APM Copter not proceeding to 2nd waypoint

Posted by Venkatakrishnan on August 31, 2015 at 11:40pm

Hello Guys,

Need some help. I'm using APM 2.7 board with ArduCopter 3.1.5 firmware on a quad copter. When I plan a mission and fly in auto mode, it takes off properly. But it is not proceeding to the second way point. It maintains the same position that was given during take off. Has any one faced same or similar problems? Please reply as soon as possible.

      The WPNAV_RADIUS parameter has been set to zero somehow.  It's default is 200 (aka 2m).  With zero, the vehicle never thinks it's getting to the waypoint because it's never exactly on it.

      I'm going to exercise my rarely used moderator powers to fix the title of this discussion. All caps is generally interpreted as shouting.  Might want to reduce the caps in the user name you're using as well.. up to you though.

      Randy Thank you very much . It worked after i  set WPNAV_RADIUS to 200 cm .
      Thanks others also (Vishwanath and Khao Vu ) for showing interest in solving the problem and giving some valuable inputs.

    I've seen this reported a few times and it's almost always ended up being that the WPNAV_SPEED was somehow set to zero.
