Status Updates: 11/19/10¶
Week of 11/12/10 - 11/19/10
Current Projects:
- New Assignments
- Willis Chang (whchang) and John H.
- Better terrain for hunter-prey etc. (Walls)
- SURG Mats (Paper, roads, reflective paint)
- Talk to photographer for getting more free large-scale paper
- Hardware (Nico)
- Will have it done by Monday night / Tuesday Morning
- Meet this weekend to put MUX boards on (Nico, Alex, Dev, Dan)
- SURG - Traffic Navigation
- Highways - Alex Z, Matt, Mark, Abe, James, Dev
- Intersections - Ben, Jeff, Priya, Alex L, Willis, Joseph, Vinay
- DEMO
- Barcodes - Dan J., John S., Willis
- Final Semester DEMO
- Clover track
- Use bar codes to detect which leaf you are on
- Adjust colors to reflect which line you detect yourself on
- Navigate intersection in the middle
- Have linefollowing code merged into Library
- DEMO should run for a long time without problems
- Put hat on 1 robot and film from above and watch as it traces out all leaves of clover
- SURG - Diagnostic Station - John H, John S, Chris M
- Mechanical assembly making good progress
- Exploring options for electrical side:
- Use a dragonfly board either as stand-alone or as an intermediate to a full-blown computer
- Use an Arduino as an intermediate to a full-blown computer
- Use a LabVIEW data collection system with a full-blown computer
- Obtain an Atom computer
- Does not come with an OS. Would have to troubleshoot this.
- George mentioned small USB devices which give you access to analog channels. Might have to write drivers for it, though.
- Use a camera for IR detection
- Evan has used this with a floppy disk part as a filter for IR
- Can test out this camera and see if it works, but we'll plan on it for now
- Evan has used this with a floppy disk part as a filter for IR
- Collimator
- Would be great for the robots
- Better to make one per pair of emitter/detector, rather than a whole ring at once
- If John H. can figure this out, maybe someone else can pick it up
- Scout
- Scoutfly Dan Shope, Kevin Woo
- Finished populating all the components, fired it up for the first time, got a nice power LED
- Something wrong with power rails, and after hours of debugging didn't figure it out
- Shipping the board to Kwoo for debugging
- Gumstix Jeff Cooper, Brad Neuman
- The gumstix boots, has pretty LEDs, and can be talked to through terminal. If anyone has a HDMI-mini cable we can also use the in-built GUI.
- Jeff is re-building the OS to have some needed features like GPIO-Event (http://docwiki.gumstix.org/GPIO_event) which allows us to automagically poll I/O lines
- Looking @ GumROS, which is a gumstix port of the Robot Operating System maintained by Willow Garage
- If we can't get gumROS working on the overo board, we can install ROS on top of Ubuntu(ARM)
- Strip out the GUI and other extraneous bulk that we don't need
- Sluggishness factor? Uncertain, but obviously there's a lot more overhead
- If we can't get gumROS working on the overo board, we can install ROS on top of Ubuntu(ARM)
- ROS Jeff Cooper, Brad Neuman, Dan Shope
- Shope has installed on Ubuntu, going through the tutorials
- Pretty slick system, gets you up and running very quickly once you learn some basics
- We'll probably code a lot in C++ & Python, which Colony doesn't use currently
- ATMega128RFA1 (AVR) Evan Mullinix, Chris Mar
- Option 1: Scheduler code from Austin Buchan, originally written for the mod-snake program
- This is on the W drive and will be added to the ScoutOS git repository
- Option 2: Scheduler code from Justin Scheiner
- Originally ported from a CMU class example code, talk to Evan
- Wireless library from nanoRK
- Coded by Max Buevich (my roomie) who is embarrassingly familiar with the RFA1
- AVR<->ARM Communications
- Option 1: Scheduler code from Austin Buchan, originally written for the mod-snake program
- Scoutfly Dan Shope, Kevin Woo
- Good old ticket ideas
- Reminder to start on some of these as assigned last week.
- Filter Design - Emily
- Rangefinders Fitting - Brad, Ben P, Megan
- From last week: Speak with Megan - Ben P
- Did this happen?
