Continuos Rotation HS-311 Servo w/ Sharp IR
Nate_the_Great:
OK, two quick questions about adding IR rangefinder to the $50 robot: ???
1) If I do not use the rangefinder reccommended from this link
(http://www.acroname.com/robotics/parts/R48-IR12.html)
and instead use another similar one will I have problems connecting it? the one I ordered:
http://thebotshop.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=GP2D120XJ00F&Category_Code=CK
2) I see from the picture of the modified robot that the photosensors were not removed when the rangefinder was put on, were they not removed for a reason/ can they be removed when the rangefinder is added?

1) the rangefinder should work but if you really want to kick it up a knotch use 12.50 rangefinder like this one http://www.acroname.com/robotics/parts/R144-GP2Y0A02YK.html it is better and cost the same price.
2) ??? I really don not know but that is a really interesting question. Why dont you send a personal messege to the admin to see if he can answer that question to you. One's you get the answer send me a personal message with the answer. Pls put the topic title. ???
Nate_the_Great:
I ordered two HS-311 continuos rotation servos and they are very similar to the unmodified HS-311 I ordered for the Rangefinder, except their are dials with three wires sticking out of them (green, yellow, red). When I twist them they seem to make the servos reverse their rotation, with the rangefinder upgrade does it matter which position the dials are at to make the servos respond to the rangefinder? Because they don't seem to respond to the rangefinder unless they are in a certain position.
Admin:
Dials? What do you mean?
Also, you need to use unmodified servos for the rangefinder upgrade . . .

No reason to remove them . . . its what's inside (the source code) that truely matters :P
