In cognitive robotics "ongoing development" refers to the ability to continuously build on what the system already knows, in an ongoing process, which acquires new skills and knowledge, and achieves more sophisticated levels of behavior. Human infants are possibly the best known demonstrators of this ability; developmental psychology has many results documenting what infants can and cannot do at various ages, however we know very little about the mechanisms underlying the development. On the robotics side, creating a computational system which displays ongoing development is still an unsolved problem. There are major unsolved questions regarding the mechanisms of ongoing development, in both biological and artificial systems; for example: how to transfer existing skills to a new context, how to build on existing skills, and how to represent knowledge (or skills).
The primary aim of the seminar is to bring together researchers from two communities (developmental robotics and infant developmental psychology) in order to spawn new collaborative research projects which will advance our scientific under- standing of the mechanisms underlying ongoing development (whether in infants or robots).
In order to achieve a greater depth in discussions, and to keep a concrete real-world focus, we intend to narrow the focus of the seminar somewhat: we will especially focus on perception, understanding and manipulation skills relating to physical objects in the world, and the skills which infants acquire in approximately the 4-24 months period. This period begins with infants executing actions on single objects (banging, scratching, squeezing), and ends with infants executing accommodative relational acts on object combinations, for example placing a peg in a hole, stacking blocks, standing a cylinder on its end, placing a lid on a jar, using a long stick or hook to retrieve a distant object, transporting food on a spoon. Infants at the end of this period have quite a robust repertoire of skills for manipulating physical objects, which is the result of a long developmental trajectory exhibiting ongoing developments which build on each other.
The following are core questions which will be discussed in this seminar:
- How is a state-space explored? Given a scenario with a certain number of degrees of Freedom (DOFs), how does the infant go about varying parameters (e.g. at low level of motor control, and high level of spatial relationships among objects)?
- What is the infant motivated to explore, and in what circumstances do they give up? (Giving up also tells us something about the intrinsic motivation.)
- How do infants learn new skills? (For example, one method could be by scaf-folding.)
- How do infants add these new skills to their motor repertoire?
- How is old knowledge transferred or re-used? Where do we see infants borrowing old sensorimotor routines; how do they adjust them to the new situation?
- How robust is the behavior? In other words, to what similar situations does the infant easily generalize (meaning they start to develop the beginning of abstract representations and concepts), and to what situations does she fail to generalize?
- What representation of objects, spatial relationships, actions, and effects might be in use?
Significant advances can be made on these questions if the appropriate experiments are carried out, but such experiments may be unlikely to be performed without interaction between psychologists and computer scientists.

We especially focused on perception, understanding and manipulation skills relating to physical objects in the world, and the skills which infants acquire in approximately the 4-24 months period.
Working groups were formed in the areas of (i) transfer of means/skills; (ii) motor skills/manipulation; (iii) concepts/representations; (iv) motivation; (v) visual perception. These discussed gaps between what infants and robots can do and what research might close the gap. In discussion groups the most significant issue that was raised (and discussed at length) was how to get psychologists and roboticists talking together and doing research together, as there seems to exist a wide gap between the communities. It was concluded that there was a need for psychologists to become computer scientists and computer scientists to become psychologists; i.e. that the meeting of the two fields would not happen simply by people getting together in a room, but that the meeting must happen inside individual heads. Furthermore challenge problems were posed by each of the two respective communities; challenges which they would like the other community to work on.
