Adventures in STEM- making robotic progress with Ardunio

Arduino is not only a fabulous circuit board, but it is also it’s own language with its own grammar and syntax rules. Using the Arduino basics course from Stan Winston School of Character Arts, I was able to program my Arduino Uno board to do some very simple functions.

Such as:

Programming a buzzer to make sound,

Programming a servo to move,

Making my first code!

Which has all lead towards me assembling my first actual robot!

First test of my Arduino robot Rosie!

Posted by Katherine Hannaford on Thursday, December 21, 2017

I am calling my robot Rosie after the robot in the Jetsons. There are not enough female robots in popular culture and my long term goal is to eventually have Rosie talking like Rosie from the Jetsons! My Rosie is a 2 wheel drive platform from Jaycar, with an ultra-sonic sensor on the front so that she avoids obstacles. Assembling just the platform was tricky as the instructions were hard to find and not linked in the assembly instructions for the whole robot!

The first modification I want to make to the robot is to add a switch so I can turn her on or off. At the moment, I can only turn her off my removing a battery from the battery holder. I also want to experiment with the robot on different surfaces. I was noticing during the first drive that, the wheels got stuck on the thick nylon carpet in my house. I want to compare how Rosie runs on low pile carpet, tiles, and concrete.

What I haven’t been able to achieve yet is to take the Uno board and several other components and write custom code for it yet. So far, I am relying on code that is available in the Arduino Library or on project sheets. My next experiment for Rosie is to add a line trace module to Rosie’s base chassis and see if she can follow a line. My next experiment in coding is to see if I can combine a button press input to a potentiometer and make a joystick work.
