Do you have to solder?

No. But keep in mind, this is just a platform and wheels. You will need to add a microprocessor, motor driver and sensors. If you mount a breadboard on is platform, you can probably get away without having to solder at all

is the chassis compatible with a Jetson Nano?

We have not tried it, but in fact it can be done, because the platform has many reserved drilling holes, or using brackets, both of which can be equipped with Jetson Nano.

what is the torque constant of the motors?

Motor torque: 0.8km/cm (high speed and medium torque)

How to change the heading direction of the car?

Make the wheels on one side go forward and the wheels on the other side go in reverse will cause the car to turn
