If the reply can be made with using just one ‘and’, then Arduino can fit the bill easily. Ask yourself what you want your project to do. You can simply follow this rule of thumb to make a decision faster and more easily. The Raspberry Pi, being a full-fledged mini-computer with slots to support external devices, is quite useful in multi-media projects and can be of great use in making small, multi-functional gadgets. You may require the RPi if you need to do encryption programs, which are difficult as well as complicated. Raspberry Pi projects are more complicated than the activities mentioned above. If you prefer to have large community support, have less time and want something to support your project that does not have as many functions, it is advisable to pick Arduino. The Raspberry Pi models may not be required for such simple projects, which can easily be completed with an Arduino board. Another important project is to record temperature on a daily basis and flash it on any social media network. For example, this project using robots for picking a material and keeping on processing platform is a simple act but requires the task to be done repetitively. When you want your robot to do simple but repetitive tasks, you can consider using Arduino. The user may find it a bit more complicated to use than Arduino.īoth of these have their own utility bases and are considered for use after analyzing the requirements of a robotics project and its outcome. It comes with the Linux operating system and is multi-functional in nature because it supports running multiple programs simultaneously. On the other hand, a RPi is a miniature computer for general purposes. It is very easy to use and does not demand much in terms of in-depth knowledge about microelectronics. Image: Digi-KeyĪn Arduino can be better understood as a microcontroller motherboard having limited ability to run one program in a single instance repeatedly. Thus, before we pass a verdict on whether Arduino or Raspberry Pi is better for a particular robotics project, we must first understand the basic differences between the two platforms.Ĭomparing the Arduino and Raspberry Pi Platforms The Arduino (left) and Rapsberry Pi (right) are both low-cost, open-source computing platforms but they are optimized for very different types of applications. Whether the running of various programs simultaneously is required or not is also dependent on the number of tasks that we expect the robot to do. Robotics projects require using certain resources that support running multiple programs at once. In order to make a good choice about which one is better for your robotics project, you first must understand the basic differences between the two. The scope of your project is too open for clear answers.The classic Arduino platform and the newer Raspberry Pi architecture each have their own unique strengths, capabilities and weaknesses. If you provide more information about the concrete target capabilities you might get a better answer. Depending in your needs you can either use only this microcontroller to do all the other things too or connect another board as a master (eg over I2C vor SPI) which tells the microcontroller what to do. Since you also want wireless control you might be interested in using an ESP (WLAN) as a microcontroller.Īll in all you should use a microcontroller for driving the balancing logic and motor control. For these real time fast applications a simple microcontroller is fitted better. Programs in it don't have a garanteed time of execution, so especially under high load the program might have to wait for its turn, effectively destabilizing the robot. A RaspberryPi is in principle a computer, not a microcontroller. There is also another side to the problem: A self balancing robot needs to control its motors very fast (changing the direction fastly depending in sensor input). The RaspberryPi has of course big display capabilities (like 1080p over HDMI). Using a more capable Arduino (like the Mega) can extent the capabilities of your project. Better are little screens (like small OLED screens or small LCD displays with integrated controller). An Arduino UNO can with big effort interface a VGA signal with very low resolution and only few colors. This depends on the type of screen you want to interface.
