Linear Actuators and Motion Systems - Start Working with Raspberry Pi

The world of technology has improved a lot and therefore, this has resulted to development of systems that help in the teaching of computer science to ensure that students keep up with the current technological changes. Among these system is the Raspberry Pi which provide learners with basic programming knowledge such as the controlling of a 12V linear actuators. Motion systems are designed to create motion to an appliance by creating a rotary motion. As a result, the appliance is able to move in a circular motion. On the other hand, linear actuators produce linear motion which enables the item to move in a straight line.


The basic information in the usage of a Raspberry Pi is learning the appropriate language such as python to use in controlling of the actuators. The raspberry Pi has more that seventeen GPIOs which can be connected to the actuators that one needs to use hence making it for the user to even control more than one actuator. Computer science learners have the obligation of determining the amount of python language that they need to know before starting the program in order to make work easier for them.


The GPIOs pins enables the programmer to control the amount of voltage that can be allocated to the actuator hence making it possible to carry out physical computing. As a result, this enables the programmer to communicate to the actuators. In return, the programmer can read the voltage of the actuator and this gives an insight of how the actuator communicates with the programmer. Therefore, this will aid in controlling the motion of the actuator. Each of the pins of the Raspberry Pi is a representation of a binary state and, therefore, the programmer can only input a 1 or a 0. One of the common actuators that learners can use is the 12V linear actuator.


In addition, through the use of the Raspberry Pi, an individual is able to convert rotary motion produced by motion systems into a linear motion using a processor. However, the Raspberry Pi cannot function on its own and would need some external power supply in order to complete the system. A good example of Raspberry Pi usage is the creation of surveillance motion cameras which makes it easy for the individual to monitor them using the local internet connection. Such surveillance cameras are easy to make since they only require the basic programming language of python.

There are plenty of actuators in the market and, therefore, their choice depends on speed, stroke, voltage and the force that they produce. In terms of voltage, most actuators require twelve or twenty-four volts in order to function well during automation.  Given that different projects require unique types of actuators, then an individual has to consider more characteristics of the actuator such as the limit switches, IP ratings, and mounting options among others. The strokes show the length that the device can move while the speed indicates how fast it can move depending on the amount of voltage applied. As well the force indicates the specific weight that the actuator can withstand. Therefore, for an individual to ensure the success of a project that involves the use of a Raspberry Pi, it is important for them to familiarize with the python programming language and the different types and characteristics of actuators.
