And actually, if I get it on the stuck position I can make the wheel make an odd clicking sound.

Ok, I did some exploration and noticed that if I gently rotate the wheels with my hands, one rotates just fine but the other gets stuck at certain periods during the rotation. I tried disassembling Zumi to see if I could check the axels but I can't access that little black box.

I also noticed it gets stuck at the same point during the rotation each time. I think one of the gears chipped somehow and is causing problems. No idea how in the world that managed to occur; I've been extremely cautious with it. There's also no external damage, which I imagine would happen first.

The left wheel stops moving after about to seconds of motion, the left wheel stops moving. (So if I call forward() it makes a tight circle).

No idea what to do here. Could it be a hardware issue?

Hello Robolink,

I'm having an issue with lesson 6.1; Zumi does not seem to register the QR code. I modified the code so I could see through the camera but otherwise nothing else was changed about the canned code.

I'm unsure where to start to fix this.

@robolink_leila Ok maybe it's just background interference. Thank you.

I currently have Zumi about half-an-inch away from a wall and my IR sensors are currently readin 97 and 105 for the left and right front sensors respectively, so with the canned code Zumi would barely detects an object on the left.

I feel like the numbers shouldn't be this high. Is there a way to correct calibrate the infrared sensors?
