Abstract
A system configured to be mounted to a vehicle including a skid-based steering system. The system including a control unit for determining course correction to the vehicle during operation based on a navigation path received from a remote device and data associated with the movement of the vehicle collected by the system.
Claims20
A vehicle comprising:
- a left propulsion device to propel a left side of the vehicle at a first velocity in a first direction;
- a right propulsion device to propel a right side of the vehicle at a second velocity in a second direction;
- a skid-based steering system, the skid-based steering system including a left drive motor to drive the left propulsion device and a right drive motor to drive the right propulsion device;
- a control system electrically coupled to the skid-based steering system, the control system to send a command to the skid-based steering system, the command to cause the skid-based steering system to propel the vehicle in a desired manner, the control system including:
- a wireless communication interface to receive a navigation path from a remote device;
- an angle acquisition unit to collect data associated with a movement of the vehicle and rotational angular rates of the vehicle;
- a positioning unit to collect data associated with a global position of the vehicle;
- and
- a control unit to determine attributes of the command based at least in part on the navigation path, the data associated with the movement of the vehicle, the data associated with the rotational angular rates of the vehicle, the data associated with the global position of the vehicle.
