Contributors: Aleksey Titov, Kayman, Pyo
0.4.1 (2016-09-05)
Added include files for footstep_planner and gridmap_2d for install.
uses double 2.0 and makes style locally consistent
catkinize the stack
Add service to (re)plan between feet as start and goal.
Requires newest humanoid_msgs.
Merge plan and replan functions
RViz launch file / config Groovy
mark heuristic as expired when map is updated
removed code in the destructor that gets already cleaned up in the super class
use pre-increment instead of post-increment (faster + post-increment for iterators not always optimizable)
fixed sbpl exception catch
introduced new functionality to totally reset the planning environment
storing environment params in new struct -- get rid of unnecessary member variables
more detailed information when sbpl planning was successful but only the old path is returned
wait 0.5 sec before updating the start (robot) pose
bug fix in path cost heuristic
make footsteps smaller; + std::max
handle receiving of foot transformations differently
implemented the polygon-intersection-check for the navigation as well; not used so far due to some usability issues
bug resolved: free the execution log when planning failed; use ros::Time(0) instead of ros::Time::now() since when using the latter sometimes the tf cannot be received (now sometimes an outdated step is received but this works better anyhow)
bug resulting in segfaulting thread now (probably) resolved
replaced old reachable check by a new more smoother grid based approach
small fix in the replanning logic
enforce planning from scratch when necessary (e.g. goal changed when using backward planning)
added assertion to enforce correct heuristic calculation
applied ROS code style
reorganized the way FootstepNavigation invokes the planner and starts the execution; changed FootstepPlanner::updateMap

0.4.0 (2013-01-10)
Updated stack.xml & CMakeLists, new version 0.4.0 to release
adjusted robot translation in z dir
footstep execution now aborted when map changes + replanning and new execution is started; again use ALL calculated steps when extracting the path
Changes in R* launch file params
using only the new launch file from pkg nao_driver
Fixed odometry lookup error (wrong frame)
Indenting / code style according to ROS style
fixed SBPL in CMakeListe for custom-installed location
fixed out of map check in R*
cleanup of R* code
manifest/CMakeLists now compatible with fuerte and electric compilation, includes should work better now
integrated the new footstep set
fix: spelling error (don't forget to update nao_driver and humanoid_nav_msgs)
navigation parameters in extra config file; using new launch file in nao_driver
handle situations where both start feet are part of the calculated solution
method rearrangement in the navigation
got rid of get_footstep in helper
added test to check whether all footsteps can be performed by the NAO robot; adjusted invalid footstep
now able to switch between protective and fast footstep execution via the 'protective_execution' param + various smaller changes
Finished fluid footstep execution for the NAO; has still to be tested for simulation/real robot
added footstep_planner_walls to read in separate wall map (larger clearing)
expanded states is now a hash map on x,y => vis.better in RVIZ, only one expanded state per (x,y)
heuristic_scale parameter to increase under-estimating heuristics
GetSuccsTo for improved R* functionality
nao_path_follower now accepts paths
Fixed PathCostHeuristic for non-square maps
reaching right goal foot faster, only left goal state absorbs now.
also show expanded states when failing; R* optimized (exact ==)
PathCostHeuristic is now inflated by foot incircle

0.3.1 (2012-06-15)
preparing for fuerte release and sbpl package
replanning based on old planning info in cases of a changed map disabled for now (instead: complete new planning in such a case)
approx. comparison for R*
footstep-feedback synchronization now handled in the action client (in FootstepNavigation.cpp)
cost calculation directly based on the discrete planning states
during the planning the reachability check is now based on the discrete position and orientation of the state (planning speed up)
temp. simplification of the path cost heuristic calculation
got rid of FootstepPlannerEnvironment::setUp - this is now done in the resp. updateGoal/updateStart-method (this makes it possible to reduce FootstepPlanner::run to its actual functionality)
Removed ANAPlanner (testing, requires newer SBPL)
Functions (stubs) added for R*
changed names of the robot feet (according to ROS standards); integrate actionlib to perform footsteps
corrected foot box for the nao robot
corrected footsteps (w.r.t the new step model and the old footstep sets)
footstep navigation debug and footstep execution debug update
some bugs affecting footstep execution fixed
footstep execution now completely discrete
new function for lengths (to distinct between grid cell discretization and length discretization; footstep calculation fully based on discrete footsteps (can be further optimized by calculating reverse footstep on the fly)
update of start pose in own function: used before planning and replanning
bugfix: set gready footstep
map callback subscription
add missing goal pose callback subscription
footstep robot navigation integration finished
replaced double-ptr returns with references in get_footstep() / getFootstep()
Added execution functions from old footstep planner code to FootstepNavigation
FootstepNavigation stub added
Contributors: Armin Hornung, Johannes Garimort
0.2.0 (2011-11-28)
automatic replanning after map change
reset planner when to many states changed after map change
2nd changed sample map added
inserted stubs for R* env. functions.
using old information in replanning after map change
fixed invalid states appearing on border of map during expansion
fixed corner cases for angles heuristic
added foundation for map change detection
get rid of last continuous planning state variable
orientation cost
fix on path cost heuristic and the recalculation w.r.t correct search direction
path cost heuristic implementation finished
footstep_planner now uses SBPL instead of D* lite, enabling ARA* and AD* for search with anytime capabilities
