Can someone give me some guidance over the making of the ramp? What materials should I use, where can I get them, anything I should watch for etc.
Also, what do you do to make a seamless transition from the ramp to the floor? (so the vehicle exits the ramp smoothly).
Thanks in advance!
To get the most seamless transition from the ramp to the floor, I think it would be best to have the least possible exit angle. This would ensure that as much energy is converted from potential to kinetic as possible without any being lost in a non-smooth transition. For vehicle materials, it all depends on the tools you have available to you. For the supports, wood will likely be the most popular material because of how easy it is to work with compared to other materials, but plastic and metal can be used as well. For the ramp surface, you can use formica, sheet metal, thin plastic sheets, thin plywood, etc. You want the surface and the wheels to have a high enough friction that the wheels turn immediately upon release but not so high that it slows the vehicle down considerably. Sorry if this wasn't a direct response, but the materials you can use depend on your design and the resources you have available to you.
