Indoor Navigation

Concept

• As a map representation, we proposed a hybrid map using object-spatial layout-route information.
• Our global localization is based on object recognition and its pose relationship, and the local localization uses 2D-contour matching by 2D laser scanning data.
• Our map representation is like this:

• The Object-based global localization is as follows:

Unknown Objects Grasping

Concept

• With a stereo vision(passive 3D sensor) and a Jaw-type hand, we studied a method for any unknown object grasping.
• In the context of perception with only one-shot 3D image, three graspable directions such as lift-up, side and frontal direction are suggested, and an affordance-based grasp, handle graspable, is also proposed.

• Our grasp directions are as follows:

• The schema of our whole grasping process is like this:
