Robot can walk all features button working, only when off the legs wrong directions, my old hexapod not like this hmm
Already change UNO and new ssc32 with new one,
Already trying use firmware 2.04gp.abl and 2.07egp.abl both got same problem,
dont know the problem is from the hardware or the software
Indeed, odd behavior, especially given that the robot otherwise works normally (so the electrical connections are likely correct). When you rotate the robot in the last video, the six body servos are not powered anymore, which is correct.
Not sure if kurt ever saw that behavior (or is available to take a look), but the Basic code dates back quite a while, and the chip itself has not been made for many years. As a learning experience, if others are unable to help and you really want to take a look - open up the code.
Sorry I have not played at all with RC servos in many years… Except for one servo recently to compare movements versus some other servos.
From your videos, I really could not tell much from them, sorry.
As @cbenson mentioned, it sort of looked like gravity… By this it looked like maybe the servo(s) was not properly holding a position or going to a new position. Again my RC stuff is very very rusty.
If it were me, that I would look at include:
a) Does it ever hold a position? If not, maybe Bad Servo, maybe bad Gear in servo, maybe servo wire issue, Maybe connected to wrong pin on SSC-32
b) Works some times but not others… Again maybe bad servo/wire… Again have had gears go bad in servos, especially withe cheaper servos. Or sometime you have wires that get caught in joints or are not long enough, and either you end up with shorts or end up losing signal.
c) If the servo is working but always going the wrong direction. Then …
On many hexs the left legs are built different than right legs, so Check that you have 3 left and 3 right
All same type of servos? Some go opposite direction. The hex config file allows you to invert the signals for most/all servos…
That is probably all I can think of for now as again been a long time!
