AutoHotkey

When you want to automate an action, just right click on the icon at the bottom right next to the clock and click on Record or the record button on the main interface. For example, let’s say you want to open the internet directly on your favorite site, without changing the default homepage. Close all windows, press the register button from the WinParrot icon at the bottom, give a name to the .wpr file that stores the actions and then start opening the internet browser, click the address bar and write the address you want.

A non-rigid or deformable body may be thought of as a collection of many minute particles (infinite number of DOFs), this is often approximated by a finite DOF system. When motion involving large displacements is the main objective of study (e.g. for analyzing the motion of satellites), a deformable body may be approximated as a rigid body (or even a particle) in order to simplify the analysis.

A system with several bodies would have a combined DOF that is the sum of the DOFs of the bodies, less the internal constraints they may have on relative motion. A mechanism or linkage containing a number of connected rigid bodies may have more than the degrees of freedom for a single rigid body. Here the term degrees of freedom is used to describe the number of parameters needed to specify the spatial pose of a linkage. It is also defined in context of the configuration space, task space and workspace of a robot.

An example of a simple open chain is a serial robot manipulator. These robotic systems are constructed from a series of links connected by six one degree-of-freedom revolute or prismatic joints, so the system has six degrees of freedom.

Click on Create New Macro to access the window, from which you can start recording the macro. Click RECORD and start moving the mouse, opening programs, typing texts and so on. The software will record every single movement and action and when you finish recording click CTRL + SPACEBAR to finish. All recorded actions will be displayed on the program screen (as seen from the figure below).

At any time you can start recording (clicking on REC button), stop recording (even using the key ESC) and then save the macro on your PC. The recorded macro can be imported into the program and played back at any time. You can define the number of repetitions and/or schedule the macro to start at a certain time and day (for example at night).

The mobility formula counts the number of parameters that define the configuration of a set of rigid bodies that are constrained by joints connecting these bodies.[3][4]

There are two important special cases: (i) a simple open chain, and (ii) a simple closed chain. A single open chain consists of n moving links connected end to end by n joints, with one end connected to a ground link. Thus, in this case N = j + 1 and the mobility of the chain is

MouseKey Recorder is the first software on the list because it represents one of the simplest and most practical solutions to record a “macro”. A macro is basically a set of procedures that are recorded and then reproduced automatically.

In electrical engineering degrees of freedom is often used to describe the number of directions in which a phased array antenna can form either beams or nulls. It is equal to one less than the number of elements contained in the array, as one element is used as a reference against which either constructive or destructive interference may be applied using each of the remaining antenna elements. Radar practice and communication link practice, with beam steering being more prevalent for radar applications and null steering being more prevalent for interference suppression in communication links.

If you have to do a task that is identical every time, you can use the free program called WinParrot to repeat actions (mouse and keyboard) in a really simple way.

The position of an n-dimensional rigid body is defined by the rigid transformation, [T] = [A, d], where d is an n-dimensional translation and A is an n × n rotation matrix, which has n translational degrees of freedom and n(n − 1)/2 rotational degrees of freedom. The number of rotational degrees of freedom comes from the dimension of the rotation group SO(n).

In physics, the degrees of freedom (DOF) of a mechanical system is the number of independent parameters that define its configuration or state. It is important in the analysis of systems of bodies in mechanical engineering, structural engineering, aerospace engineering, robotics, and other fields.

The position of a single railcar (engine) moving along a track has one degree of freedom because the position of the car is defined by the distance along the track. A train of rigid cars connected by hinges to an engine still has only one degree of freedom because the positions of the cars behind the engine are constrained by the shape of the track.

With MouseKey Recorder it is possible to record any repetitive activity done on the computer and then reproduced (even infinte times) when and how you want. It is really simple to use and there are no complex configurations to do.

An automobile with highly stiff suspension can be considered to be a rigid body traveling on a plane (a flat, two-dimensional space). This body has three independent degrees of freedom consisting of two components of translation and one angle of rotation. Skidding or drifting is a good example of an automobile's three independent degrees of freedom.

The best way to handle repetitive tasks is to record the movements and clicks of the mouse and then also the keys on the keyboard and the key combinations. The free program Ghost Mouse records the operations carried out on the computer and allows them to be repeated automatically

For example, the trajectory of an airplane in flight has three degrees of freedom and its attitude along the trajectory has three degrees of freedom, for a total of six degrees of freedom.

Physical constraints may limit the number of degrees of freedom of a single rigid body.  For example, a block sliding around on a flat table has 3 DOF 2T1R consisting of two translations 2T and 1 rotation 1R.  An XYZ positioning robot like SCARA has 3 DOF 3T lower mobility.

The degree of freedom of a system can be viewed as the minimum number of coordinates required to specify a configuration. Applying this definition, we have:

There are two versions of the program: BASIC version and ADVANCED version (the latter offers the possibility of modifying and customizing the macro thanks to an integrated editor). You can download the free trial version from the official website: https://mousekeyrecorder.net/download/

Macro recorder software can be handy for various tasks such as automating data entry, repetitive formatting tasks in documents or spreadsheets, testing software applications, or any other task where you find yourself doing the same steps over and over again. It can save a significant amount of time and effort for users who regularly perform such tasks.

It is common practice to design the linkage system so that the movement of all of the bodies are constrained to lie on parallel planes, to form what is known as a planar linkage. It is also possible to construct the linkage system so that all of the bodies move on concentric spheres, forming a spherical linkage. In both cases, the degrees of freedom of the links in each system is now three rather than six, and the constraints imposed by joints are now c = 3 − f.

A specific type of linkage is the open kinematic chain, where a set of rigid links are connected at joints; a joint may provide one DOF (hinge/sliding), or two (cylindrical). Such chains occur commonly in robotics, biomechanics, and for satellites and other space structures. A human arm is considered to have seven DOFs. A shoulder gives pitch, yaw, and roll, an elbow allows for pitch, and a wrist allows for pitch, yaw and roll. Only 3 of those movements would be necessary to move the hand to any point in space, but people would lack the ability to grasp things from different angles or directions. A robot (or object) that has mechanisms to control all 6 physical DOF is said to be holonomic. An object with fewer controllable DOFs than total DOFs is said to be non-holonomic, and an object with more controllable DOFs than total DOFs (such as the human arm) is said to be redundant. Although keep in mind that it is not redundant in the human arm because the two DOFs; wrist and shoulder, that represent the same movement; roll, supply each other since they can't do a full 360. The degree of freedom are like different movements that can be made.

For a simple closed chain, n moving links are connected end-to-end by n + 1 joints such that the two ends are connected to the ground link forming a loop. In this case, we have N = j and the mobility of the chain is

Whenever repetitive actions has to be done, it can be replicated perfectly after recording. If you want to record keyboard only or mouse movement or clicks only, go to the options menu and choose what to record.

This tool can be used to repeat mouse clicks or double clicks at a point on the screen. You can use it to keep a window always on top or for other tasks.

MouseController is an open-source desktop application for Windows 10/8, Windows 7 and XP that allows you to record mouse movements and clicks, and then automatically repeat them in sequence, at any time.

Instead, abount the BASIC version, after downloading and installing it on your PC, a screen will open just like the figure below.

If you need to click the same button every minute or if you have to copy and paste, if you always have to send the same reply at predefined intervals, and for other things that can cause carpal tunnel in the wrist paralyzing the hand, you can use the program Free Mouse Auto Clicker.

A summary of formulas and methods for computing the degrees-of-freedom in mechanical systems has been given by Pennestri, Cavacece, and Vita.[5]

An example of a simple closed chain is the RSSR spatial four-bar linkage. The sum of the freedom of these joints is eight, so the mobility of the linkage is two, where one of the degrees of freedom is the rotation of the coupler around the line joining the two S joints.

By clicking Play Macro button you can play the recording and the computer will work automatically! Finally, there is also a very important Scheduler section to be able to program the automatic start of the macro.

A macro recorder software is a tool that allows users to record their actions on a computer and then play them back later. It’s particularly useful for automating repetitive tasks or sequences of actions.

In mobile robotics, a car-like robot can reach any position and orientation in 2-D space, so it needs 3 DOFs to describe its pose, but at any point, you can move it only by a forward motion and a steering angle. So it has two control DOFs and three representational DOFs; i.e. it is non-holonomic. A fixed-wing aircraft, with 3–4 control DOFs (forward motion, roll, pitch, and to a limited extent, yaw) in a 3-D space, is also non-holonomic, as it cannot move directly up/down or left/right.

Consider a system of n rigid bodies moving in space has 6n degrees of freedom measured relative to a fixed frame. In order to count the degrees of freedom of this system, include the fixed body in the count of bodies, so that mobility is independent of the choice of the body that forms the fixed frame. Then the degree-of-freedom of the unconstrained system of N = n + 1 is

By clicking on each action you can modify or remove it. You can also add actions by clicking on the top bar. In short, the macro is 100% customizable to fully satisfy your needs.

Joints that connect bodies in this system remove degrees of freedom and reduce mobility. Specifically, hinges and sliders each impose five constraints and therefore remove five degrees of freedom. It is convenient to define the number of constraints c that a joint imposes in terms of the joint's freedom f, where c = 6 − f. In the case of a hinge or slider, which are one degree of freedom joints, have f = 1 and therefore c = 6 − 1 = 5.

For example, you can use it to move the mouse automatically after a certain amount of time to prevent the computer from going into standby or to repeat the same action multiple times. The application is quite powerful and easy to use, moreover, it is a portable program that does not require installation.

The exact constraint mechanical design method manages the degrees of freedom to neither underconstrain nor overconstrain a device.[1]

A single rigid body has at most six degrees of freedom (6 DOF) 3T3R consisting of three translations 3T and three rotations 3R.

Once downloaded, the interface is only two buttons: Record and Playback. The red button allows you to record mouse and keyboard actions. At the end you have to press Stop and save the automation (from the File menu) to play it whenever you want.

At the top right there are other parameters that allow you to set the repetitions (number of times the macro must be executed), the speed and the action to be performed at the end (e.g. turning off the PC).

The position and orientation of a rigid body in space is defined by three components of translation and three components of rotation, which means that it has six degrees of freedom.

An example of a planar simple closed chain is the planar four-bar linkage, which is a four-bar loop with four one degree-of-freedom joints and therefore has mobility M = 1.

The result is that the mobility of a system formed from n moving links and j joints each with freedom fi, i = 1, ..., j, is given by
