February 21st. The day had finally come for the critical design review (CDR) presentation of all of our progress up until this point. When all was said and done, we were able to securely attach one of the arms to the robot and write a quick Thonny script to actuate the wheel motors and demonstrate the "flapping" system.

Next, we will be looking to reprint timing belt pulleys (heat inserts kept falling out of previous prints), assemble and attach the other arm, and determine a method for experimentally measuring the pressure needed for the robot to remain put in the pipe.
