I have been working on this project as a way to get my kids thinking about robotics/ programming and 3D printing. plus who doesn’t want a little rover to drive around and pick stuff up from the couch!
Goals of the project:
Wireless rover that can be controlled remotely and eventually off site via web camera.
The rover is a print of donboy’s Autonomous-Webserved-Tanktrack-Robot on thingiverse.com
Coding and set up found in these tutorials on instructables.com
WiiMote Controlled Servos with RaspberryPi by CyprienA
Raspberry Pi and Wiimote controlled Robot Arm by Boardmaster
and Make OWI Robotic Arm self propelled on tracks controlled wirelessly by the Wii controller and Raspberry Pi by Gerald Strope
Step 1 – Printing
the parts were printed in orange and light blue PLA.
Step 2 – Hardware
the servos were old servos that were gathering dust in my fathers basement.
Step 3 – Mounting/Assembly
i did everything i could to avoid screws, most everything was put together using filament rivets
the brain – deciding how to run and control this rover has taken a decent amount of planning. i started with an arduino nano, but when it came time to control it i struggled to find a ideal/cheap configuration. i came to the realization that a raspberry pi would be a better approach.
Programming – as i am not really a programmer it has been difficult to get things working. i had a basic loop running on the arduino originally but for now once i switched to the pi he has been dead.
I have been working on getting pwm working with the raspberry pi here is my progress as of Febuary 4th 2016
I will continue to update on my progress as things progress.
