Hitec Servo for a Robotic Arm - Electronic Circuits Projects Diagrams Free

YAN-1 · 2nd April 2006, 07:37 AM

Hi everyone. I am about to build a robotic arm and I think I will use the Hitec HS-805BB servos with a certain gearbox that I found. However, I can't really determine its range of motion. In this link: http://www.servocity.com/html/hs-805bb_mega_power.html it says 'Operating Angle: 45 Deg. one side pulse traveling 400usec'. Does anyone know what that means? I thought these servos either had a 90 degrees or a 180 degrees motion range. If anyone has had experience with this servo or any of the Hitec servos, please help me out. I appreciate it. Thanks a lot.

hi.
Analogue servos require that the position pulses (1 - 2 mS) to be refreshed every 20 mS, or they wont work. Digital servos are pulsed with 400uS signals, so yours must be a digital servo. 45 degrees is the travel angle.
