Parallel parking. This is one of the tests you have to do to get a class A license. You have to get the trailer centered in the cones.
ally dock. This is another test for a class A license. you must back up and center the back of the trailer in the cones
here is a diagram that explains how the steering works. the truck is much more maneuverable with trailer steering than without.
this is my latest semi. It is of my own design, but was inspired by a scania R620. I decided to build a smaller truck for a couple reasons. First the DAF it was built from was too heavy to drive on carpet (it weighed just over 8 pounds), and second because it was so heavy, it ate up batteries very fast. it is driven by an XL motor, with tandem drive axles. The steering is done with a medium motor, and there is also a steering axle on the trailer. The trailer is dumped with a linear actuator and a medium motor. This is one of the few vehicles I have made that doesn't have doors and an interior. The cab of the truck is filled with all the electronics so there was no room. It was quite a challenge to fit an XL motor, an M motor, the battery box and receiver in such a small space, along with the steering and drive train. It was also a challenge to get the motor, actuator and traler steering linkage in such a small space too. This truck was as small as I could get it with the technical features it has. later I will post videos of it preforming the same tests That I had to do to get my class A license (license to drive a semi truck) so if anyone has ever wondered yes I do know how to drive an actual semi, in fact that's what got me hooked on building them was when I was in trucking school.
