The Freeyoyo personal transporter is a dual-wheel self-balancing electric vehicle, a revolutionary ride-instead-of-walk and recreational tool. The driver may operate the movement of Freeyoyo by standing on it, and shifting his/her body. The Freeyoyo itself may automatically keep balance and the driver does not have to worry about the risk of falling down.With the built-in electronic gyro, the on-board high speed CPU may calculate 200 times/s, checking whether the Freeyoyo is in balance situation. If not, the CPU may control the motor on both left and right sides to rotate rapidly, and keeping the Freeyoyo balanced. Due to the self-balancing function, the driver may make the wheels move forward by inclining his/her body forward; and vice versa. Also they can turn left or right simply by turning the handle accordingly.As the balance of Freeyoyo completely depends on the good functioning of high speed CPU, precision gyro and motor, any malfunction of them, the Freeyoyo may lose balance. The Freeyoyo has a hot back-up dual-redundant control system which ensures that all key circuit systems had been doubled. Therefore, if any one of the key modules fails to work, the backup may be put into function so as to maximize the safe riding.Freeyoyo is looking forward to closer cooperation with friends from all over the world.
