Habitat climb/descend design decisions, notes, and specifications go here!
 

1/15/2019

Goals

  • Complete design
  • get CAD model correctly sized and designed

Accomplishments

  • Started actual CAD

Learned

  • 775 with gear box is  too long for back foot

Questions/Ideas

  • Is direct drive 775 too little power to move the robot?

1/13/2019

Goals: [edit]

  • Create 1x1 tube in incentor
  • mount tube to cylinder mounting brackets 
  • mount tube to cyclinders
  • create bracket assembly
  • create cylinder mount in CAD

Accomplishments/Creations:[edit]

  • Created the 1x1 tube in cad
  • assembles the tube w/ the bracket assembly
 

1/12/2019

 

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

1/9/2019

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."
