Week 4

Summary:
  • Continued clay mold for Mario
  • Began building internal head structure
  • Coded servo motors
  • CADD sketch for the JAW
  • Latex is coming!
What's happening!
Today in lab, Gary started working on the CADD model for the dragon's jaw. Because we are planning on making the jaw open and close, it is best if we 3-D print it so that the hinge is built in. He is making the bottom and jaw separately and interlocking the two with a pin. 
Peter started working on the inside structure for the dragon head. We decided it was best to K'Nex so there is some rigidity in the piece. Pete grew up playing K'nex so he loved to be a little kid again!
James and I soldered a board and wires together to create a permanent pin compartment. 

Arjun started working on the code for the servo motors while I finalized the code for the ultrasonic sensors. There is a slight problem though, a single LED stays lit no matter what the sensor reads. We have checked every source of error, between coding, electrical and logical. We cannot identify the source of this error. On a slightly less negative note, the dragon head is giving Kate some trouble. The front snout of the head cannot support its own weight and fell off. We have since repaired the damage.
On a lot more positive note, Professor Terranova ordered two gallons of Latex which should hopefully arrive by Tuesday!
