The core tech of FOSJOAS powered self-balancing scooter aerospace attitude control theory

It is well-known that FOSJOAS self-balancing scooter adopts one technology called aerospace attitude control theory. But few people know about this technology and who it works in FOSJOAS self-balancing scooter. 

Attitude control is controlling the orientation of an object with respect to an inertial frame of reference or another entity.

Controlling vehicle attitude requires sensors to measure vehicle orientation, actuators to apply the torques needed to re-orient the vehicle to a desired attitude, and algorithms to command the actuators based on sensor measurements of the current attitude and specification of a desired attitude. The integrated field that studies the combination of sensors, actuators and algorithms is called “Guidance, Navigation and Control”. 

A spacecraft’s attitude must typically be stabilized and controlled for a variety of reasons. It is oftentimes needed so that the spacecraft high-gain antenna may be accurately pointed to Earth for communications, so that onboard experiments may accomplish precise pointing for accurate collection and subsequent interpretation of data, so that the heating and cooling effects of sunlight and shadow may be used intelligently for thermal control, and also for guidance: short propulsive maneuvers must be executed in the right direction.

There are advantages and disadvantages to both spin stabilization and three-axis stabilization. Spin-stabilized craft provide a continuous sweeping motion that is desirable for fields and particles instruments, as well as some optical scanning instruments, but they may require complicated systems to de-spin antennas or optical instruments that must be pointed at targets for science observations or communications with Earth. Reaction wheels provide a much steadier spacecraft from which to make observations, but they add mass to the spacecraft, they have a limited mechanical lifetime, and they require frequent momentum desaturation maneuvers, which can perturb navigation solutions because of accelerations imparted by their use of thrusters. 

The advanced tech introduced in FOSJOAS electric scooter is called a breakthrough in the history of application of science and technology. If interested in it or FOSJOAS, please go to its website.
