Found this on a walk in the woods in Thailand.  It is just like ours in the US, but MUCH bigger!  There has been some discussioni that this is not a rollie pollie, but rather a pill millipede.  I will include the information on that below as well.

From Wikipedia:
Armadillidiidae is a family of woodlice, a terrestrial crustacean group in the order Isopoda. Unlike members of other woodlouse families, members of this family can roll into a ball, an ability they share with the outwardly similar but unrelated pill millipedes and other animals. This ability gives woodlice in this family their common names of pill bugs,[1] roly polies, or doodle bugs.[2] The best known species in the family is Armadillidium vulgare, the common pill bug.

Ecology and behaviour
Roly poly bugs in the family Armadillidiidae are able to form their bodies into a ball shape, in a process known as conglobation. This behaviour is shared with pill millipedes (which are often confused with pill bugs[3]), armadillos, and cuckoo wasps.[4] It may be triggered by stimuli such as vibrations or pressure, and is a key defense against predation; it may also reduce respiratory water losses.[5]


======================
Pill Millipede: 
Pill millipedes are relatively short-bodied compared to most other millipedes, with only eleven to thirteen body segments,[2] and are capable of rolling into a ball when disturbed, as a defense against predators. This ability evolved separately in each of the two orders, making it a case of convergent evolution, rather than homology. They can also exude a noxious liquid, which may be both caustic and toxic, to repel predators.[3] Pill millipedes are detritivorous, feeding on decomposing plant matter, usually in woodlands.[4]
