Mixing Body Parts between ERS-210 and ERS-220


Currently there are two models of AIBO that have interchangable body parts, the ERS-210 (Lion) and the ERS-220 (Cylon).

If you wish to swap body parts, the main body brick must contain the newer firmware. Use the body brick that came with the ERS-220. In future you will be able to update the firmware with the ERS-210 to 220 conversion kit.


Legs

The legs are not completely interchangable, since the physical shapes are different. You must match the front and back legs on each side of AIBO (ie. a 210 right front leg will not mesh with a 220 right hind leg).
Here are the combinations that work:


Head/Tail

The head and tail combinations are also limited by the physical shapes of the parts. Notably the 220 head unit won't work with the 210 tail.
Here are the combinations that work:


Combinations

Combining the two gives a total of 9 different combinations (or 12 if you consider the two different ways of mixing legs).
