Details: I've previously blogged a few interesting walking machines here, but the fact of the matter is that many of those models are a bit out of reach for most LEGO fans. The availability of various parts (specifically motors and pneumatic elements) leaves a bit to be desired. However, there's one current kit (the 8049 TECHNIC Log Loader) that is widely available and actually includes all the parts you need to try out simple pneumatic circuitry and walking machines. Naturally, I took this as a challenge - can a decent pneumatic walker be built out of only the parts in that one kit? You can see the results (and full building instructions!) at the links above. Spoiler alert: it can be done, but it took me a few tries to get it working smoothly.
