, to form the final shape of the robot manipulator, after getting the exact task and workspace of it, there will be infinite shapes that engineers can follow to form that mechanism. In this case, I suppose to design a mechanism that will be used to cut some of the plastics in an application so that I explained to optional mechanisms that can be applied in that manner. Finally, I give a brief explanation about the aim of doing kinematic and dynamics analysis of robot manipulators and what are the meanings of that. In position analysis, we try to reach and control the position and orientation of the end effector of a manipulator, in velocity analysis we try to reach and control the rate of joints of the actuator, and linear velocity of the end effector respectively, acceleration and torque analysis are used help us to specify the torque that we need to apply during robot working and to help us to select the suitable actuator that we need it to actuate the system.

إصنع كمامتك بنفسك

خواتمكم مباركة,

نظرا للوباء القاتل الذي هجم على العالم في عشية وضحاها (فايروس كورونا) وتوجه العديد من الشركات العالمية للبحث عن مايردع هذا الفايروس منها في المجالات الطبية ومنها في المجالات الهندسية وغيرها من المجالات .

أردت اليوم أن ألخص لكم في هذا المقال أهم جزء من هذه المكافحات والتي تعد خط الدفاع الأول للوقاية من فايروس كورونا بحيث  تنعدم في بعض المناطق منها اليمن ولم يستطيع الناس الحصول عليها بسهولة نظرا لارتفاع أسعارهها ألا وهي "الكمامات".

هناك العديد من طرق الوقاية والتي يوصي بها كل الجهات المعنية لكن لبس الكمامات أيضا شئ أساسي للوقاية من الفايروس .

في هذا المقال سأجمع لكم بعصض الأفكار البسيطة في كيفية تصنيع كمامة لنفسك ومن أشياء بسيطة دون الإحتياج للاخرين.

1-في هذا القسم يتم تصنيع الكمامة عن طريق تشكيلها برسم تقريبي لكمامة سابقة ومن ثم قطع نفس الأشكال من أحد الملابس المتواجدة في البيت ليتم ربطها معا والخروج بكمامة جاهزة للإستخدام بحيث إمكاننا إستخدامها لفترات طويلة عن طريق غسلها ,وكل الطرق المتبعة لتصنيعها مرفقة لكم في الفيديو التالي.

Arduino Microcontroller basics

Arduino microcontroller is the skeleton for those who want to start digging into robotics and small mechatronics systems. Arduino is such an open-source for anybody who wants to engage , develop, or even work with their applications or existing projects. It has its own kit so that if you are a beginner you have to rake the chip with its all kits because it's a practical topic nomore.With arduino we can develop our business , improve ourselves in technology side, and know what is going on in anything surrounding us . We can integrate the systems together ,CAD programs with CAM programs.We can draw our project elements with Solidwork program ,then implement its controlling by just using Arduino microcontroller.

Servo systems application

Servo motor has lots of application in our life.It can be used lots industrial ,and medical applications .In this video we tried to explain that how to control the direction of servo motor by using potentiometer so that we can rotate the shaft of the motor by the amount of rotation which we want .Normally,servo motors have some constraint in rotation amount .Some of them may rotate 180 degrees the other may rotate 360 .As an example ,we in controlling cars vehicles direction .smoothly we can replace the classical systems that they are follow by attaching a four bar mechanism to front wheels to be connected with one degrees of freedom servo motor attached to one joint ,and the potentiometer will be attached to the wheel driver where we can rotate the system lightly ,with small energy and high efficiency.In addition to that ,servo motor can be used in surveillance cameras that we are seeing everyday,also in automatic gate that placed in front of our houses.

The importance of 3D Printings

3D printing is one of the most interesting topics that everybody aims to learn in order to grow up his/her business. It can be used in different types of applications. It is really important to know the basics of this technology because all over the world they are familiar with it .You can use it in home ,in your office,in your decoration .As an engineer in robotics area I am using this technology everyday in order to build up my robot arms ,form my machine mechanism,also create the complex shapes that I cannot form them by using simple manufacturing machines like CNC machines ,or any other kind of fabrication tools.

In medical application ,they are also using them in order to design pionic parts for those who missed them in any kind of life circumstances. In the decoration system too , they use these machines to manufacture a generate their beauty so that you can design your own gift easily ,and present to anyone who you like.

Finally, with 3D printings, we can do whatever we like.

Robot manipulators design-2

 

Robot manipulators are used in the most of the automated systems nowadays n this post, we brief some explanations in the fundamentals that robotic engineer needs them in order to design a robot manipulator which are 1-To know the task that the robot will do it later 2- To know the exact and specified workspace where, and how the robot manipulator will work 3-to decide the construction of the robot manipulator according to the payload that the end effector will elevate later on so that we can select the material types, and also decide elements shape and dimensions too. Robot arms have lots of benefits in our life application so that they can eliminate time-wasting for manufactures softly, relatively quick in returning money to the investors, free human workers from risk, hazardous and dull, eliminate errors, and they can work 24/7 with Non-stop working. Robot arm elements are strictly similar to the human arm so it has a base, shoulder, elbow, wrist, and end effector. In comparing to a human being arm the base is the body of a human and the hand is represented with end effector so they perform the same target in all conditions. As a starting point, we chose a workspace, to begin with. The workspace can be defined as the place where the robot arm can reach from different orientations. There are two methods to specify, study, and analysis workspace of the robot manipulator which are the graphical method, and analytical method. In the graphical method, we can draw the robot mechanism with CAD program so that the workspace will be specified from the generated shape. However, in the analytical method, we can derive formulations of the workspace by analyzing the understandable geometrical shapes and using some algebraic theorems. Finally, we can verify our workspace analysis by comparing both methods so that if they are similar to each other, we can be sure that our analysis is correct and we can go further in our next steps that I will explain in the coming videos.
