First build the tracked base as shown.
Then you can add more K'NEX parts to it in any way you like, to create your very own tracked vehicle.

The model can be built using:
1. A K'NEX Base kit
2. 56 x K'NEX Chain link Small 20mm
3. 4 x K'NEX Sprocket gear Black
Items 2 and 3 above are used in almost all chain-driven K'NEX roller coaster sets.
Then create the front axle by adding to a red rod:
1. A tan clip with the pin pointing towards the end of the rod.
2. A blue spacer.
3. A yellow connector (with the rod through the hole in the middle).
4. Two blue spacers.
5. A white connector.
6. The motor.
7. A white connector.
8. Two blue spacers.
9. A yellow connector (with the rod through the hole in the middle).
10. A blue spacer.
11. A tan clip with the pin pointing towards the end of the rod.
Next:
1. Add a gear wheel onto each end of the rod, so that it engages with the pin on the tan clip.
2. Secure each gear wheel in place with a snap cap black.
Now assemble the rear axle by adding to a red rod:
1. A snap cap black.
2. A gear wheel.
3. A silver spacer.
4. A yellow connector, end-on to the rod.
5. Two blue spacers.
6. A yellow connector.
7. Two blue spacers.
8. Two silver spacers.
9. Two blue spacers.
10. A yellow connector, end-on to the rod.
11. Two blue spacers.
12. A yellow connector.
13. A silver spacer.
14. A gear wheel.
15. A snap cap black.
…loop each one over a pair of gear wheels, and join.
Your tracked vehicle base is now complete.
What next?
Test your vehicle base. You will find it runs best on a slightly rough surface such as a carpet, and it will climb over small objects such as a pencil.
Now you can add to the vehicle base in any way that you like, to make a complete vehicle to your own design. There are many different types of tracked vehicle you might consider, including tractors, snowploughs, bulldozers, and cranes.
Why not start by adding some rods to the yellow and/or white connectors in your model?
