1．產生白噪聲程序 編程產生一組正態分布的白噪聲信號,它的均值和方差以及長度可隨意調整。將產生的白噪聲信號存入數據文件。 本程序算法用C++語言編寫。首先用乘同余法產生均勻分布白噪聲，再用變換抽樣法轉換為高斯分布白噪聲。算法及程序實現敘述如下。 1) 設定x初值為11,A＝179，長度WNlength,均值Average,方差Serror為用戶輸入的變量； 2) M =235，ζi= x/M； 3) 取ζi的小數部分再賦值給ζi＋1，這就是均勻分布白噪聲； 4) 利用公式 η1=Serror×(–2*logζ1)0.5×cos(2pζ2) ＋Average η2= Serror×(–2*logζ1)0.5×sin(2pζ2) +Average 計算得到均值和方差可任意調整的白噪聲序列。式中 為均勻分布白噪聲。

The Inter IC bus or I2C bus is a simple bidirectional two wire bus designed primarily for general control and data transfer communication between ICs. Some of the features of the I2C bus are: • Two signal lines, a serial data line (SDA) and a serial clock line (SCL), and ground are required. A 12V supply line (500mA max.) for powering the peripherals often may be present. • Each device connected to the bus is software addressable by a unique address and simple master/ slave relationships exist at all times masters can operate as master-transmitters or as master-receivers. • The I2C bus is a true multi-master bus including collision detection and arbitration to prevent data corruption if two or more masters simultaneously initiate data transfer systems. • Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 KBit/s in the standard mode or up to 400 KBit/s in the fast mode.

This paper presents a visual based localization mechanism for a legged robot. Our proposal, fundamented on a probabilistic approach, uses a precompiled topological map where natural landmarks like doors or ceiling lights are recognized by the robot using its on-board camera. Experiments have been conducted using the AIBO Sony robotic dog showing that it is able to deal with noisy sensors like vision and to approximate world models representing indoor ofce environments. The two major contributions of this work are the use of this technique in legged robots, and the use of an active camera as the main sensor
