[Summary by Kostas Bekris]
A large body of work at IROS related strongly to planning and control algorithms for robot motion. Thus, the following overview cannot be exhaustive but it attempts to highlight some of the challenges that the community, and especially the members of our committee, are trying to address with planning and control solutions.
Some of the papers focused on kinodynamic motion planning either by computing appropriate curves that directly satisfy dynamic constraints [1,2] or by studying how random linear projections of complex systems can be utilized to improve planning with dynamics . A paper focused on complementarity-based dynamic simulation algorithms, which are often used as local planners in sampling-based algorithms . The paper showed that complementarity-based solutions perform well in cluttered environments and are relatively insensitive to parameter choices. Such physically realistic simulation tools were also employed in order to solve disassembly problems  or in order to predict the appropriate actions by a real robot playing the game of Jenga .
Another focus area corresponded to collision-free motion coordination for multiple robots or agents. Previous work on velocity obstacles and reciprocal velocity obstacles was extended in order to account for constraints of car-like robots  and uncertainty in sensor data so as to avoid oscillations . Another work dealt with "group control problems", such as simulating the operation of a shepherd agent that guides flocks of robots through obstacle-filled environments . Other multi-agent works focused on pursuit-evasion problems. One paper dealt with the "lion and man" game in the presence of circular obstacles , while a different work introduced a simulation platform for studying such problems .
Many papers dealt with problems related to dynamic and/or uncertain environments and the need for anytime and real-time planning. A Bug-like algorithm for anytime planning was presented, which showed favorable performance in simulation . Another paper extended the RRT algorithm by explicitly considering the robot's mobility in uneven terrains and the resulting uncertainty . Other papers focused on manipulators. For example, one work dealt with the real-time computation of whether a manipulator's trajectory is collision-free without any minimum-distance calls . Moreover, Willow Garage's PR2 robot was employed to show how to integrate 3D perception with real-time replanning for personal robotics applications .
Motion planning specifically for manipulation was the focus of multiple sessions. A paper showed how planning using the best single hypothesis under pose uncertainty for the manipulator often fails and how it could be remedied by the proposed approach . A different paper dealt with pose uncertainty in the base of a mobile manipulator and proposed an approach based on the idea of Lazy-PRM . The focus of another paper was to utilize ideas from control in order to address task-constrained manipulation and planning problems for redundant, possibly nonholonomic systems . There were also manipulation papers that did not dealt with robotic arms. For example, one work presented a mechanism and a control strategy for non-contact manipulation of spherical objects in three dimensions using air-flow .
There were also multiple sessions devoted to humanoid robots and multi-arm systems, where many planning papers appeared. A paper decomposed a multi-arm system into parts and combined the results from different roadmap-based techniques for the overall solution . A method for generating humanoid whole-body motion derived purely as a result of moving the head joint was also presented at IROS . Other works focused on solving regrasping tasks for multi-arm systems  and controlling the internal forces and moments produced during multi-contact interactions between humanoid robots and the environment .
A series of planning papers dealt with challenges in medical robotics. For example, how to plan the motion of steerable medical needles  or active cannulas , medical devices composed of thin, pre-curved, telescoping tubes that may enable many new surgical procedures. Or, finally, how to automate a common surgical procedure of exposing an underlying area by grasping and lifting a thin layer of tissue .
