1. A personal transport vehicle comprising:
- a first wheel and a second wheel;
a first motor configured to drive the first wheel;
a second motor configured to drive the second wheel;
at least one platform for supporting a driver;
a plurality of pressure sensors configured to detect pressure applied by the driver on the platform; and
a control circuit coupled to the plurality of pressure sensors and configured to determine a pressure differential across the plurality of pressure sensors;
wherein the pressure differential compares the pressure detected in a first footpad and in a second footpad, the control circuit generates, based on the pressure differential, control signals for the first motor and the second motor to drive the first wheel and the second wheel to turn the vehicle.

Abstract
A personal transport vehicle may include a first wheel and a second wheel, a first motor configured to drive the first wheel, and a second motor configured to drive the second wheel. The vehicle may also include at least one platform for supporting a driver, a plurality of pressure sensors to detect pressure applied by the driver on the platform, and a control circuit coupled to the plurality of pressure sensors to determine a pressure differential across the plurality of pressure sensors. The control circuit may generate, based on the pressure differential, control signals for the first motor and the second motor to drive the first wheel and the second wheel to turn the vehicle.
