Components needed for sumo robot?

I just wnna to ask about which components needed or the necessary components that should be there when I wanna to start building my own sumo robot
Here it is some components that I think will be needed is there any thing else i missed

  • line follower sensor
  • Ultrasound sensor
  • Wheels
  • Dc motors
  • Base
  • Breadboard
  • Jumper Wires
  • Battery
  • Servo motors

Wifi transceiver chips plus funduino joystick.
Screws, nuts, bolts, washers.

Arduino or other computer, battery box.

is there any thing else i missed

A plan.

If you have an extra arduino board, such as a spare UNO board, then it's possible to use wireless communications chips (which have onboard antennas) for remote control of your bot.

Eg.... nrf24L01 chips. Just google things like "remote control zumobot"

In a Sumo competition you can't or should not have radios. A bluetooth device like and HC05 or 06 is a good remote debugging whilst build the bot and coding.

Yes it should be autonomous?

For all mini sumo comps it should be. There are RC class sumos but are larger bots. I assume you are wanting a mini since you are listing servos.
