yunfeibai d383799d97 Merge remote-tracking branch 'upstream/master' 2017-05-22 22:23:55 -07:00
yunfeibai 3eb974f66f Add kuka grasping block playback. 2017-05-22 22:23:01 -07:00
Erwin Coumans fd40ba424b test for knee joint limits under position control 2017-05-21 11:00:15 -07:00
Erwin Coumans 79e2c10506 add second humanoid_running_3.py example with 3 humanoids, for testing. Created a humanoid_symmetric_no_ground.xml and ground.xml: 
if the ground is duplicated, simulation is unstable (too many contacts in the same area?)
 2017-05-12 17:17:27 -07:00

also remove user constraints, if removing a body
 2017-05-04 13:14:24 -07:00
Erwin Coumans eb7cf38293 Add option to --useKitchen=1 to VRGloveSimulatorMain 2017-05-02 22:33:42 -07:00
Erwin Coumans 07992fe61d Improve MJCF import, to allow reading of friction parameters, including spinning and rolling friction, with some rudimentary 'default class' support.

 2017-05-02 18:05:36 -07:00
Erwin Coumans af6bf8ddc8 plumb URDF/SDF audio_source into PhysicsServerCommandProcessor, allow to play sounds on collision ! 
See also https://youtu.be/eppOjTfx5Jg for a first test, and this modified URDF how to add sounds:
https://github.com/bulletphysics/bullet3/blob/master/data/plane_with_collision_audio.urdf
Add the --audio flag to enable sound in pybullet/Bullet-C-API
 2017-05-01 11:14:09 -07:00
Erwin Coumans 2a2c18e959 add more tinyaudio preparation, some test wav files, play sound on collision events. Will expose this in the C-API to pick wav files and collision threshold levels etc. Use the premake --audio flag to try it out. The TinyAudio example in the ExampleBrowser works on Mac, Linux and Windows, you can play notes by pressing keys. 2017-04-29 10:32:30 -07:00
Erwin Coumans dfc1800065 remove the goto's from the source code (came from http://github.com/thestk/stk toolkit) 
add test wav file

friction anchors, arm64 premake
 2017-03-20 11:48:44 -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)
 2017-03-20 10:58:07 -07:00

added some stiffness/damping to minitaur legs (testing)
tiny_obj_loader, don't crash on invalid texture coordinates
btMultiBodyConstraintSolver: sweep back and forward to reduce asymmetry

Erwin Coumans fdd517e00f First step towards a MuJoCo MJCF importer for Bullet. It can load the humanoid.xml, ant.xml and some other OpenAI GYM asset files.
