New Raspberry Pis and Cases

I received 2Raspberry Pis and 3 cases.
I had been waited for 20 weeks.
But....
2 Rapis I received are "Made in China".
Why?
Not UK 　　?(>_<)?
I think Rs is not very precise.

peace!

The Video !! Walking a 4 legged robot. v(^.^)v

Please see a  prototype robot video.
It's a powerful  4 legged robot.

This prototype robot is used for functional verification.
It seem a simple robot, but it have many function.
Space recognition, obstacle detection,  autonomous locomotion,,,,

These function is  on my original robot platform called 'RDCS'.
I will improve these robot function  using  results of prototype robot testing.

By the way, he recognizes  his environment through his eye (xtion).

Peace!

Now status:4 legged robot. New robot bench.

I'm developing a motion realtime generation program for my 4 legged robot.
It's very difficult program for me.  I'd like to develop the program in this week.
I made a robot bench.  When I debug a motion realtime  generation program, i use this bench. It took 4 hours to make this bench.
Now I develop a prototype 4 legged robot. This bench is able to use too, when  i will develop a next robot which work in my farm and greenhouse.

A new face

I've developed a forward  obstacle detection system of my prototype robot.
When there are obstacles that can not be over in the range of 30cm front, my robot avoid the obstacles.

ロボットの前面に、障害回避の機能を設置しました。
ロボットの前、３０ｃｍ程度に存在する、乗り越えられない障害物を回避します。


Agricultural robot will be operated  in outdoor such as 'farm' and  'greenhouse'. Therefore, it is more complex than the robot to work indoors. It require dustproof, waterproof,,,. However, the production cost is $ 2,000. It is a very difficult challenge.
I developed a 1/2 scale prototype robot , and  I'm testing the robot function.
There are many improvements and issues.  (~.~), foo
I have to resolve and advance step by step.

農業ロボットは、農場やハウスなどの野外で運用されます。室内で活動するロボットより複雑です。
例えば、防塵、防滴などが必要になります。それも、2000ドルで開発しなければなりません。難しい挑戦です。1/2スケールの試作機を作りながら、プログラムなどの最終チェックをしています。

I didn't describe how to recognize tomatoes, because it's a new method.
I will explain, when  the test of  recognizing tomatoes will finish.

トマトの認識技術については、これまで書きませんでした。
従来のように、画像処理を中心にした認識技術では有りません。テストが終わった時に説明します。

peace!

Nexus 7 broken! (-.-)...

Today Suddenly,  Nexus 7 don't boot.
Google service said "It's initial failure."
Over one week, I can't develop a image processing software on Nexus 7.
It's shocked.

A new robot on 4 legs. (prototype)

Now, I'm developing a 4 legs robot. The pictures are a prototype 4 legs robot.
The prototype robot is half size model.
４本脚ロボットを開発しています。写真は、そのプロトタイプです。

30cm ruler in lower side

I grow organic tomatoes in the greenhouse.  And in the greenhouse, an aisle is narrow (40cm) and uneven ground.

 There are several robot moving methods  that are wheels, caterpillar, 4 legs and others. I have considered  which is the best moving method in the 'farm' and 'greenhouse'.
I decided to develop a 4 legs robot, first of all.

私は、化学農薬などを使わないオーガニック　トマトを農業ハウスで栽培しています。
ハウス内は、通路も狭く、また平ではありません。

ロボットの移動方法には、車輪、キャタピラー、４本脚、それ以外の方法もあります。
最初に、４本脚のロボットを作る事に決めました。


The selection points are below:
(1) A function of holding on the level ( a height level requirement )
My forming robot have to move on the application which are an actuator, pruner machine,,,
Therefore a robot need to hold these applications on the level in order to exercise their capacities.
A wheel and caterpillar machin are difficult to hold on the level.
But 4 legs moving system is easy to realize  my height level requirement, nothing any other parts.
I'm going to research and to develop for putting into practical use.


peace!
