In BEAM robotics, a Crawler is a robot that has a mode of locomotion by tracks or by transferring the robot's body on limbs or appendages. These do not drag parts of their body on the ground.
- Turbots : Rolls over and over as a mode of locomotion via arms or flagella.
- Inchworms : Driven mode of locomotion via the robot's body undulating; this undulation moves part of the body ahead, while the rest of the chassis is on the ground.
- Tracked robots : "Track-ed" wheel locomotion; tank-like action.
