OMPL
The Open Motion Planning Library
Mark Moll & Lydia E. Kavraki
Department of Computer Science

Rice University

Houston, TX

USA
OMPL in a nutshell (1/2)
• Default motion planning back-end in MoveIt!
• Common core for sampling-based motion planners

• However, API not specific to sampling-based planning:

possible to add other planning algorithms

• Intended for use in:

• Education

• Research

• Industry
config. & database
server
robot path client
sensor data
MoveIt!
OMPL ... ...
OMPL in a nutshell (2/2)
• C++ library with extensive Python bindings
• Includes commonly-used heuristics

• Takes care of many low-level details often skipped in papers

• 35 (!) different sampling-based algorithms:
• Multi-query & single-query planners

• Optimizing planners

• Kinodynamic planners

• High level of abstraction for, e.g.,:
• State spaces: need not be Euclidean, metric, or even continuous

• State validity: more general than collision checking

• Path optimization objectives: more than just path length

• Extensive benchmarking facilities
Highlights of upcoming release (v1.1)
• New planning algorithms:
• Thunder & Lightning — Dave Coleman

• Informed RRT* & Batch Informed Trees (BIT*) — Jonathan Gammell

• Lower-Bound Tree Rapidly-expanding Random Tree 

(LBT-RRT) & Lazy LBT-RRT — Oren Salzman

• Updated T-RRT, bidirectional version of T-RRT — Ryan Luna

• Goal optimization included in path optimization — Ryan Luna
• Faster nearest-neighbors queries — Mark Moll
• Web-based planning & benchmarking — Prudhvi Boyapalli
Thunder — Dave Coleman

Motivation
• MoveIt planners
– Pros:
• Can be used right out of the box.
• Can solve difficult path planning
problems.
• Simple paths can be generated very
quickly.
– Cons:
• Tend to produce jerky trajectories.
• May introduce unnecessary robot
movements.
• Can be difficult to tune to meet special
cases.
• Post-processing smoothing step is usually
needed.
Stomp
• Stochastic Trajectory Optimization
Planner
• Optimization-based planner that
generates smooth well behaved collision
free motion paths in reasonable time.
• Original work by (Mrinal Kalakrishnan,
Sachin Chitta, Evangelos Theodorou,
Peter Pastor, Stefan Schaal, ICRA 2011)
• Code base was discontinued after the
transition to ROS-hydro more than 2
years ago
• Relevant moveit modules (now in
moveit_experimental) were also
discontinued
STOMP highlights
• Generates smooth well behaved
motion plans in reasonable time,
no need for post-processing
smoothing.
• Can Incorporates additional
objective functions such as
torque limits, energy and tool
constraints.
• Handles cost functions that don’t
need to be differentiable.
• Uses distance field and spherical
approximations to quickly
compute distance queries and
collision costs.
Current Status
• Updated the deprecated STOMP code base so that it
uses the latest in the MoveIt library.
• Available as a Motion Planning Plugin that can be
loaded by the move_group node and invoked from the
rviz Motion Planning panel.
• Can be easily configured with yaml files.
• Loads robot and environment information from urdf,
srdf and yaml files.
• Optimizes for obstacle avoidance and smoothness.
• Code available at https://github.com/ros-
industrial/industrial_moveit
STOMP Demonstration Videos
• Moveit Planners vs STOMP
• STOMP Demonstration
Future Tentative Work
• Allow for optimization of other relevant
objectives such as dynamics, energy, path
constraints, etc.
• Remove residual dead code (a lot of work).
• Better integration with the MoveIt pipeline
(MoveIt Setup Assistant?)
• Serialization of Distance fields generated from
large models.
• Handling of dynamic environment obstacles such
as octomap and attached bodies.

Other Development
 Selectively slow down trajectories
• Prevent falls and/or damage to robot or
environment
• Merged into upstream MoveIt!
 Parabolic time parametrization can
have acceleration spikes (github)
• Alternative cubic time parametrization
• Lives in fork for now
 Switch between MoveIt! and MIT's
Drake planning framework on a per
plan request basis
• Whole Body Motions

Conclusion
 MoveIt! provided required basic manipulation capabilities
• Easy and intuitive integration into complex system
• Sensor-based collision avoidance
 Potential areas for improvement:
• Consideration of balance constraints
• Whole Body Planning
• Optimization based planning
• Workspace analysis
- Inverse reachability
 Everything available on Github
 More at ROSCon 2015 talk

  • 49. MoveIt Community Meeting Jorge Nicho Research Engineer Southwest Research Institute
  • 50. Motivation • MoveIt planners – Pros: • Can be used right out of the box. • Can solve difficult path planning problems. • Simple paths can be generated very quickly. – Cons: • Tend to produce jerky trajectories. • May introduce unnecessary robot movements. • Can be difficult to tune to meet special cases. • Post-processing smoothing step is usually needed.
  • 51. Stomp • Stochastic Trajectory Optimization Planner • Optimization-based planner that generates smooth well behaved collision free motion paths in reasonable time. • Original work by (Mrinal Kalakrishnan, Sachin Chitta, Evangelos Theodorou, Peter Pastor, Stefan Schaal, ICRA 2011) • Code base was discontinued after the transition to ROS-hydro more than 2 years ago • Relevant moveit modules (now in moveit_experimental) were also discontinued
  • 52. STOMP highlights • Generates smooth well behaved motion plans in reasonable time, no need for post-processing smoothing. • Can Incorporates additional objective functions such as torque limits, energy and tool constraints. • Handles cost functions that don’t need to be differentiable. • Uses distance field and spherical approximations to quickly compute distance queries and collision costs.
  • 53. Current Status • Updated the deprecated STOMP code base so that it uses the latest in the MoveIt library. • Available as a Motion Planning Plugin that can be loaded by the move_group node and invoked from the rviz Motion Planning panel. • Can be easily configured with yaml files. • Loads robot and environment information from urdf, srdf and yaml files. • Optimizes for obstacle avoidance and smoothness. • Code available at https://github.com/ros- industrial/industrial_moveit
  • 54. STOMP Demonstration Videos • Moveit Planners vs STOMP • STOMP Demonstration
  • 55. Future Tentative Work • Allow for optimization of other relevant objectives such as dynamics, energy, path constraints, etc. • Remove residual dead code (a lot of work). • Better integration with the MoveIt pipeline (MoveIt Setup Assistant?) • Serialization of Distance fields generated from large models. • Handling of dynamic environment obstacles such as octomap and attached bodies.
