41f9bb89e5 expose API to change the local inertia diagonal, pybullet.ChangeDynamics(objectUid, linkIndex, localInertiaDiagonal=[xx,yy,zz]) 2017-12-20 16:56:31 -08:00
erwincoumans
eb35cba740 expose local inertia diagonal in C-API, PyBullet, through the 'getDynamicsInfo' 
render the inertia boxes in examples/pybullet/examples/quadruped.py and examples/pybullet/examples/reset_dynamic_info.py
fix an issue where the original margin (0.04) was used to compute the inertia, instead of latest margin

cb23e6c102 Fix pybullet.calculateInverseDynamics in the case where #dof != #joints (fixed joints). We still don't handle spherical joints in pybullet (even though the underlying inverse dynamics and forward dynamics support it) 
Also, add a inverse_dynamics.py example, with URDF files. Thanks to Michiel Lutter for the report and repro case!
This fixes issue #1379 https://github.com/bulletphysics/bullet3/issues/1379

49a2771522 Implement the pybullet/Python equivalent of vr_kuka_setup_vrSyncPlugin.py 
In vr_kuka_setup_vrSyncPython.py, the vr controller is synced in Python, introducing a small lag
Invr_kuka_setup_vrSyncPlugin.py, the vr controller is synced in C++ at the same frequency as the physics time step (240 Hz by default)

acbe457d31 add option to statically link a plugin, select the postFix (to avoid naming conflict of multiple plugins functions ('initPlugin' becomes initPlugin_postFix) 
pass events (keyboard, mouse, vr controllers etc) to the plugin, and clear them after the tick callback, so that it doesn't interfere with Python 'getEvents'

1221c6d91d quadruped.py test, use generalized coordinates (not maximal coordinates) by default 2017-09-02 01:06:33 -07:00
erwincoumans
eb97e06280 fix minitaur.urdf: move lower-leg inertia to center, add missing collision for one of the motors, add contact parameters for friction_anchor, spinning friction, compliance (stiffness/damping) 
fix in indexing for maximal coordinates (unused by default, still experimental, requires many iterations for Minitaur due to extreme mass-ratio, hence use of reduces/generalized coordinates)
modify quadruped.py to test maximal coordinates
wrap angular servo (positional) target within [-PI,PI] in btGeneric6DofSpring2Constraint
add 'j' key to show body frames in wireframe/debug mode
