Conclusion:
-
Fix-ability: If you know what is broken, it should be relatively easy to fix as long as you are comfortable with soldering and have an equivalent part to replace it with. The device is relatively easy to take apart with just a standard Phillips screwdriver.
-
However, many robotics competitions do not allow the practice of modifying the device, which repair seems to be unfortunately considered under that. But if fixed, the device can be used as spare 'practice' robot part.
