Powered wheelchairs are often too bulky to fit under a standard table, yet this is critical for social interaction (i.e., in a restaurant, at home, or at work). Pilots should be able to drive close to a table in such a way that the thighs of the pilot fit below the tabletop.

In this task, the pilots have to navigate their wheelchairs so that half of their thighs are placed under a table without moving any furniture.

Paths in nature are often uneven and rough. Powered wheelchairs must be able to cope with such terrain such that their users are not restricted during recreational outdoor activities.

In this task, pilots and their assistive devices are challenged to navigate a stony path with their wheelchairs.

Often in daily life, it is necessary to navigate around static or moving obstacles to reach a desired destination. When moving in dynamic crowds, in particular, constant control of direction and speed is required to avoid collisions.

In this task, pilots must pass between individual pieces of furniture. In addition, collisions with several robots that are roaming the task space must be avoided.

Small items that are randomly lying around (e.g., a child’s toys) can obstruct a wheelchair user’s path. He or she might want to pick up the objects to either use them or stow them away.

In this task, the pilots must pick up a bottle from the floor and place it on a table.
