I'm brand new to robotics, never touched it before but my son is doing it at school and I'd like to build one with him.
I actually make a small income from 3D printing and am an instrument tech by trade, so I can fabricate and solder very neatly.
We have made a start on this project:
Straight away I didn't like the 3 piece chassis and there was no proper mounting points for the Arduino, so I designed and printed a new chassis (in orange).
All the help I'm after at this stage is how to wire it and some advice on which components to buy.
An Arduino UNO
2x continuous rotation servo. Springrc Sms Australia | Little Bird Australia
A bunch of 2S lipos I already use on quads, and a balance charger to suit.
Some questions are:
Can I run these 2 servos straight of the UNO? It would be good for my first project, I won't want to add any other servos to this one.
If I need to use a shield, is this one too advanced for this project? I'm happy to buy a simpler one.
Is there a cheaper option for sensors than 2 of these? Parallax Pings Australia | Little Bird Australia
If it has to be these, so be it.
On the front bumper are apparently 3 IR proximity sensors, and he says this:
"The sensors on the bottom are the Adafruit VCNL4000 Proximity IR sensors. Unfortunately, I would avoid using these at all cost. What they didn't make clear is that you can't change the I2C address of these, which means you can only normally run one sensor. Since I have more than one sensor, I had to try and hack it together using an I2C bus switch which lets you run multiple I2C buses. I then got busy, and haven't had a chance to write the code for them, so at the moment my rover is just using the PING ultrasonic sensors."
What would be good IR sensors to get?
Once I've got everything I need ordered, I'm hoping some of you may be able to show me what to connect to where.
I won't even start to get into programming it yet.
Thank you very much in advance to those kind enough to help me out.
This is one of those father/son things, and I'd like to see it finished successfully.
