2. The system of claim 1 , wherein the processing apparatus comprises a receiver configured to receive the signal derived from the sensor.

3. The system of claim 2 , wherein the receiver is a wireless receiver configured to wirelessly receive the signal derived from the sensor.

4. The system of claim 1 , wherein the tracked undercarriage comprises a drive wheel for driving the track and the sensor is configured to sense an interaction between the track and the drive wheel.

5. The system of claim 4 , wherein the interaction between the track and the drive wheel is slippage between the track and the drive wheel.

6. The system of claim 4 , wherein the interaction between the track and the drive wheel is a force between the track and the drive wheel.

7. The system of claim 1 , wherein the sensor is a wireless sensor.

8. The system of claim 1 , wherein the sensor is an optical sensor.

9. The system of claim 1 , wherein the sensor is a strain sensor.

10. The system of claim 1 , wherein the action controlling the vehicle is an action controlling the tracked undercarriage.

11. The system of claim 10 , wherein the action controlling the tracked undercarriage is an action controlling power applied to the tracked undercarriage.

12. The system of claim 11 , wherein the tracked undercarriage comprises a drive wheel for driving the track and the action controlling power applied to the tracked undercarriage is an action controlling power applied to the drive wheel.

13. The system of claim 1 , wherein the tracked undercarriage is configured to drive the track in a plurality of drive modes that includes a friction drive mode and a positive drive mode, and the action controlling the tracked undercarriage is an action controlling in which of the drive modes the track is driven.

14. The system of 38 , wherein the tracked undercarriage comprises a tensioner for tensioning the track and the action controlling the tracked undercarriage is an action controlling the tensioner.

15. The system of claim 1 , wherein the action controlling the vehicle is issuance of a control signal to a component of the vehicle to control the component of the vehicle.

16. The system of claim 15 , wherein the component of the vehicle is the tracked undercarriage.

17. The system of claim 1 , wherein the sensor is located inside the track.

18. The system of claim 1 , wherein the sensor is disposed within elastomeric material of the track.

19. The system of claim 1 , wherein: the track comprises a ground-engaging outer surface, an inner surface opposite to the ground-engaging outer surface, and a plurality of projections projecting from the ground-engaging outer surface and the inner surface; and at least part of the sensor is located between the ground-engaging outer surface and the inner surface.

20. The system of claim 1 , wherein: the track comprises a ground-engaging outer surface, an inner surface opposite to the ground-engaging outer surface, and a plurality of projections projecting from the ground-engaging outer surface and the inner surface; and at least part of the sensor is located in a given one of the projections.

21. The system of claim 20 , wherein: the projections include traction projections projecting from the ground-engaging outer surface and wheel-contacting projections projecting from the inner surface; and the given one of the projections is a given one of the wheel-contacting projections.

22. The system of claim 21 , wherein: the wheel-contacting projections include drive projections configured to engage a drive wheel for driving the track; and the given one of the wheel-contacting projections is a given one of the drive projections.

23. The system of claim 1 , wherein the sensor is a first sensor, the system comprises a second sensor configured to be part of the track and monitor the tracked undercarriage, and the processing apparatus is configured to process the signal derived from the first sensor and a signal derived from the second sensor to perform the action controlling the vehicle.

24. A machine-readable storage medium storing software for controlling a vehicle that comprises a tracked undercarriage for traction of the vehicle, the tracked undercarriage comprising a track for engaging the ground, wherein the software, when executed by a processing entity, causes the processing entity to:
receive data derived from a sensor that is part of the track and configured to monitor the tracked undercarriage; and
process the data to perform an action controlling the vehicle.

25. A tracked undercarriage for traction of a vehicle, the tracked undercarriage comprising:
a track for engaging the ground, the track comprising a sensor; and
a track-engaging assembly for driving and guiding the track around the track-engaging assembly.

26. A track for traction of a vehicle, the track comprising:
a ground-engaging outer surface for engaging the ground;
an inner surface opposite to the ground-engaging outer surface; and
a sensor disposed within elastomeric material of the track.

27. The track of claim 26 , wherein the sensor is located inside the track.
