Hardware for simple Robot

    Hello,

    I'm new to robotics and I can code in C++.

    I want to make a simple Robot for my Cat.

    It should do some tasks I code on my Raspberry Pi.

    First of all it should activate on a defined time of the day.

    And it should be powered by batteries.

    Second: It should navigate based on 2 axes.

    I want it to swing a stick horizontal at a maybe 30° angle. And it should vibrate.


    Now the question: What Hardware do I need? I already have a Raspberry Pi and I will build a Case at my own for this.


    Thanks for your help!


    PS: English is not my main language. So sorry for faults.

    At least two small motors, for the two axes (one that rotates and the other that advances). I imagine it as a ball, so I recommend you see the design of BB-8, a company sells one like that. You need the battery: https://www.amazon.com/Pisugar…Accessories/dp/B07RC649ZC


    I would put a gyroscope and accelerometer, a little horn, a vibrator. You can add a thousand things to it. I guess what I say is basic, I think you should ask a more precise question, what is the design you have?
