My robot is having a hard time getting around and I think that it's because the
motors seem to be sticking. Even on my linoleum floor, my little tank robot
often gets stuck and goes in slow circles, because one motor gets stuck. Once I
nudge it or pick the robot up, the motor kicks in again but only for a little
while and then gets stuck again a few seconds later.
I am thinking that the motors need lubrication. Is this a good idea and if so,
what type of lubrication to use? I have WD-40 and Tri-Flow, a teflon-based
lubricant that is used for bikes, skates, etc.
Would either of these work and not damage the motor?

You may want to check if your motors are the new type 9V geared motor (#43362).
If so, please be aware it is prone to failure, the first sign being sticking. Pl
see my previous post on this ailment:

No amount of lubrication is going to help. In due course the motor will become
permanently stuck and useless. Such is the natural history.

Is this triggered by time or by usage? (i.e. will a motor that is run more
wear out faster?)

Both. Likely due to bad design and/or manufacture.
Someone at TLC is supposed to be looking into it. But I do not know what is the
outcome.
