Is there going to be a diference if I put the sensors a certain distance a part. (closer to each other is better, or vise versa)

BTW I'm done with the "motherboard" of the robot. Ugliest soldering I have ever seen. and ruined the pc board a bit :o   150watt gun FTW 8)



zamboniman60:
for future reference, 30w is plenty for almost everything, and 25 is usually better...

i'd recommend making them position adjustable so you can play around with what is best for your robot. the physically closer the sensors are, the less light difference there will be between them. typically 2 or 3 inches is what i'd do.

Isn't tht bad? don't you want there to be more diference so it'll be easier for the robot to see a diference?


I got the servo's today(they were in the mailbox for 7 hours  >:( cause I didn't know they came) I got free upgrade to the 325HB with a baggy of tootsie rolls :o 8) , but they have diferent mounting hardware than admin's did   :-\ . also there was no big red servo horn that was in the pic on the site >:(

maybe I should just change the thread title to $50 robot blog  :D

yeap its bad, you want more difference. you could also have them right next to each other, but angled at say 100 degrees from each other. its all personal preference . . .

yea its hard to predict what is included with the servos :-\  and it changes occasionally, too.
ive had to once go out and specially buy the big servo horns cause my design really needed them but the servos didnt come with them.

gotta love the candy servocity gives out :P
i think they do that for big orders, not sure . . . i always do big orders . . .
