12:00 AM drekipus: but rotation is just the difference, or the arc, divided by the radius, gives radians.
12:04 AM rue_shop3: another way I was looking at it, is that each sensor reads the tangential rotation around the other
12:05 AM rue_shop3: but that was for small wheeled robots that dont slip sideways
12:13 AM drekipus: ye
12:14 AM drekipus: what I realised is that this is an omniwheeled robot, but has a "differential-esque" tracking.
12:14 AM drekipus: the only difference is that translation is in two directions, but it can still "drive forward" and "rotate"
12:15 AM drekipus: so these are differential drive equations
12:58 AM rue_house: yea!'
02:10 AM Jak_o_Shadows: Is a stepper any easier than a rotary encoder?
02:10 AM Triffid_Hunter: Jak_o_Shadows: nope. basically the same, except the voltage level of the signal is proportional to the speed which is just an added complication
02:14 AM Jak_o_Shadows: yeah.
05:27 AM drebo: want to build shit but got called into work tomorrow
05:27 AM drebo: i angerz
06:49 AM Jak_o_Shadows: I should have done more stuff
06:49 AM Jak_o_Shadows: through that reminds me, I need to set the alarm clock
06:50 AM deshipu: on fire
06:56 AM Jak_o_Shadows: nah
06:56 AM Jak_o_Shadows: via bluetooth
06:57 AM Jak_o_Shadows: From PC, as I have not written the phone app yet
01:54 PM logicmoo is now known as dmiles
07:12 PM pennywise is now known as davr0s
