b027bc92df Fixing issue where mass of motors is uneven
Mass of motors was being tilted to the left, due to FL hip motor and RL hip motor having a mass of 1.095 and FR hip motor and BR hip motor having a mass of 0.241. This led to issues with the laikago tilting. May require further investigation to see if the laikago is at the proper center of mass!

03e897d1f5 replace deep_mimic policies by versions trained using PyBullet, backflip works better now. 2019-02-24 20:12:18 -08:00

bdf9b10246 more work on pybullet_envs.deep_mimic.
allow btMultiBody to not wakeup (for some RL experiments)
move deep_mimic motion files to data/motions folder, so we can use the args files unmodified.

9bddca873c allow pybullet_envs.deep_mimic.testrl --arg_file run_humanoid3d_backflip_args.txt to perform a backflip. Can only backflip twice, then drops on ground.
this deepmimic is still very slow, due to slow mass matrix/inverse dynamics computation. once spherical motor drive is enabled, it should be fast(er)
move pd_controller_stable to pybullet_utils for easier re-use
add plane_transparent.urdf to pybullet_data
allow spacebar in keyboardEvents (Windows for now)
