Robot Foot are cybernetic members of the Foot Clan which appear exclusively in Teenage Mutant Ninja Turtles III: The Manhattan Project. They are noted to be similar in appearance to Fugitoid, specifically his 1990 action figure.
These robots appear in the Technodrome and Krang's spaceship. They jump around, especially when the player attempts to jump kick them, and wield handguns, which they can do when standing, jumping, or crouching. They can take much more punishment than the rest of the game's non-boss enemies, and even though they take damage from it, they can land from an overhead throw instead of hitting prone on the ground.
Their name is only found in an issue of Nintendo Power covering the game. Considering that the guide also mistook the Stone Warriors for variations of Foot Soldier, it is unknown if these are actually called "Robot Foot" or not according to Konami.
