3. High Level Device Operation
The user/rider has to interact with the skateboard, remote, mobile application and charger. The detailed description on
working of each part is presented in the coming sections. But before that, let us discuss the high level operation of
GoBoard B2. The skateboard is powered on by pressing the power button on the skateboard. The skateboard should
always be powered after putting it on the ground and there should not be any weight on the skateboard. The skateboard
can be connected to mobile application at any instant of time once the skateboard has been powered on. When the
skateboard is powered on, the buzzer beeps once which shows a normal start up. But if the buzzer beeps twice soon
after powered on, it indicates the last shutdown was not normal (see section 4.3 for details). There are two modes of
operation i.e. remote control and body control.
3.1 Remote Control Mode
When the skateboard and remote are powered on and remote is connected to skateboard, the skateboard enters in the
remote control mode. The throttle stick on the remote is used to accelerate and brake. For details, see the upcoming
sections.
3.2 Balance Control Mode
When the skateboard is powered on and remote is disconnected to skateboard, the skateboard enters in the body control
mode. After getting on the device (see the below section), lean on left/right foot to accelerate and lean in opposite
direction to brake.
3.2.1 Getting on Skateboard in Balance Mode
Getting on skateboard in balance mode is a bit tricky. Put the skateboard on the perfectly flat ground and skateboard
should be static. Now first put your left/right foot on the respective corner of the skateboard and within a second put the
other foot on the other corner. The skateboard speed be zero in the process. Keep the distance between the legs as much
as you can. Once the rider has got on the device, the skateboard intimates the user by playing an alarming sound. If the
rider doesn’t hear the alarm, there could be two reasons i.e. the weight sensors might not be calibrated or the getting on
sequence is not right.
