1.3 Description of Warning Signs
When reading this manual, please pay special attention to the following warning information:
Warning: The user's improper operation may cause injury
Note: Items and using methods requiring attention of the user
2. Product Introduction
2.1 Model Description
◆ The product you purchased is the Robstep M2 two-wheel electric human transporter with dynamic balance developed
and produced by Robstep. This product controls driving by the dynamic balancing principle, and controls the driving
speed and direction of Robstep M2 with the adjustment of human postures.
◆ Robstep M2 is the second generation of Robstep M1, has greatly improved experience, safety, appearance, etc., and
provides better driving experiences to the user.
◆ Robstep M2 is suitable for private trips, work inspection, indoor stadiums, tourism and entertainment, trips by car or
subway, etc., to facilitate the trips of the user.
2.2 Serial Number of Products
◆ Every Robstep M2 has a unique serial number, which is used for quality tracing, insurance claim and claim for missing.
Please retain the serial number.

◆ Method to acquire the serial number:
Acquire from the packing case or the SN registration card (please take care of the serial number after acquisition).
2.3 Principle of Operation
◆ Robstep M2 mainly comprises the transporter body, wheels and a circuit system.Wheels are installed on both sides of
the transporter body, and modules of the circuit system such as the power supply, a control circuit, a driving circuit,
sensors and a control switch are installed in the transporter body.The wheels and the transporter body are connected
by a rotary shaft, and a speed sensor, a gyroscope and an acceleration sensor transfer the rotary speed of wheels and
the posture information of the transporter body to the control circuit, for controlling the torque and the moving speed
of a motor to keep the balance of Robstep (Robstep M2 and the user). When the user stands on Robstep M2 correctly,
Robstep M2 can match well with their body, and a power device controls the wheels to move forward or backward to
keep balance when the body slightly inclines forward or backward.
◆ The handle has the function of controlling the transporter body to turn. When the handle turns, the transporter body
turns.
◆ The inertial dynamic balancing and stabilization system built in Robstep M2 can keep the balance of the
transporter body from front to back.However, the system cannot control the stable balance from left to right, so when the
driver turns, their center of gravity must incline toward the steering rod, to overcome the centrifugal force of steering and
