Autonomous gladhands coupling systems, devices, and methods

A system comprising:

• (a) a vehicle comprising a pneumatic source of pressurized air;
• (b) a first arm assembly comprising:
• (i) at least one axially-extendable arm having a first end coupled to the vehicle and a second end opposite the first end along an axial direction of the arm;
• (ii) at least one linear actuator coupled to the at least one axially-extendable arm;
• and
• (iii) a first end effector releasably coupled proximal to the second end of the at least one axially-extendable arm, the first end effector comprising a gladhand coupling portion configured to be coupled to a gladhand receptacle of a trailer;
• (c) first and second cable portions extending between the vehicle and a distal portion of the first arm assembly;
• (d) at least one cable actuator configured to independently change respective lengths of the first and second cable portions between the vehicle and the distal portion of the first arm assembly;
• and
• (e) an air supply line coupled to the vehicle and the first end effector, the air supply line being configured to deliver pressurized air from the pneumatic source to a braking system of the trailer when the gladhand coupling portion is coupled to the gladhand receptacle.
