Qbmove Output Shaft Doesn't Move Smoothly; One Or More Qbmoves Don't Activate - QB Robotics qbmove Advanced Kit User Manual

qbmove output shaft doesn't move smoothly

7.1
[Cause]
In some cases, qbmove's output shaft may get stiff and won't rotate smoothly when you try to
move it with your hands. This is not product failure but a situation caused by the tight
arrangement of the internal gears.
Tight gear arrangement is designed for precise motion control. So, you can see the robot moves
smoothly without a problem when the assembly is finished and power is supplied to each of
qbmove actuators
[Troubleshooting]
_____________________________________________________________________________
Solution 01
Turn the output shaft in the opposite direction first and try again to turn in the desired direction.
If you can't provide enough force, use a provided flange to rotate the output shaft. Much greater
torque can be leveraged and it's easier to rotate the shaft.
Solution 02
Connect qbmove to the PC and run "qbmove GUI". Make sure that the sliders of position and
stiffness are in zero position, then activate the qbmove.
Once activated, you can move the device by moving the sliders. To reset the position to zero,
click on "Zero" button. In this way, shaft will go to zero position and minimum stiffness
configuration. You can then use the sliders to verify the correct behavior of the qbmove.

One or more qbmoves don't activate

7.2
[Cause]
The angular positions of actuator's internal shafts are too far from zero position.
[Troubleshooting]
_____________________________________________________________________________
Solution 01
Turn the output shaft back near the zero position. If you can't provide enough force, use a
provided flange to rotate the output shaft or move directly the assembled robot.
Solution 02
Connect qbmove to the PC and run "qbmove GUI". Then click the button "Get Measurements".
If one of the positions is higher than 13000 ticks, follow "Solution 1". Then you can try to activate
the device.
