Online observation, estimatation, planning, and control for a Franka Panda Robot operating in NVIDIA SRL's simulated kitchen environment.
SS-Replan supports both Python 2 and Python 3.
- Install Git LFS
$ pip install numpy scipy pybullet sklearn$ git lfs clone --branch master --recurse-submodules https://github.com/caelan/SS-Replan.git$ cd SS-ReplanSS-Replan$ git lfs installSS-Replan$ ./pddlstream/FastDownward/build.py release64SS-Replan$ cd ss-pybullet/pybullet_tools/ikfast/franka_pandaSS-Replan/ss-pybullet/pybullet_tools/ikfast/franka_panda$ ./setup.py
It's also possible to use TRAC-IK instead of IKFast; however it requires installing ROS ($ sudo apt install ros-kinetic-trac-ik).
SS-Replan$ git pullSS-Replan$ git submodule update --init --recursiveSS-Replan$ ./run_pybullet.py [-h]
Executed using the IssacSim 3D robot simulation environment.

- PDDLStream: Integrating Symbolic Planners and Blackbox Samplers via Optimistic Adaptive Planning
- This repository uses PDDLStream to perform hybrid robotic planning.
- PDDLStream leverages FastDownward, a classical planner, as a discrete search subroutine.
- Common robotics primitives are implemented using PyBullet.
