2015 has seen a spread of alternative powered vehicles released for personal transportation. Most of these are a variation on the powered unicycle:
* The Ryno Electric Unicycle which is basically half a motorcycle for possibly around $3,500
* Self Balancing Electric Unicycle Scooter such as the 'airwheel X3' for around $300 to $1,500
* Skateboards with one huge wheel
* Two Wheel Self-Balancing Scooter for $500 to $1200
* and the powered unicycle has been around for a while
* Powered skateboards like this have also been around for a while
* with the Caseboard making the powered skateboard that folds into a suitcase

We've seen Monowheels before with more emphasis this year being seen on single wheel powered devices.

A basic hoverboard has been invented, but it only works on a specific surface, so we are still waiting for Marty McFly's hoverboard. So, these are our options for now and they can only get cheaper and better. In terms of personal transport options 2016 is looking good.

Combining biological components, such as cells and tissues, with soft robotics can enable the fabrication of biological machines with the ability to sense, process signals, and produce force. Engineers at the University of Illinois are working on developing a Bio-Robot which can be produced easily by using 3D printing technology. They developed similar bio-bots few years back, but that time they used heart cells. Now they find a way to use muscle cells to gain more control. The frequency of the electric field determines the speed of this bio-bot.
