A vehicle capable of multiple varieties of locomotion having a main body; a plurality of motors and blades providing flying capability; each motor being associated with and powering a blade assembly; two legs extending from opposing sides of the main body creating a ground propulsion system. The ground propulsion system having two legs; each leg connected to a track body at the opposing leg end; each track body comprised of a plurality of drive gears; each track body connected to and retaining a track providing ground propulsion. The vehicle can either drive or fly based on its base structure, in additional to carrying a payload. The payload is carried below the main body of the vehicle and between the tracks or running gear. When the vehicle is in flight, the tracks are able to rotate up into a fly/flight mode to protect the blades during flight.

A system and method for automatically adjusting the tension of a track on a snow machine, or other track-driven vehicle, is disclosed. The system includes an axle mounted in slotted adjustment holes with an axle bolt or other means to fix the axle to the track guide of the track-driven machine. The system also includes one or more biasing members to exert a force on the axle. When an axle bolt is loosened, the axle moves forward or backward in the adjustment slots to achieve the proper tension on the track. The axle bolt can then be tightened to fix the location of the axle in the adjustment slots at the location that provides proper tension for the track. The system obviates the need to use complicated tools and procedures to properly tension the track.

A caterpillar device includes: a water film removing part which is provided in a power transmission member including chains, presses and removes a water film between an attachment object as a magnetic material, and the power transmission member with a magnetic force, and attaches the power transmission member to the attachment object to secure a frictional force; and an apparatus body magnet attachment part which is connected to the power transmission member and attaches the body of the apparatus to the attachment object.
