1 Physical programs such as running, brachiation, gymnastics, and ballet.

2 If you consider brachiation, flight, and swimming from a broader evolutionary view, most animals rely on their "arms", from birds to whales to sea lions to fish.

3 With dynamical servo control theory introduced, life-like brachiation control of underactuated two-link robot is studied.

4 A dynamical servo control strategy was proposed to control the terminal of an underactuated 2-link robot to track a given trajectory or an object during its brachiation.

5 This intensive daily program included oxygen enrichment, crawling, creeping, running, brachiation, a gravity free environment, laterality activities, an intellectual program, and excellent nutrition.
