With the freshly cut delrin, we loosely assembled the head frame and the trunk.
Below, the tubing runs through the trunk and into the base of the body. We chose to omit the body box because a cloth skin will later cover the entire elephant. Each tube will be connected to its distinct pump.
Long beams were reluctantly attached to prevent unlikely tilting of the elephant and lawsuits from parents of supposedly injured children. The casters were then secured underneath the beams.
The trunk curls as the center handle is pulled, which creates tension in the fishing line and bends the plastic.
The one-way valves can be seen above. Both pumps connect to the reservoir, which holds the water that was pumped in.
Phroomie is born!
Unlike most transporters, our elephant was not powered by servos and was designed on a far larger scale. Of course the project went over budget (by about $11), but it is because the kit provided was not suitable for projects its size. The purpose for this design is to maximize interactivity of the toy with the child. With a remote controller, a child is limited to the amount of rotations the motors can turn. But a child can physically touch, climb, and move Phroomie, which enhances the play experience.
