Objectives / Systems Hypotheses, tests, observations, conclusions, plans
Tetrix Treads measured dimensions

Ordered Tetrix Treads (2 kits plus accessories) have arrived.

  • Idler wheel diameter = 2.560"
  • Tread thickness = 0.175"; Tread width = 1.560"
  • Idler / Tread effective diameter = 2.910"
  • Pitch (19 1/16" for 50 links) = 0.381" (0.384" measured in CAD model)
  • Drive sprocket had 20 teeth - pitch diameter = 2.445"
  • Braden, Myles, Amal, Wade,and Trevor were helping out with the intake
  • We measured the length and width of our mini chassis. We also used polycarbon glass as well.

Tasks Reflections
Drive Chain treads
  • Josh worked with Gary and Daniel to attempt to put together the tank treads. They put the rubber tread grips into the treads. This took a long time and Gary reported that his arm ached after he slid all the pieces into their proper place.
  • It was really frustrating and time consuming! Josh and Gary found it pretty tedious and were happy to see the treads done. However, they didn't climb very well, and more ground clearance is clearly required. They are also considering adding wheels to make driving onfield easier.
Possible scoring methods
  • Braiden, Wade, Myles, and Trevor brainstormed ideas that would intake the debris and move it into the storage system. The intake method found to be most effective was using axels and a motor with surgical tubing attached in order to suck the debris in.
