GPS電動插秧 農夫靠邊站

XDDD
難道自動農場的日子不遠了??
人只要負責Load物件 SellOut就夠了??

不過這也得要大型財團才玩得起吧
只是說 控制也能弄到如此 真的是很好玩的事情!!
(雖然裡面的東西 絕對不簡單.....  )
[The Grant Challenge是要速度  這個是要經準度!]

太誇張了！

可是，如果雲層過厚，會不會把秧苗種到路上？

其實價格還好, 台幣兩百多萬買個農具, 以日本或美國農家來說, 應該都還在可接受的範圍之內......

當然對台灣農家來說是有點太貴了啦......

GPS訊號不穩時機器會停下來

An automated rice transplanting system has been developed. This study’s objective
was to develop an automated operation system to make precise operation more efficient. A real-time kinematic GPS (RTKGPS) was used to locate the position and fiber optic gyro(FOG) sensors to measure the direction and the inclination of the vehicle. RTKGPS has 2-cm precision at 10-Hz data output, but the vehicle inclination influences the position data and the position data has about 70-ms delay. The influence of the vehicle inclination is corrected by measuring the inclination with FOG sensors. The RTKGPS receiver generates one pulse per second as cues for measuring the position. A timer was used to synchronize measuring the position with the inclination every 100 ms. When the vehicle was driven straight automatically, the deviation from the desired straight path was less than 10 cm. The GPS data quality indicator was obtained during the operation, and the operation was interrupted when GPS could not locate the precise position.

連這種東西都有啊~真是太神奇啦

誤差在兩公分內??這是用軍事衛星定位的嗎??

傑克這真是太神奇了:o

內文有提到同時運用五顆衛星校正，所以能夠到達誤差在兩公分內。

應該是有另外架地面發射站校正才有這種精準度。

真是太神奇了, 居然有人會這麼聰明.

理論上衛星定位只要三顆衛星就可以定位了，如果訊號正確的話。
衛星數目愈多不見得可以縮小誤差，如果訊號不穩反而容易飄移。

要達到兩公分的精確度，如果不用軍規，那就非得架參考台不可了
