I would think that, judging by the E3 cutscene where it was dropped off of a dropship, that it is an autonomous drone. This is because, during the sequence, the Walker seemed to "let go" of a bar on the dropship's underside and drop down, landing on it legs and with weapons aimed in a defensive posture, similar to the fashion of Elites disembarking from a Spirit in Halo: Combat Evolved and Halo: Reach. When on the ground, much like Hunters in Halo, it immediately spread out it legs and charged th large cannon on its back, similar to a Hunter's Assault Cannon. This, and the lack of hatches, along with a "head" with camera-like "eyes" show that it may be remotely controlled as well.
