Terry和Houndbot都是ROS機器人，以6061個鋁合金零件制造而成。項目的目標是要盡量讓這些機器人自主運動。
以下的Python腳本程序會監(jiān)聽「/head/tilt/smooth」的訊息，朝「/head/tilt」發(fā)布許多訊息，好讓伺服機轉到目標角度之前慢慢加速，再慢慢延遲旋轉。當訊息抵達「/head/tilt/smooth」時一定會呼叫「moveServo_cb」。這個回調函式會從-90到+90度之間每10度產生1個數(shù)值，追加到角度數(shù)組當中。「sin()」會取這個角度，數(shù)值從-1到+1慢慢增加。該數(shù)值加1之后，范圍就會變成0到+2，再除以2之后， 0到+1的曲線數(shù)值數(shù)組就完成了。然后再看看m數(shù)組當中，每當發(fā)布訊息時，就會稍微前進一點，范圍在r之內，直到1*r或是全范圍為止。
#!/usr/bin/env python
from time import sleep
import numpy as np
import rospy
pos = currentPosition + mi*r
print “pos: “, pos
pub.publish(pos)
sleep(0.05)
currentPosition = targetPosition
print “pos-e: “, currentPosition
pub.publish(currentPosition)
def listener():
if __name__ == ‘__main__’:
listener()
想要測試伺服機順暢的動作，就要啟動Python腳本，將訊息發(fā)布到「/head/tilt/smooth」，這樣一來即可檢視順暢的動作。
$ ./servoencoder.py
$ rostopic pub -1 /head/tilt/smoothstd_msgs/Float32 1
$ rostopic pub -1 /head/tilt/smoothstd_msgs/Float32 0
ROS當中的名稱也可以重新測繪。只要將「/head/tilt/smooth」重新測繪為「/head/tilt」，程序就能向伺服機發(fā)出命令，而不會意識到正弦曲線的數(shù)值在變化。
