从事 IT 的经常要做一些 IT 实验,直接在宿主机上操作风险比较大,所以一般建个虚拟机,很多人喜欢安装 vmware workstation,其实 windows 10 以后就自带免费的虚拟软件,一些常见的快照功能(hyper-v叫检查点)和网络配置,hyper-v都有。而且相比 vmware workstation,有以下优势:

生活需要一些小巧实用的工具,它们能够在细节处为我们带来便捷。以下是八款简洁实用的工具,看看它们是否适合您的生活。

一、图片压缩工具 —— TinyPNG

TinyPNG是一款智能的图片压缩工具,可以减少WebP、PNG和JPEG图片的文件大小。通过有损压缩技术,TinyPNG可以选择性地减少图片中的颜色,从而减少存储数据所需的字节数。压缩效果几乎不影响图片质量,但可以显著减小文件大小。TinyPNG适用于压缩网站或应用中的图片,可以节省带宽和提升加载速度。

与倒立摆相似,单腿跳跃机器人是自然不稳定系统,在实际的规划与控制中,需要保证控制的实时性。这使得实时控制的研究显得至关重要。

Windows系统本身不是实时操作系统,但是,对于采用上/下位机模式(如PC+DSP)的控制系统,因为下位机的定时精度高且响应快,通过合理的设计,同样可以保证整个控制系统的实时性。

针对单腿跳跃机器人控制的要求,重点研究了实时控制技术,并给出具体控制方案。在联机调试之前,先设计实验验证该控制方案的可行。实验结果说明控制系统的实时性能满足设计要求。

1、 机器人控制系统的搭建

本文所研究的是一种新型弹性单腿机器人,该机器人采用双臂驱动,弹性伸缩腿中不安装驱动部件,系统依靠内部动力学耦合实现动态站立平衡、起跳和稳定连续跳跃。其机械本体如图1所示。

想象一下,如果你一次只能在你的计算机上运行一个软件会怎样。如果你想查看电子邮件,则必须关闭当前的程序。如果你想访问 Internet,则必须关闭 Word 文档或你当前正在使用的任何其他应用程序。看起来很有挑战性,对吧?

虽然我们认为一次运行大量应用程序的能力是“理所当然”,但我们很少考虑同时运行多个操作系统。值得庆幸的是,最佳虚拟机软件使在一台机器上并行使用多个操作系统变得更容易。尽管在一台物理机上运行两个或多个操作系统并不是一个新概念,但如果你是计算机新手,这里简要说明一下什么是虚拟机程序?

Windows7

The Intel Atom® E3800 Series Chipset (formerly codename: Bay Trail) was developed with the future in mind. Many of the legacy functions that have been routinely seen on most platforms, exist only on the E3800 chipset through means of emulation for items such as serial COM ports, whereas support of items like PS/2 mouse and keyboard interfaces are non-existent. Intel opted for the more versatile and popular USB interfaces. However, even USB is implemented with the future in mind, making the XHCI protocol (necessary for USB 3.0) the de facto protocol for USB operation. This creates difficulty for operating systems that were designed with legacy interfaces as the primary selections, such as Microsoft Windows 7.

While Microsoft Windows 8 / 8.1 installs on the E3800 platform without difficulty, Windows 7 is not as user friendly. With the default USB protocol of the E3800 chipset being XHCI, and the default USB pro- tocol of Windows 7 being EHCI, an incompatibility is created at the outset. Windows 7 does not support the XHCI USB protocol within its installer / bootloader. XHCI isn’t available in the Windows 7 operating system without the addition of the Intel USB 3.0 eXtensible host controller driver, after the base installa- tion of the Windows 7 operating system and chipset updates are installed. The following instructions are needed to guide the user through the process of installing Windows 7, as the standard method does not allow usage of USB input devices during Windows 7 install process.
