My motto is: Contended with little, yet wishing for more.

我的座右铭是:为一点点感到满足,但希望获得更多。

If you can live your life in this way, you will feel much happier about your life and you will always be optimistic about your future.

Actually, most of our unpleasant memories and depressing experience stem from our endless lust and unmatching efforts.

Be dynamic and energetic, with vigorous drive from internal and outernal, there is no difficulty that we can‘t overcome.

 

If a writer wrote merely for his time, I would have to break my pen and throw it away.

如果一位作家只为自己所处的时代而写作,那我只得把自己的笔掰断了再扔掉。

From Victor Hugo.

If you can depict your time vividly with your pen, you will surely be considered as a great writer.

I wish I can be a great coder whose program can work well on those machines. 

And it would be much better if I can contribute a little to the open-source community at the same time.

 

Today I wish I can finish the goal of setting up the ros environments for my RaspberryPi-3B with the Raspbian operating system.

There are two ways provided by the ROS to install ros-kinetic on Raspberry.

One is using Ubuntu-Mate/16.04 Xenial of armhf, and we can install the ros-kinetic in the same way as on our pc, it is easier and faster.

The other is to install the ros from the source, it assumes that Raspbian is being used as the operating system on the Raspberry-Pi.

Currently, the two most used ros versions are ros-kinetic and ros-indigo, corresponding to ubuntu 16.04 xenial and ubuntu 14.04 trusty, for the Raspbian, they are Raspbian-Stretch and Raspbin-Jessie.

We should combine the two tutorials together to complete the installation of ros-kinetic on raspbian-stretch, otherwise it won‘t work.

The links about how to install ros on Raspberry-Pi are as follows:

ROSberryPi

Installing ROS Kinetic on the Raspberry Pi

Installing ROS Indigo on the Raspberry PI

Enjoy the process of installation and try to build up your own auto-driving sytem based on ros.
