Hi all, new to the group. Here's my first robot project ever - "SprintBot"  I do laser engraving and cutting as a business, so the chassis of the bot was fairly straight forward for me. I found the original idea and drawings here http://www.instructables.com/id/How-to-Make-an-OAWR-Obstacle-Avoiding-Walking-Rob/?newComment=true#comments and redid them to suit my needs.  As of tonight it walks and the servo points and the Parallax Ping triggers, but I get no readings from it :-( so... ...

Hi all, new to the group. Here's my first robot project ever - "SprintBot"

 I do laser engraving and cutting as a business, so the chassis of the bot was fairly straight forward for me. I found the original idea and drawings here http://www.instructables.com/id/How-to-Make-an-OAWR-Obstacle-Avoiding-Walking-Rob/?newComment=true#comments and redid them to suit my needs.

 As of tonight it walks and the servo points and the Parallax Ping triggers, but I get no readings from it :-( so... more work to be done.

 Here's the code I used to debug the sensor (gleamed from this site) -

main:    
 LOW PORTC 0
 HIGH PORTC 0
 PAUSE 1
 LOW PORTC 0
 LET DIRSC = %00000000
 PULSIN 0, 1, W0
 
 sertxd ("The value is ",#W0,cr,lf)
 pause 500   ‘ short delay
 goto main   ‘ jump back to the start

just added the sertxd stuff from the manual.

Any ideas on the ping??
