Houston Championship - Newton Division

Robot Specs (what the robot at Houston Championships has):

Drivetrain:

  • Single Speed Gearbox with three Mini CIMs
  • Chain Driven 6WD Drop-Center
  • 4" Colson Wheels with 4-Axis CNC Milled Treads

Gear Chute:

  • Passive Gear Chute receives Gear at loading station
  • Servo actuated flaps allow for easy transition of Gear into mechanism
  • LED Light Strips for feedback indicate status of Gear within robot

Gear Ground Intake (not pictured):
This mechanism has replaced the ball intake shown in image

  • Dual roller system actively intakes the Gear from the ground
  • Top roller of compliant wheels compress against Gear, bottom latex roller kicks the Gear off ground
  • Driver Assist Camera on Driver Station allows for swift Gear acquisition

Fuel Shooter:

  • Two 775pros power the shooter wheel and brass flywheels
  • Custom Camera Module with Axis Camera, LED Light, and Peltier assist robot in autonomous aiming

Climber:

  • Two 775pros drive the climber spool for a 2-second climb
  • Miniature ratchet wrench locks the robot and prevents deactivation of touchpad

See you in Houston!

Interesting work on the wheels. Do you find they provide an appreciable performance increase?

From our in-house testing of wheel coefficients of friction, we saw an almost 40% increase in traction with the machined treads.

You can see how we machined the Colsons in this video.

Whaaaaat? 40%! That’s crazy. We outta try this, except I think we might get some strange looks from our machining sponsor if we’re asking them to run a bunch of rubber wheels on their 4th axis.

Side note, what Haas machine is that?

Super Mini Mill 2. Great machine.

You can get similar results with just a band saw and a jig if you just cut straight slots across the wheel. The diamond pattern is slightly better, but if you don’t have a radial arm saw or a cool jig on the mill or whatever it can get tricky.

QFT. We did this in 2014 and were really happy with the results.

Also, I always love the design of 696’s robots. Looks so clean.
