Hello,
I've been working with a few different types of sonar modules, the Parallax Ping, the SRF04 and the SRF05 and in ARC using either the radar scan, distance, or collision detection the "ping" interval can only be set from 100ms all the way up to 60000, is there a way to set it lower to say 20 or even 10?
I also noticed that the distance measurement is off as well, the sensors I have can detect as close as an inch away, but ARC does give an accurate distance. I have changed my wires and tried the sonar that came with the EZ-Robot kit, same issue.
Thank You
@Charley you won't run into any issues with the wifi module. The EZ-B is communicating with the ultrasonic sensor, not the computer.
The connection speed between the computer and EZ-B will automatically adjust based on the communication method used. The wifi module will be much faster
@DJ thanks, I actually had one of those days where I probably shouldn't of been working on electronics.. I was setting up the Wifly controller and had to update the firmware, well that was the easy part..... After the firmware update to the Wifly, it rebooted and must of said something bad to the EZ-Controller because my robot basically flew off the table full speed right behind me and hit the floor, result was a few new swears (okay lots), a stripped servo, and I also did something to the LM1084IT-5.0 reg as it's no longer outputting 5vdc, more like 2.6vdc.
Before this little mis-adventure happened the only issue I had with the wifi controller was that it seemed to stutter when controlling the sonar servo using the sonar control, but when using the bluetooth it did not, the debug window did not show any errors either so I was trying to figure out what was causing the stuttering when using the wifly controller(I figured between the firmware update on the wifly and maybe fine tuning some settings, you know...).
Anyways i'll have replacement regs in a couple days and hopefully be back up and running.
Thanks again
PS - good thing ARC doesn't have an option to repeat what someone says, cause it would of had to work pretty hard on what I was saying today...

HAhaha, sounds like an adventure! I was having a meeting with someone the other day who had a funny similar story. He said many years ago he built a very large robot powered by car batteries in his small apartment. He didn't put an on/off switch because it was remote controlled. Well, he had some interference and the robot went insane! Started driving around smashing into things. Apparently it took out a coffee table and a door!
So... consider yourself lucky
LOL, considering my work bench has all my test equipment on it I am very lucky it was pointed the other direction.. I've already put a second switch in so that the motor power can be turned off while the rest of my robot is running..
Oh that's a smart idea!
I usually hang or raise my robots so they are off the ground while i configure them
