2019:Habitat

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

 

1/15/2019

Goals

• Complete design
• get CAD model correctly sized and designed

Accomplishments

• Start 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?

Goals: 

• 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:

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

 

 

Goals: 

• Complete working prototype
• figure out all forces

Accomplishments/Creations:

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

Learned:

• 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:

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

Concerns:

• 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."
