Expose this btMultiBodySphericalJointMotor through PyBullet.setJointMotorControlMultiDof
Expose PyBullet.getQuaternionSlerp
Improve PyBullet.setJointMotorControlMultiDof
Improve humanoidMotionCapture.py with slerp and using setJointMotorControlMultiDof
Expose  btMultiBody::spatialTransform
Fix btMultiBody::setupPlanar from DeepMimic codebase
Add support for multidof joints in btMultiBody::compTreeLinkVelocities, thanks to DeepMimic codebase @xbpeng
