'z' values of 'mss_center'

Posted by Yongjin over 1 year ago

It seems that the values of ‘z’ in ‘mass_center’ are not returned.

Could you check if it is intentional or not?

I copied the part from the simulator source codes.

class OsimModel(object): … def compute_state_desc(self): …
## Other res[“misc”] = {} res[“misc”][“mass_center_pos”] = [self.model.calcMassCenterPosition(self.state)[i] for i in range(2)] res[“misc”][“mass_center_vel”] = [self.model.calcMassCenterVelocity(self.state)[i] for i in range(2)] res[“misc”][“mass_center_acc”] = [self.model.calcMassCenterAcceleration(self.state)[i] for i in range(2)]

That’s indeed an error, thanks for mentioning. It has been already addressed in this issue https://github.com/stanfordnmbl/osim-rl/issues/129 we will fix it in the upcoming update along with one more fix.
