Overview - Black Bug
This robot is a small 2 wheeled / caster platform that I built from scratch. I figure if my students have to build one, I should too... Plus this project page can serve as an example of what I'm looking for when they update and edit their projects and blogs.Current Project Status:
2/28/2018 - worked on line follow... but can't figure out the Pololu QTR-8RC line following sensor. I think they are good product, but the docs are terrible...2/14/2018 - added a rose for Valentines
2/12/2018 - Updated Project Blog page, added current state photos
2/11/2018 - Updated the power harness to use an EC3 battery connector. See the Mechanical section for an image of the power harness.
2/2/2018 - Kicked off this project. Initial platform was based on a Karlsson Robotics Magician Chassis but then I cut out a new frame from 3/8 plexi. The Black Bug will be initially controlled by an Arduino
Next Steps:
List all the current steps in order of priority. Mark "Pending", "In Progress", "Road Block", "Done"- In Progress Add a Castor to the back
- In Progress Work on the code to slow down the speed of the motors. They are currently running too fast with a 7.6v Battery
- In Progress Strip off the paper on the plastic
- In Progress Add the line following sensor - I'm considering using the Analog version of the Polulu reflective sensor
- In Progress Add 4 limit switches to determine the edge of the table. I need to figure out the way to connect these to the 4 corners of the robot
Mechanical Configuration:
This section describes the Physical / Mechanical configuration of the platform... How does it work from a hardware point of view.2/12/2018 - this is an image of the power harness that gets power from a battery to the robot. I'm planning to use a 7.6 Volt battery and EC3 battery connectors. This let you use the motor drive card to provide 5 volts for the Arduino, and have an ON/OFF switch for the battery..

Sensor Package:
This section describes the Sensor configuration of the platform...- Pololu QRT-8RC - this sensor is really hard to figure out. I think it's probably really good, but the docs are terrible. I do have one student who seems to have it working... so I'll go talk to him. Here are the docs I have found:
Data Sheets and Resource Links:
Here you will find links to any data sheets for components used on this robot platform. Also links to any Instructables or YouTube sites- Arduino-based Line Follower Robot Using Pololu QTR-8RC Line Sensor - Instructables - (2/28/2018) I have not tried this code yet.
- PID Based Line Following Robot With POLOLU QTR 8RC-sensor Array - Instructables - But I could not get this code to work yet... I modified it to have only 6 sensors, but it runs the motors forward, but does not react to the sensors or the line. (2/28/2018) I'll let you know if this changes :(

Please describe any source code and link to it. Best to have a GitHub account and host your code there.<description and link>
