Based on what is available for purchase in the store, I would say the MPU9150.
 ControlCommand("MPU9150", Init) sleep(100) :loop IF ($AutoPositionStatus = true) print("AutoPositioner already running...") sleep(2000) goto(loop) ENDIF ControlCommand("MPU9150", RunOnce) print ("x: " + $MPUAccelX) print ("y: " + $MPUAccelY) IF ($MPUAccelY > 8000) print("Getting up from front") ControlCommand("Auto Position", AutoPositionAction, "Getup") waitfor($AutoPositionStatus = false) ELSEIF ($MPUAccelY < -8000) print("Getting up from rear") ControlCommand("Auto Position", AutoPositionAction, "stand from sit") waitfor($AutoPositionStatus = false) ENDIF sleep(1000) goto(loop)

Are you sure you are using it properly? Have you initialized it? Show me your script?

this is what the (?) mark chows

That's great but you need to write a script like below (DJ's code for the mpu6050) in order to use it the way you saw on the video DJ made of JD getting up after falling over... This is for the MPU6050 not for the MPU9150, however the code can be easily adapted to work with the MPU9150
 ControlCommand("MPU6050", Init) sleep(100) :loop IF ($AutoPositionStatus = true) print("AutoPositioner already running...") sleep(2000) goto(loop) ENDIF ControlCommand("MPU6050", RunOnce) print ("x: " + $MPUAccelX) print ("y: " + $MPUAccelY) IF ($MPUAccelY > 8000) print("Getting up from front") ControlCommand("Auto Position", AutoPositionAction, "Getup") waitfor($AutoPositionStatus = false) ELSEIF ($MPUAccelY < -8000) print("Getting up from rear") ControlCommand("Auto Position", AutoPositionAction, "stand from sit") waitfor($AutoPositionStatus = false) ENDIF sleep(1000) goto(loop)

mpu 6050? in his video and text it chows mpu 9150 but i try yours.

Dunning-Kruger · Answer

I know... the example is for the mpu6050 ... but tweaking it a little and it will work with the 9150,,, Download the example project from the cloud for JD and the MPU650....

withs one do i have then?

Nomad 6R · Answer

so i choose the mpu 9150 in ARC?

CochranRobotics · Answer

Yes. I dont have one, but I would believe that this would be right based on what is available for sale in the store.

nomad TMBS , you are very close , yes use the MPU9150, but first add an MPU9150 control to your project. Then look at the variables in the MPU9150, they are not the same as the MPU6050. Try this, ControlCommand("MPU9150", Init) sleep(100) :loop ControlCommand("MPU9150", RunOnce) $initheading=round($CompassHeading,0) print($initHeading) print("AccelX AccelY AccelZ CompassHeading") print($accelx + " " + $accely + " " + $accelz + " " + $initheading) print("CompassX CompassY CompassZ") print($compassx + " " + $compassy + " " + $compassz) print("GyroX GyroY GyroZ") print($gyrox + " " + $gyroy + " " + $gyroz) sleep(1000) goto(loop)

CochranRobotics · Answer

Nomad will post the working script. For some reason, the variables were not recognized in the script (even using the correct names). We had to assign new variables and then assign these variables the values from the AccelX and AccelY variables and then use the new variables in place of these in the script. He will post it and you will see what I am talking about. Weird.

CochranRobotics · Answer

from what I remember, this script worked but I am not connected to his computer to see anymore.
 ControlCommand("MPU9150", Init) sleep(100) :loop #Added these because $AccelX and $AccelY were not recognized later in the script for some reason. $XAccel = $AccelX $YAccel = $AccelY IF ($AutoPositionStatus = true) print("AutoPositioner already running...") sleep(2000) goto(loop) ENDIF ControlCommand("MPU9150", RunOnce) print ("x: " + $XAccel) print ("y: " + $YAccel) IF ($YAccel > 8000) print("Getting up from front") ControlCommand("Auto Position", AutoPositionAction, "Getup") waitfor($AutoPositionStatus = false) ELSEIF ($YAccel < -8000) print("Getting up from rear") ControlCommand("Auto Position", AutoPositionAction, "stand from sit") waitfor($AutoPositionStatus = false) ENDIF sleep(1000) goto(loop)

here's the script for the gyro
 ControlCommand("MPU9150",init) sleep(100) :loop print("start of loop") $XAccel=$AccelX $Yccel=$AccelY if ($Autopositionstatus=true) print("Atopositioner alredy running") sleep(2000) goto(loop) endif ControlCommand("MPU9150",RunOnce) $XAccel=$AccelX $YAccel=$AccelY print ("X:"+$XAccel) print ("Y:"+$YAccel) if ($YAccel > 8000) Print ("Getting up from front") ControlCommand("auto position",autopositionAction,"get up") Waitfor($Autopositionstatus=false) $XAccel=$AccelX $YAccel=$AccelY print ("X:"+$XAccel) print ("Y:"+YAccel) elseif ($YAccel<-8000) print ( Getting up from rear") ControlCommand (Auto position",AutopositionAction,"stand from sit") $XAccel=$AccelX $YAccel=$AccelY print ("X:"+$XAccel) print ("Y:"+$YAccel) endif sleep(500) $XAccel=$AccelX $YAccel=$AccelY print ( End of loop...restarting") goto(loop)
