Have all the assembly complete for the car kit. the wheels do not fit! if i try to turn the motor over (with wires outward), the wheels fit but motor no longer fits the frame
Thank you all
Please provide us with the problem video so that we can help you analyze and solve the problem.
Please also check our assembly video for verification:
Hi there
Here is video link https://1drv.ms/v/c/cd3c1523c1a06759/EVWB8KxYeP1Lo8IZJWa1gdwBuQC4YV6ZD14h306d5b03sw
You are official sunfounder support?

Yes. From the video you provided, the motor assembly direction is correct, the Mecanum wheel slots are normal, and it should be able to connect to the motor. Please try to assemble and connect it again. Can other wheels be installed normally?
It is recommended that you remove the motor, assemble and connect it to the wheel, and provide us with the first-person video of the assembly.
Hi there

The correct installation method for the motor is with the wiring facing inward.
We recommend using a caliper to measure the dimensions of the motor’s inner and outer shafts to ensure they are consistent, as they should theoretically match.
Also, measure the dimensions of the wheel’s groove.
Have you tried assembling all four wheels? Are the results the same? Can the wires face outward but not inward?
Please ensure the grooves are properly aligned when inserting.
Hi there
So if I buy a caliper to measure and they dont mach ( i am sure they dont ) you pay my expense ?
What caliper is trustworthy for you? ( im in UK and want a nice long-standing tool)
Btw i don’t want go out to harm you or the company, i want to use this as a learning platform/ tool for myself and children.
Bruno Amorim
Under normal circumstances, the inner and outer shaft dimensions of the motor should be the same. However, since the motor you received allows for installation on the inner side but not on the outer side, we recommend that you provide us with pictures of both the inner and outer shafts, as well as images of the wheel’s groove.
We want to help you resolve this issue effectively and confirm whether a motor or wheel replacement is needed.
Thank you for your cooperation.
Have a new trouble now
So I finish the assembly and manage to charge it, got all lights on but the underside ones dont go blue and the car never moves with remote or app. On the wifi i dont have “zeus” name but hhave a “ESP …” network but is unable to connect .
Should i try tear this appart and rebuild ( at least the wiring?
The wheels are fine now
It is recommended to provide us with the operation problem and the problem video so that we can help you analyze and solve the problem.
After the Zeus Car starts successfully, you need to flip the smaller switch to the right to establish communication between the vehicle and the ESP32 CAM. After that, press the reset button to restart the code. At this time, you will see the chassis indicator light change from orange to light blue.
If the problem still cannot be solved, please re-upload the zeus-car.ino code:
Thank you so much for support, on Step 4 of firmware update, i complete all the steps (remove camera and USBs from desktop, the com is still not identified correctly), i select 1 and the command still seems to runs smoothly all the way . Still makes no difference in the car Control.
I still bet thats its my fault rather than having 4 motor broken in same kit.. How can we diagnose the motor? unplug from the board and "zapp " them?
If you want to control the car with the remote control, you need to upload the zeus-car.ino code to the Uno R3 development board.
Then follow the steps in this link:

If you want to confirm whether the motor can work properly, you can follow the tutorial link:
Or the simplest method is to use two Dupont wires to connect the motor to the 5V and GND pins of UNO R3 and power UNO R3. Under normal circumstances, the motor will work immediately.
Thank you once more. How i run the Firmware with linux ubuntu?
For uploading firmware, I recommend using a Windows PC instead of Linux Ubuntu. Please follow the steps outlined in our tutorial for the best results.
Thank you for your reply,
I think, one issue I didn’t consider before is “arduino com port not showing “ trend that is quite common as i looked. Already tested 2 windows computer.

Here are some steps to check for hardware connection issues:
- Check Hardware Connections:
- Try using a different USB cable or connect to another USB port (preferably the rear ports of the computer, avoiding hubs).
- Observe if the power LED on the Arduino board lights up to confirm it is receiving power.
- Device Manager Observations:
- Before connecting the Arduino, make a note of the existing COM port list.
- After connecting the Arduino:
- If a new device appears but shows as an unknown device or with a yellow exclamation mark, there may be a driver issue.
- If no new devices appear at all, this may indicate a hardware connection problem or a fault with the USB controller on the board.
I recommend updating or downloading the necessary drivers to see if this resolves the issue. You can search online for CH340 or CP210x driver downloads.
