_This is the first in a series of two posts by guest blogger; Dominik Nowak, CEO at Husarion._
|

We’ve seen many breakthroughs happening in the IT industry over the last decade. Arguably the most meaningful one on the consumer side was the adoption of smartphones and mobile development. What’s the next big thing, now that the smartphones are so common and, let’s face it, slightly boring? We say: robotics.
|
||||
|
||||
Business knows that well with many manufacturing lines running solely by robots. The consumer and service side, though, have yet to see a massive breakthrough. We believe it’s all a matter of accessibility and lowering the barrier to entry for developers. There just have to be good, simple tools to quickly prototype and develop robots. To test new ideas and empower engineers, so they can solve many of the issues humanity still faces. Issues that are trickier to tackle than a tap in an app.
|
||||
|
||||
Building robots is a challenging task that the [Husarion][2] team is trying to make easier. Husarion is a robotic company working on rapid development platform for robots. The products of the company are CORE2 robotic controller and the cloud platform to manage all CORE2 based robots. CORE2 is the second generation of Husarion’s robotics controller and it’s now available [here][3].
|
||||
|
||||
CORE2 combines a real-time microcontroller board and a single board computer running Ubuntu. Ubuntu is the most popular Linux distribution not only for [desktops][4], but also for embedded hardware in IoT & [robotics][5] applications.
|
||||
|
||||
|
||||
|
||||
CORE2 controller comes in two configurations. The first one with ESP32 Wi-Fi module is dedicated for robotic applications that need low power consumption and real-time, secure remote control. The second one, called CORE2-ROS, basically integrates two boards in one:
|
||||
– A board with real-time microcontroller running firmware using the Real-Time Operating System (RTOS) and integrating interfaces for motors, encoders and sensors
|
||||
– A single board computer (SBC) running Linux with ROS packages ([Robot Operating System][6]) and other software tools.
|
||||
|
||||
The ‘real-time’ board does the low-level job. It contains the efficient STM32F4 series microcontroller which is great for driving motors, reading encoders, communicating with sensors and controlling the whole mechatronic or robotic system. In most applications, the CPU load does not exceed a few percents and the real-time operation is guaranteed by a dedicated programming framework based on RTOS. We also assured the compatibility with Arduino libraries. The majority of the tasks are processed in the microcontroller peripherals, such as timers, communication interfaces, ADCs etc. with the strong support of interrupts and DMA channels. In short, it is not a job for a single-board computer that has the other tasks.
|
||||
|
||||
On the other hand, it’s almost obvious that the modern and advanced robotic applications can no longer be based only on microcontrollers, for a few reasons:
|
||||
– Autonomous robots need a lot of processing power to perform navigation, image and sound recognition, moving in a swarm etc.,
|
||||
– Writing the advanced software requires standardisation to be efficient – SBCs become more and more popular in the industry and the same is observed for the software written for SBCs, which is very similar to PC computers
|
||||
– SBCs are getting less expensive every year
|
||||
– Husarion believes that combining these two worlds is very beneficial in robotics.
|
||||
|
||||
CORE2-ROS controller is available in two configurations with [Raspberry Pi 3 ][7]or [ASUS Tinker Board][8]. CORE-ROS is running Ubuntu, Husarion dev & management tools and ROS packets.

In the next post, find out why Husarion decided to use Ubuntu.

运行 Ubuntu 的 Husarion CORE2-ROS 使得机器人开发变得容易

_这是游客投稿的本系列两篇中的第一篇；Dominik Nowak，Husarion 的 CEO _
|
||||
|

过去十年，我们见证了 IT 行业的许多突破。可以说对消费者最有意义的一个方面是智能手机和移动开发的普及。接下来的大事件是什么，现在智能手机是如此常见，让我们面对它，有点无聊吗？我们猜是：机器人。
|
||||
|
||||
众所周知，许多生产线完全由机器人运行。但在消费者和服务方面，还没有看到巨大的突破。我们认为这是一个无障碍的问题，并降低开发人员进入的门槛。这只需要好的，简单的工具来快速做出原型和开发机器人。为了测试新的想法并赋予工程师权利，所以他们可以解决许多人类仍然面临的问题。比应用中的点按更棘手的问题。
|
||||
|
||||
构建机器人是一个具有挑战性的任务，[Husarion][2] 团队正在努力使其更容易。Husarion 是一家从事机器人快速开发平台的机器人公司。该公司的产品是 CORE2 机器人控制器和云平台，它用于管理所有基于 CORE2 的机器人。CORE2 是第二代 Husarion 机器人控制器，它可在[这里][3]看到。
|
||||
|
||||
CORE2 结合了实时微控制器板和运行 Ubuntu 的单板计算机。Ubuntu 是最受欢迎的 Linux 发行版，不仅适用于[桌面][4]，还适用于物联网和 [机器人][5]程序中的嵌入式硬件。
|
||||
|
||||
|
||||
|
||||
CORE2 控制器有两种配置。第一款采用 ESP32 Wi-Fi 模块的专用于需要低功耗和实时、安全遥控的机器人应用。第二个，称为 CORE2-ROS，基本来讲集成了两块板：
|
||||
- 使用实时操作系统（RTOS）的实时微控制器并集成电机、编码器和传感器接口的电路板
|
||||
- 带有 ROS（[Robot Operating System] [6]）包的运行 Linux 的单板计算机（SBC）和其他软件工具。
|
||||
|
||||
“实时”电路板做底层工作。它包含高效的 STM32F4 系列微控制器，非常适用于驱动电机、读码器、与传感器通信，并控制整个机电或机器人系统。在大多数应用中，CPU 负载不超过几个百分点，实时操作由基于 RTOS 的专用编程框架保证。我们还保证与 Arduino 库的兼容性。大多数任务都在微控制器外设中处理，如定时器、通信接口、ADC 等，它具有中断和 DMA 通道的强大支持。简而言之，对于具有其他任务的单板计算机来说，这不是一项任务。
|
||||
|
||||
另一方面，很显然，现代和先进的机器人程序不能仅仅基于微控制器，原因如下：
|
||||
- 自动机器人需要大量的处理能力来执行导航、图像和声音识别、移动等等，
|
||||
- 编写先进的软件需要标准化才能有效 - SBC 在行业中越来越受欢迎，而对于为 SBC 编写的软件也是如此，这与 PC 电脑非常相似
|
||||
- SBC 每年都变得越来越便宜
|
||||
– Husarion 认为，结合这两个世界在机器人技术方面是非常有益的。
|
||||
|
||||
CORE2-ROS 控制器有两种配置：[Raspberry Pi 3][7] 或 [ASUS Tinker Board][8]。CORE-ROS 运行于 Ubuntu、Husarion 开发和管理工具以及 ROS 软件包上。
