 | | downloading the pcode during assembly

|
hi, I am during the assembly phase where I am supposed to be able to download the pcode to the handy board. I've placed on my handyboard a UM62256A-10L as RAM a MC47HC132N and a PICVUE 16x2 LCD PVC160203P All the test from the handyboard assembly (...)

(...) I would suggest shutting it down early (say 5 ticks early) and using a "jog" mode whereby brief pulses are sent to the motor to move it the remaining distance. Lets say you shut it off at 19 (targeting 24) and the motor/load's momentum carries (...) (24 years ago, 12-Jan-01, to lugnet.robotics.handyboard)

(...) Actually I was simplifying too much here. My goal is to be able to execute a relatively accurate 90 deg. turn to "round the curve" in a narrow hallway and to be able to spin on axis (robot is circular) a full 180 so I actually can count on (...)

(...) No, your conclusion is too broad, simply stated if you don't monitor motor current (and to some extent model the inertia of the motor) in software, then your damping algorithm (which is effectively a constant based on your description) won't (...)

(...) It certainly helps. I guess I'll stick to my kludge... it's easier. ;) So in order to do effective rotation sensors I need to monitor not only the rotations, but the power applied to the motor as well? That seems fairly complex but I guess (...) (24 years ago, 11-Jan-01, to lugnet.robotics.handyboard)
