Title: Will this work on new 50 buck robot?
Post by: NOOBinDistress on June 03, 2007, 08:36:57 AM

I am considering buying HITEC HS-81 HS 81 HS81 MICRO SERVO SERVOS JR Z instead of HS 311 servos for my second robot.I was wandering if these servos would work and if they would work on the updated part of the tutorial where you need a third servo? Please help thanks.

The Hitec HS-81 (http://www.servocity.com/html/hs-81_micro.html) will not work for the robot wheels cause the datasheet says its not modifiable for 360 degrees. It will work for the scanning sharp IR since it should not be modified for that.

If you use a different servo, you may need to tweak the signal pulse width a bit.

For example in my code, if you see

servo_right(41);

you might need to change it to say

servo_right(45);

or something like that until the servos do what you want.
