上海的RoboPeak
非常高兴上海 RoboPeak 机器人研发团队会在 3／26的活动 上为我们带来演说。非常期待。
从他们的网站上：
RoboPeak是国内由一群软件工程师、电子工程师、新媒体艺术家所组成的机器人及相关技术领域的设计研发团队，团队于2009年底创建。 团队致力于民用机器人平台系统、机器人操作系统(ROS)以及相关设备的设计研发，并尝试将日新月异的机器人技术融入人们的日常生活与娱乐当中。同时，我们将尽力为机器人技术在开源硬件、开源软件社区的普及做出贡献。 团队在嵌入式系统、系统级软件/固件、图像识别等领域拥有丰富的经验，拥有独立设计，开发机器人操作系统、相关传感器设备硬件/固件的能力。
这个团队在机器人和Arduino上做了相当多开发，详细的情况可以查看他们的博客.底下的图片来自他们的博客，看起来相当有趣的机器人设计，期待周六和他们见面。

Hackerspace in Shanghai: Our Maker Neighbors
March 19th, 2011 § 0 comments § permalink
XinCheJian’s Neighborhood
I have recently been asked quite a lot of questions about hackerspace, hacker culture and impact of hackerspace in China. This has gotten me starting to think a lot about what it means to run a hackerspace. I decided to take a walk around the neighborhood and find anything that’s related to makers. The following pictures are shops with in 500 meters of our new location in Anhua Lu. It’s a typical Shanghai neighborhood and quite interestingly how many maker related shops are around us.
Welding on the street
Bike modding? The guy is attaching a new rack to the back of the bike to carry more goods.
Window Frame Maker
They got good collection of aluminum windows frame and can cut it to any size we want.
Glass shop
Cotton Shop
This is a surprise fouind.
Lock Smith
Hardware Store
Quite a collection of home improvement materials
Home Appliance Repair
Also sell used home appliances. Will for treasure hunt one of these days.
Quadcopter Frame ready!

We have the FRAME!!!
Danny show up in Barcamp with a big surprise! He show me the fiber/aluminium frame of the quadcopter he just got CNCed. What a beauty!
Beauty and Makerbot

I shoot this a while back to promote Hackerspace but never get around to publish it. Strobist is the tinker of light and the hacker among photographers.
Some strobist setup info here:
- SB-600 inside the makerbot - SB-800 on shoot-through umbrella to the camera right

新车间搬家了哦！
经过在 新单位二楼三个月的孵化后，新车间成长了，要飞了。在安化路和江苏路的老工厂里面找到了一个100平米的新场地，新车间现在真的在工厂里面了。应该在三月底就会装修好。欢迎大家来玩。
Lovely neighborhoold
There are all kind of business around. I am sure we can use them in our making.
Yes, it’s a real factory (che jian)!
Let the be light
One big side of the room is full of window.
Plenty of space

XinCheJian, Hackerspace, Robots, and HCR at Barcamp Shanghai
March 13th, 2011 § 1 comment § permalink
XinCheJian was in Barcamp Shanghai!
We took the Green for the afternoon to talk about Hackerspace, Maker, Open Source Hardware and of course ROBOTS!!! 😉
The crazy robot car David was carrying around at Barcamp
The robot was built the night before barcamp with YM4 from Embedream, Arduino Uno and a HC-SR04. The little YM4 is a lot of fun. The independently controlled wheels allowing the car to turn on a fix axis and this saves the use to savor to turn the limited angle SR04 around to inspect the environment. But at 3AM, it was discovered a little drawback of controlling two independent wheels while trying to make the it going straight. Well, it was 3AM so I decide to let it acts a little crazy. I am dedicating this crazy robot to the crazy Shanghai taxi driver who took me to the barcamp in the morning! I will name it 840. 😉
Pitching Hackerspace
Kicking off the afternoon with pitch of Hackerspace and Maker Culture
Hmm, this is why the call this session “THE GREEN.” Get to make fun of making is much more fun then golf as hobby.
HCR, the open source robots from DFRobot
Rick Ye gave a talk on his open source HCR robot. I was driving it around to round up people to the talk. This version has a cam pointing upward and a automated navigation mode. It’s a lot of fun to watch it walking all over the place on its own from the video at the control.
This little guy has great potential to be a good caddy on the green.
Video of HCR
Thanks to Scott for the video.

March 5th, 2011 § 0 comments § permalink
#ym4-arduino-uno img { margin:5px; padding:5px; display:block; }
Another weekend night of hacking fun hooking up a Arduino Uno with YM4 robotic car from EmbeDream. The YM4 is a well designed FIRA compliant robot car with built in power supply. The left and right wheels are controlled independently and the built in feedback from wheels.
The break out board for the YM4 is easy to work with. The H-bridge control are CT1, CT2, and CT3. CT1 control the speed with PWM and CT2/CT3 decide the direction of the wheel. This is the same configuration for both wheels. The following is a quick sketch to get YM4 going forward.
#define RIGHT_CTRL_1 5
#define RIGHT_CTRL_2 6
#define RIGHT_CTRL_3 7
#define LEFT_CTRL_1 11
#define LEFT_CTRL_2 12
#define LEFT_CTRL_3 13
void setup()
{
pinMode(RIGHT_CTRL_2, OUTPUT);
pinMode(RIGHT_CTRL_3, OUTPUT);
pinMode(LEFT_CTRL_2, OUTPUT);
pinMode(LEFT_CTRL_3, OUTPUT);
}
void loop()
{
digitalWrite(RIGHT_CTRL_2, 0);
digitalWrite(RIGHT_CTRL_3, 1);
analogWrite(RIGHT_CTRL_1, 128);
digitalWrite(LEFT_CTRL_2, 0);
digitalWrite(LEFT_CTRL_3, 1);
analogWrite(LEFT_CTRL_1, 128);
}
Now, the TODO list
- Find a more secure way to protect the Uno board and protect it from bumping into objects when robot start to run
- Figure out how and where to attach sensors: ultrasonic distance and infra red for distance and obstacle sensing
