Technologies for transportation

1. An apparatus comprising:

a platform;

a plurality of trucks coupled to the platform, wherein each of the trucks includes a wheel;

a roller assembly coupled to the platform, wherein the roller assembly is configured for an omnidirectional rotation about a first axis, wherein the roller assembly is driven by a motor, wherein the roller assembly includes a roller rotating about a second axis, wherein the first axis is distinct from the second axis, wherein the roller assembly comprises the motor, wherein the roller assembly comprises a roller, wherein the roller extends along the motor circumferentially; and a slip ring which conducts power to the motor.

2. The apparatus of claim 1 , wherein the roller assembly comprises an axle, a stator, and a rotor, wherein the motor comprises the stator and the rotor, wherein the axle is coupled to the stator such that the rotor rotates about the axle.

3. The apparatus of claim 1 , further comprising:

a battery configured to power the motor; and

a photovoltaic cell configured to charge the battery.

4. The apparatus of claim 1 , wherein the roller assembly comprises a plurality of mounts, wherein the roller is positioned between at least two of the mounts.

5. The apparatus of claim 4 , wherein the motor is positioned between the at least two of the mounts.

6. The apparatus of claim 1 , wherein the platform is defined via a first platform segment and a second platform segment, wherein the first segment comprises a first circuit portion, wherein the second segment comprises a second circuit portion, wherein the first circuit portion and the second circuit portion form a circuit based on the first segment and the second segment mating with each other, wherein the circuit facilitates powering of the motor.
