How to Teledrive a Modded RC Car (Drive from anywhere around the world)

1. How to remotely drive a vehicle from anywhere in the world?
2. Teledrive ie remote drive is a useful idea.
3. One application: UAVs are flown around the world for surveillance while sitting in the comfort of a terrestrial ground station.
4. Another example is to drive a Truck over the network like here: Einride Remote Drive Prototype 
5. Customising a commercial EV even though a very exciting exercise has its own challenges and timelines.
1. Need to understand the mechanical angle and also the hardware angle, say identify relevant motors, torques and install and check they perform optimally. Will have to be iterated multiple times.
6. A better option would be to try all the experiments on a small scale, say on a toy. Something similar to the Flight of Phoenix (2004) movie.
7. There have been many mods of expensive RC car like the Traxxas car. Traxxas RC cars
1. But these are expensive and hence a low cost solution is needed
8.  There are many Off the Shelf RC cars. But they are usually very small and cannot be driven on the roads.
9. Was lucky to find a large RC car about 2 feet in length.
1. It came with all the fitments: battery compartment, shocks, Ackerman steering mechanism ,etc The unmodded vehicle is as shown below
10. The new RC vehicle is low cost so car lifetime might vary.
1. The Remote control would get stuck and this would have its own challenges.
11. This vehicle is pretty fast as it has 2 motors, 1 each for back and front and an additional one for the steering. The Steering motor does not have fine control. It also has a set of lights but they were not very useful in the dark.
12. The vehicle was modded and stripped down to the chassis. 
1. Motor drives for the 3 motors were added.
2. A RPI for drive control and also for streaming camera feed. Standard RPI camera.
3. An Airtel 4G SIM with a Quectel modem module.
4. A drone LiPo battery with voltage regulators.
5. An IP 65 box was used to house all the hardware   
13. And the result:

• Now need night driving support too 
• Added a bicycle light on the chassis as follows
  
  
  
  
  
  

Driving

• The video and control path from the Modded Car is accessible at an AWS location.
• One can connect from anywhere in the world and drive the car. Attached below is the video of it being driven remotely. The  FPV and the rearview
