About the project:
Your requirements are precise, I have already worked with all the components you mentioned.
My son and I made a robot based on an Arduino Uno R3 and controlled it with an wireless joystick, maybe you want to add this functionality instead of the wired joystick
About me:
I am new on Freelancer.com but I have more than 16-years of experience on Electronics / PCB Design, 12 years on Embedded Systems, Embedded Linux, I have developed dozens of board with SoCs from several manufacturers (NXP, Broadcom, ST, Texas Instruments, Amlogic, etc).
I also have a lot of experience developing products for mass production, I can assist you in the manufacturing process too.

I have developed a carrierboard (motherboard) IEC 61000-compliant for a Medical Equipment. I did the components selection (together with my client), schematic, layout, GERBERS with DFM, assembled five prototypes and I have also made a Custom BSP (Bootloader + Linux Kernel + Root File System) and a small app (see last picture) to test the hardware and OS.
Best Regards.
