Today is the day I start to assemble Orngy, the backyard rover. Orngy is a 4-wheeled smaller version of the 6-wheeled Mojave Rover. I am using the same drivetrain and differential setup as the large rover. Based on the last two weeks’ solar testing, I will use two 10K mHa batteries and four solar panels. Splitting the batteries between compute and motors.
I have a video showing the working drive on a test platform
I don’t have the code or a wiring diagram from the test in the video. I know, shame on me. This time I will get it added to the Knowledge Base and hopefully not lose it.
As I remember right, the code was split between mission control. Mission control was PHP and MySQL based and stored the command to run. The command would be which servo do to what and for how long. The rover would then query the server now and then, get its commands and execute them, then send back the results and readings. The rover was programmed in Python 3.
Anyway, that is the plan now. Get the thing moving and solar charging out in the backyard. I will then program more as I go and add more sensors as I get time.
What I hope to learn.
- How to get this thing moving?
- Can I get enough solar power to charge both batteries?
- Will there be enough power for all the sensors?
- How should the camera arm, elevator, or lift work?
Lots more coming up, as I get time to build and post.
