Technology is something which has come forward in leaps and bounds over recent years, and it is something which Progressive Automations in particular has taken advantage of. Technological advancements have meant that various computer systems which can be used in the teaching of computer sciences have progressed sharply; if they had not, of course, students would leave their classes unable to handle the more up-to-date versions of computer programs which had come out during the time they had been learning.
One such system which has been developed to help in teaching is Raspberry Pi, a system which brings raspberry pi and actuators together to allow students to become proficient in handling linear actuators and the motion systems they are often attached to.
The basic handling of a linear actuator with a Raspberry Pi control system is something which comes down to learning the operating language (usually Python, or a similar language). The language then gives the controller a stronger ability to communicate with the motion system which they are controlling. Raspberry Pi itself has over seventeen GPIOs attached to it, meaning that the operator at any given time can control a group of more than one actuator. When it comes to computing and programming classes, learning the languages (such as Python) before anybody comes into contact with the systems which require it is a good way of ensuring that they will have all the knowledge they need before they need it.
People who have learned the appropriate languages for use with the system will be able to control their linear actuator(s) with Raspberry Pi if they ever need to. Using the system, they will then be able to convert the rotational motion of a common motor into linear motion for various tasks, including security systems and baby monitors, if they are needed to move. The main problem people have with the Raspberry Pi system is that it does not have its own power source; an external power supply is needed for Raspberry Pi, and therefore any attached linear actuators – to function. This naturally requires the Raspberry Pi system to be connected up in some fashion, and therefore limits what a linear actuator can do, as it needs to be connected to the power source.
The market has produced many different types of linear actuator, and will continue to produce more as they become more integral to our current technology; there are, therefore, plenty of ways in which they can vary according to stroke length, speed, and accuracy. These are all things which anybody who is using a Raspberry Pi control actuator needs to be aware of, so that they can then make the necessary changes for accurate control of their equipment.
In addition to that, smaller details such as the IP rating (the ratings which tell people who are using an actuator whether it will withstand adverse conditions – i.e. dusty or wet ones), the stroke length (and whether or not a limit switch will be required for the work which requires the actuator in the first place), and the weight which the actuator can take. Anybody who is aiming to use Raspberry Pi for controlling linear actuators should therefore aim to familiarise themselves with the Python programming which is involved with each of those areas, to ensure that they know what to do.
