Ground vehicle

A system of vehicles comprising:

• a first ground vehicle comprising:
• a platform;
• a first swing arm assembly rotatably coupled to a first side of the platform and comprising a proximal end of the first swing arm assembly and a distal end of the first swing arm assembly, the first swing arm assembly configured to:
• move from a first position of the first swing arm assembly to a second position of the first swing arm assembly by rotating the first swing arm assembly about a first pivot point on the first side of the platform, the first pivot point corresponding to where the proximal end of the first swing arm assembly couples to the first side of the platform;
• and
• move from either the first position of the first swing arm assembly or the second position of the first swing arm assembly to a third position of the first swing arm assembly by actuating the first swing arm assembly from the first pivot point such that the distal end of the first swing arm assembly moves away from the platform to broaden a wheelbase of the ground vehicle;
• and
• a first centerless wheel assembly rotatably coupled to the distal end of the first swing arm assembly, the first centerless wheel assembly configured to roll along a surface and maintain a first vertical orientation to the surface in the first position of the first swing arm assembly, the second position of the first swing arm assembly, and the third position of the first swing arm assembly;
• and
• a second vehicle;
• wherein the first ground vehicle and the second vehicle are communicatively coupled.
