MeetingMinutes20120213¶

Subgroup Updates¶

Warehouse Behavior - Priya¶

• Finished porting over all code (Yay group!)
• Wrote map implementation (mostly)
• Scheduler robot interface defined
  • Scheduler: provides task to robot (GET <spot #>, DROP <spot #>, MOVE <spot #> <spot #>)
  • Robot: executes task. Says "I'm Done!"
  • Something: provides time from A->B
    • Handles resource availibility
    • Knows where all robots are and their tasks

Tasks:

1. Leon finish path planning with help
2. Dan will write basic scheduler & something that handles time from A->B
3. Write Priority Queue implementation (for map & scheduler)
4. FSM for map

Mechanical - John¶

• Successful build day with Dan Monday
• continuing planning work
• I've Emailed Dan, more build times will be coming up, emails as they happen
• need to work on the meeting time, people aren't showing up

---

Forklift - Julian¶

• Mechanical
  • Played With RC forklift :)
  • Agreed upon belt based mechanical design
  • Misty started designing it in solid works. Should be done in 2 weeks.
  • Forklift motor selected as high gear ratio version of the scout drive motors.
• Electrical
  • Initial research into motor driver
  • Selected atmega168 as the micro-controller
  • System will run at 3.3V to conform to rest of scout logic level design

---

Simulator (and ROS) - Alex¶

• Nothing new done - sorry!
  • I blame hackathons.
• Plans for the week:
  • Sonars working
  • Odometry working
  • Smoother teleop
  • Wireless

---

Board - Abe¶

• Power board testing
  • Pushbutton controller datasheet gives conflicting information about how the enable output works
    • Not sure yet how the controller actually operates
  • Controller is stuck in the on position, so we can test other components
    • Julian made a little progress getting a bootloader on the AVR
• Scoutfly routing
  • Routed more of new power circuit on Scoutfly
  • Probably more than half of the initial placement is done, but it will still need tweaking

---

Low-level Software - Ben¶

• Driver level software being written
  • Both ARM and AVR
• ROSSerial being poked at
• Wireless library will be derived from wireless-new from Colony 3
  • Parts will be kept, parts will be discarded

Other Updates¶

• SWE Showcase Feb 19th (Sunday) 3:30-5:30
  • Need 2 people to be there (Alex & Leon)
  • Need hunter prey demo
  • Need singing robot demo
  • Need linefollowing demo
  • Need 2 people to pack Saturday
