Goals: [edit]

  • Complete working prototype
  • figure out all forces

Accomplishments/Creations:[edit]

  • 2 versions of a prototype that work without weight
  • Good CAD made and lots of math

Learned:[edit]

  • There is too much friction to slide up the skid plate the way we are now
  • We need bigger pistons to life the full robot

Questions/Ideas:[edit]

  • Idea- Have 4 pistons facing straight up, and have a motor on the foor to drive us onto the step.

Concerns:[edit]

  • Amount of PSI needed to life robot
  • weight
  • space if we have big piston in the front or middle

Prototype of robot propulsion for hab designed and tested. Mechanism broke after 3rd attempt

Excerpt from Test 3 Results  "Level 3 scale in progress, Try #3 - 12" height, one 9" piston, 80psi."
