Week 2

Goals

  • Layout the floor of the workshop to test our prototypes

  • Design & Build our Drivetrain / Chassis (maybe complete build before we leave?)

  • Design a prototype "Plow" that can push cones into a ground junction

  • Brainstorm ideas for Signal Beacon

  • Assemble our low junction

Meeting Notes

  • Students laid out a 'field' on our floor

  • Students sized out different aluminum channel lengths to decide on a chassis

    • Decision was made to mount all motors 'vertically'

    • Decision was made to go 'as small as possible'

    • Decision was made to try and keep the cone plow 'inside' the robot; not outside

  • Some students worked on building the Chassis

  • Other students worked on designing how to push / grab / lift cones and began prototyping with cardboard

Game Field Notes

  • Junctions are about 23.5 inches center-to-center

Chassis Notes

  • Hole pattern

    • Channel is designed into a cube ( 48mm wide, 48mm height, and 48mm deep per hole)

  • Wheels

    • Minimum length for wheels with motors enclosed in chassis is a 14-hole channel. (360mm / ~4.25in)

    • Wheels can be mounted vertically (straight up) if we want to use shorter channel

  • Wheels

    • Wheels are 96mm diameter

    • Wheels will extend about 48mm (~1.9 in) out from the center of the axle's hole on the wheel side (depth of chassis)

    • Wheels extend out of the chassis by 40mm ( ~1.58 in) in the front view (width of chassis)

    • Wheels have about 24mm (0.9 in) clearance from the ground to the bottom of the chassis

  • Controls hub and wiring

    • Control hub will fit 4 circles in depth and 7 in width if laying flat (can be bolted into the hole patterns surrounding the holes)

    • If mounted vertically, the control hub can fit over the width of 1 extrusion.

Action Items

  • Finish building robot base (wheels and 1 motor need to be mounted) - Students

  • Begin programming Teleop (manual) mode (Students w/Mentor)

  • Wire Robot when finished (Students w/Mentor)

  • Test Teleop Mode (Students)
