0c874aa43a fix issue introduced in previous commit, related to 
btMultiBodyConstraintSolver friction/penetration handling
 2017-03-20 19:38:59 -07:00
Erwin Coumans
0b017b0f53 fix issue with btMultiBody friction in combination with soft contacts (friction should not re-use normal contact cfm/erp) 
implement friction anchors, position friction correction, disabled by default. Use colObj->setCollisionFlag(flag | CF_HAS_FRICTION_ANCHOR); See test/RobotClientAPI/SlopeFrictionMain.cpp. In URDF or SDF, add <friction_anchor/> in <contact> section of <link> to enable.
PhysicsServer: properly restore old activation state after releasing picked object
btMultiBodyConstraintSolver: disable flip/flop of contact/friction constraint solving by default (it breaks some internal flaky unit tests)

4db6fa9e29 update minitaur.py to use minitaur.urdf (instead of quadruped.urdf), also sort the legs in the same order as real hardware 
added test urdf files for minitaur with all fixed joints, or fixed knees.
added some stiffness/damping to minitaur legs (testing)

4ee09c264c Avoid using unitialized values. 
m_gravity was used before it was initialized. Simplest way to avoid
it is to call any method first after all values are initialized.

bbefc8fe7e Apply temporary stack-memory optimization, thanks to Jim Tillander 
(old pull request 316 https://github.com/bulletphysics/bullet3/pull/316)
You can disable this in the build system, by adding preprocessor define 'BT_DISABLE_STACK_TEMP_MEMORY'
