Tomorrow is the last day before the design expo. In the past few days we have gotten a motorshield and two stepper motors. Due to the extra weight the drivetrain added on the outside of the tank body, I have laser cut a support bracket to stop the separation of the body panels. Today Kevin and I went to the lab and have arranged to have the drive shafts 3d printed. Kevin received the sensor in the mail today, and has written the code for the operation of the tank. The final parts that we're waiting on, the gears to support the tank tracks, arrived at an East Boston sorting facility late this evening. If all goes as planned, we will have the drivetrain built, the code completed, and the body panels back in place by early tomorrow evening. We plan to meet as a group tomorrow to make the sprint towards the final project deadline.
