Autonomous Control for Electric Skateboards

Electronic differential speed control for electric skateboards that improves efficiency and range compared to mechanical differentials. The skateboard has separate left and right motor controllers. When the skateboard turns, the skateboard speed controller calculates the required differential wheel speeds based on physics. It sends these speeds to the left and right motor controllers, which adjust the torque. This simulates a mechanical differential without mechanical parts, reducing power consumption and extending range.

Electric skateboard with improved pose detection accuracy and safety. The skateboard has a simple and robust pose detection system using an inertial measurement unit (IMU) mounted on the skateboard body.

Controlling an electric skateboard using brain waves instead of a handheld remote control. A head-mounted brain wave sensor with dry electrodes detects electrical activity in the user's brain. The sensor sends the brain wave data to the skateboard's central controller which interprets the signals to control the skateboard's speed and movement. This allows hands-free operation of the skateboard without needing to hold a separate remote.

Skateboard with improved turning radius and stability using tilt control. The skateboard has at least one universal wheel and two driving wheels. A gyroscope senses platform tilt and generates a drive signal to control the speeds of the driving wheels differently to turn the board. This compensates for the large turning radius of existing rodless electric skateboards. The universal wheel follows the platform tilt. A controller receives tilt data, generates the drive signal, and coordinates with the pedal buttons. The skateboard can also compensate for slope using pressure sensors. Telescopic pedals adjust size for different riders.

Electric skateboard with weight-based speed control that increases safety by automatically adjusting speed based on rider weight. The board has weight sensors at the front to measure rider weight. If the weight exceeds a predetermined reference value, the control unit increases the rear wheel speed. This prevents oversteering and provides stability for heavier riders. The reference weight is set by averaging weight measurements over a period after the rider mounts.
