            Today we started on our new challenge. We are asked to add a claw or some sort of lever to pick up two tetrahedral figures and stack them one by one on top of pipes. Although we have started this week, we are going to be on spring break from 3/22- 4/1. When we get back we will finish our assembly and proceed to finishing the challenge.                               This picture above shoes the shape of the object we have to make and use to place on the poles.

  WE FINALLY FINISHED. After long, stressful weeks of work. Our group has finally finished our figure 8 challenge. I am very happy and proud of our group for their motivation and their ability to keep trying. While some groups completely gave up, we continued to try and complete this assignment.                                                        

                                    We still haven’t got this robot working. The robot is currently at a point where instead of working consistently, sometimes it will finish completely and other times it messes up at the most random spots. So our focus is to fix all issue so that it works perfectly every time. We are working very hard to finish it especially because next week will be our last week here before we go on to spring break. 

  This week we have learned new information on why our robot may be acting up. The battery. We have learned that the battery's voltage level can affect how fast or slow the robot runs and the amount of power that it has to turn. With this knowledge we have created a "safe range" between 8.0-8.3. If our battery's voltage is higher or lower than this range, the robot will not do the specific angles and measurements that we have programmed. Because we've learned this, it has been easier and way less stressful to keep the robot consistent.

Yesterday in study hall Roche was able to finish coding the figure 8 on the robot and it worked perfectly. For some reason when we came in today the robot was completely wack. It wasn't turning at the specific angles programmed, we had no idea why, in one day, the robot went completely wrong. We tried tightening the wheels, restarting the system, and charging the batteries. It has been a very stressful week but we still have hope to finish this challenge.

This week our goal is to finally complete the figure 8 challenge and start on something new. Today when we started for some reason, our robot was completed out of control. Instead of going forward, or doing the specific movements we programmed, the robot would spin in circles by itself. For awhile we thought it was something wrong with the motors, we even took it apart and fixed one of the axles on the wheels. Nothing worked! we finally asked one of the seniors in our class for help and of course, they found the issue. For some reason the coding website had some issue working and we had to take certain steps to reset it.
