Introduction
What is a Ninebot PTR?
The Ninebot Personal Transportation Robot (PTR) is a new form of
intelligent electric balancing vehicle. The rider can stand on the vehicle
to operate it by moving his/her body, or control it using a smart mobile
device. Ninebot boasts the following features:
1. Zero turning radius.
2. Rider controls the PTR with his/her body posture instead of an
accelerator or a brake, thus making it natural and comfortable
to ride.
Thanks to the PTR's precision posture sensor, the on-board high-speed
CPU ensures the vehicle is in balance in the forward and backward
direction at the rate of 200 times per second. If not, the CPU activates
both motors to quickly achieve balance. The Ninebot can balance itself automatically, so that if the rider stands on it and leans forward,
the wheels move forward—the wheels move backward if the rider leans back. The rider can also turn right and left simply by leaning
the steering bar in the corresponding direction.
Ninebot has a projected usage envelope similar to that of a person with high maneuverability, meaning it has access to most of the
places where walking is possible, including paths, sidewalks, corridors, rooms, and lifts/elevators. Thus, as a transportation device,
it lies somewhere in between driving a vehicle and walking. However, in terms of riding method and the places Ninebot can go, riding
Ninebot is more like walking than driving a vehicle. Ninebot is a great choice for you to go somewhere that is either too far for walking
or too near for driving a vehicle.
