Subgroup Updates¶

Tested BFS. Works now.
Finish testing FSM.
Scheduler wrapper done soon.
TODOs:
- Translate Scheduler code to c++
- Make sure ported linefollowing code works
- Make sure everything interfaces correctly
- Get_worst_case_time function

Electrical

Parts and Board order. Hopefully will get parts in shortly before or immediately after spring break.

Mechanical

Fixed a problem with memory allocation which had broken scoutsim a while back
New EncodersControl class
Odometry hooked up to EncodersControl
- Both of the above need some debugging
Should set a time frame / goals etc. Seem to be regularly making little progress due to not having enough time.

Power prototype

Replaced broken FTDI chip with new one
- USB communication might work: haven't reprogrammed AVR since then, sometimes getting serial output
Added external pull-up resistor to pushbutton input, as internal one is flaky
- Pushbutton behaves correctly, but controller is still stuck on
Kevin suggests investigating behavior of !SHDN pin on LDO when disconnected, i.e. does it pull or float?
Would benefit from breaking out the pushbutton controller and hooking up a logic analyzer to it

Scoutfly routing

Julian made substantial progress on routing a reduced version of Scoutfly with most of the power path removed
Seems sufficient for SURG, will probably be able to ship out relatively soon
Should seek opinion of Kevin, possibly Brian and Tom

Personnel issues

Ben Shih no longer with us
Five people and two slow, tedious tasks
- Need to figure out how to parallelize workload more

SWE Demos
- Went well
- Colony bots run out of batteries
- Keep 2-3 good robots demo ready always!!!
