“Shelbytron” An interactive robot to make pediatric physical therapy more fun

shelby's Issues

handle corners

drive down hallway

notes (for archive, not necessarily up to date things I need to do)

-move wires away from motor at all?
-analogWriteFrequency 20khz
-reduce separation between signal wires ("loops")
shielding for signal wires
resistors on signal lines
capacitor on power (1f 6.3v)
capacitor on motor
logic level shifter
run in slip rings
-slower clock signal from Arduino?

things to fix:
leds
left speaker goes out sometimes
go button red light channel
screen flickers
back IR sensor power wire has connection break where it connects to main power

tune wall following
Drive a U or L or just one length and turn around(wait for go at ends)
Faster/more tail wags
Start looking for hallway at specific distance, drive, turn, drive, wall follow
Add hall centering?
Check 5v power line
Calibrate battery monitor
Epoxy frame
Fix box lid fit
Fix wheel leds
Fix creaky wheels
And write down the tuning constants that work so you don't lose them.

• left turret falls aprart
• user manual
• screen flickers on bump
• start at any corner
• decode ir remote with joysticks
• backwards fast mode
• constant speed run away mode
• distance measure for 180
• scan during 180 for people in front
• stop faster when box sensor triggered
• better hall driving

error handling/ error/console screen

sweep wall and find angle

chase mode

add talking

change word mode from younger/older to on/off

mode dependent settings screen button (clockwise, CCW, lap)

ir screen framework

low battery warning, very low battery shutdown

think about what settings are hard coded, what settings are in a constant file, and what settings are on the sd card

pixycam

handle corners

at corner if sum of side distance sensors is very large
(look for corner if has driven distance or obstacle detected in front, do something different for first hallway?)
maybe require starting at corner? drive for a bit in a straight line when first started

add 3 bar display to battery display

smooth tail movement
