This is absolutely amazing. From designing to coding to assembling, everything has been single-handedly, hand-built. So many different areas of knowledge are required for something as "simple" as an RC-car with extra options. I hope I'm also able to get to this point one day. Imagine a fully scaled-up version of this with 4-wheel independent steering!

@thehardwareguy are you aware you can get servos with telemetry feedback? Would be interesting to log the telemetry data from the steering servos. e.g. FrSky XAct? I'm sure there's some interesting stuff that can be done there, including automatic end-point calibration.

@@thehardwareguy You might end up with something similar as a flight controller for a drone. That uses a PID loop to keep the craft in a certain angle until you change any of the axis. Is the board equipped with sensors like a gyro, magnetometer/digital compass and accelerometer? I think you will need a lot of feedback from the car to make it do what you have in mind. In any case I'm really looking forward to what you come up with, this sure has a lot of potential :-D.

That's really cool. The placement of the motors is really smart. Just one suggestion if you haven't think about it yet, now that you control everything through the MCU and coding it yourself, you can go with 4 wheel steering. On the hardware side you only need to have the same part that you have in front of the car, in the back.

One huge suggestion for added strength and reliability. Where alignment is critical, or you have motion, switch over to shoulder bolts. Think of it like a dowel pin that can apply a clamping force. I can see this being very useful to strengthen the joints where the parts of the body come together. Also, this would be very handy in just about every suspension joint, And on the suspension joints, consider adding a hole for injecting lubrication. Just a short M2 grub screw hole would be great. The screw would keep debris out of the hole during normal operation. When you inject lubrication into the hole, it would force out the old lubrication along with any contaminates picked up while in use. For the non-rotational parts of the suspension, consider a gel type silicon lubricant. It would stay in place and take up any slop to help reduce wear to the plastic. I've actually done this to my highly modded WLToys A959.

Have you considered doing 4 wheel steering? It seems like it would be easy to just print a second front end and bolt it on. This would allow you to tow in all the wheels and program something like a cyclone spin or something using a separate button on your controller. You could even have it be a separate rear end that you could just bolt on at a moment’s notice depending on what you’re using your car for at the moment.

What's your approach to motor control going to be for this project? STM32 setup is similar to a 1/10th tourer built by a guy called HammerFET on reddit. I believe that was put together in Simulink/matlab which is a pretty restrictive approach for anyone not working commercially. would be nice to see a more open foundation to software differentials and power distribution - Can imagine it would gain some traction and dev interest as an open source project.

Love the car, i am tho worried about the hub setup and how you have the bearing push in from the inside. when the car turns the only thing stopping the axel from pushing in is the pin and when it does push in it will hit the hub and ware it down. if you make a bearing that slides in from the outside of the hub also the pin will push onto the inside race of the bearing and stop it from pushing the axel into the plastic hub.

So is the basic idea of the programming going to be something like this oversimplification: To turn left X: Turn left wheel X Turn right wheel X * 115% Power left wheel Y Power right wheel Y * 125% So that your power per side obviously differs, but also the steering angle per side also differs?

I have a RC-car where I´m thinking about to make the rear axle steerable and thought about the same way of using one servo per wheel, since that way it becomes easy to change the toe-in dynamicly and thereby the driving-behaviour. But there is a drawback. With the conventional setup, the brace between the wheels equals out the momentum which get´s created at the turn-knuckles. Unfortunately I can´t attach a picture here to make it clearer. Imagine to look on the axle from above. When the wheels create acceleration this force is off-centered from the turn-knuckle´s axis, which means it creates a momentum. In forward dircetion this would result is both wheels would turn inside. In the linking brace between the wheels the momentums of the two wheels are eaqualing out. With a "one-servo-per-wheel" approach the servo has to work activly against this momentum all the time.

Great project, thanks for sharing. It inspired me to do a similar thing, hopefully able to show something soon. Out of interest, in stead of making your own hall-sensors to feed back speed, would there be a way to receive a comparable signal from the ESC? After all, the ESC switch phases based on the speed (also sensor-less motors).
