Justin: I took a look at the color and distance sensors and decided I’m going to take the laptop home today and try to get the code for them to work. 

Hugh: I replaced the skyscraper lift motor. The spool on the motor had started rubbing against a support causing excessive friction. The motor gears stripped out. We replaced and repositioned the motor to prevent repeat. I also verified that the new lighter-weight capstone will lift off of its arm without binding. It is good.
