DAY 14

Today is furthering what we need to do to make the robot competition ready.

Here are the list of accomplishments:

Sensor Integrations:

2 IRs at front edge of robot
long range sensors
switch sensors
optical encoders
ground sensor readings

Mechanicals:

drive train change to rear wheel drive only
strengthen U-channel docking port with H-bridge and side bracing.
change rear wheel to larger wheel for tilt effect, allowing the sensor arm to dip closer to ground.
add rubber bands to secure wirings
add zip-tie whiskers to fan out and cover sensor blind spots

Programming:

modularize and tested the following:

forward
reverse
stop
left turn 90 degrees
right turn 90 degrees
line detection
scan for can


Needs further work:

RGB can color sensor readings: too erratic for blue and green, often reading are 330 and above.
Needed to work on angles and placements.

All mechanicals functionings--no further tweaking required

More in depth programming:
once can is found, what do you do?
