Servos Moving Forward

Hi Guys and and Girls,

i have got K9 responding to voice commands, including some responses from him verbally. so things are going great apart from...

when i ask him to move forward his servos respond, but only for a second (or less) and then stops, yet if i ask him to reverse his servo's keep going until i ask him to stop.

originally i thought it was due to the IR sensor interfering, so i disconnected this and repeated to test, with the same results.

any ideas?

confused

HI all,

i finally got my laptop of the kids (homework to do, so can't be mad), i have now uploaded the "K9" file to the cloud, now i have noticed that before i connected my EZ B to Builder, all seemed to be OK (after removing the "auto position servo control" and going back to the "modified servo panel", yet after connecting the EZ B to my network and trying again the same issue occurred.

any ideas?

thanks in advance for your/any assistance

Have you actually paused the sharp collision control or just unplugged the IR sensor? If you just unplug the sensor but not pause the control the robot won't move forward...

EDIT Just tried your project on 2 modified servos.... It works perfectly if you pause the Sharp Collision control...

Is there a reason you are using the sharp radar control and the sharp collision control in the same project? They both control the Movement Panel so it's probably a good idea to use one or the other, but not both...

Hi @Richard R,

I had the senor disconnected for the last trail. I used both of the ir control panels as a "sense" check, but will trial later with your suggestions and advise back.

Thanks @Richard R.

had a play and swapped the IR sensor over to a ping sensor and the forward movement is now operational.

this has allowed me to understand why K9 is not moving in a straight line, it's due to the weight shift on the front swivel castor. when moving forward the caster has to go 180 degrees before it reaches its driving position, causing K9 to "veer" of track. this is evident as when he reverses, he does so in a straight line as the weight and power are coming from the rear. so a double thanks:)
