Black Bug - Tell Me About Your DD Bot - Pinned Post

Differential Drive Robot's Resource Page

This is Mr. Burnham Project: This is where you will post your Robot progress. Post Engineering Plans, Sketches, Links and Photos.  See Robot Club Rubric for the quality and expectation of the posts contents.
Overview: This robot is a small 2 wheeled / caster platform that I (Mr. Burnham) built from scratch.  I figure if my students have to build a robot, I should too... Plus this project page can serve as an example of what I'm looking for when you (my Students) update and edit your projects and blogs.

2018-2019 - AM/PM Jim Burnham

Jim.The.STEAM.Clown - AM/PM - 30 - Power Harness

Next Steps:

1. Mount the on/off switch.  right now it's just dangling
2. Mount a battery holder on the bottom part of the Bot.  Right now the battery is just loose and I have taped it down.
3. I need to look at changing the motors for a higher gear ratio, so they will run slower
4. I need to pick a method to sense the edge of the table
5. Right now it runs with an Arduino Controller, but I was thinking of adding a Raspberry Pi too

What jim.The.STEAM.Clown Did Today:

• This is the way I connected the EC3 battery connector.  
• These are better connectors than the default molex ones that come default on the batteries. 
• I had to be careful not to short the battery when I cunt the wires.  If you do this, make sure you only cut one battery wire at a time... otherwise you could short the battery as you cut through both wires.
•   Having a Switch to turn on/of power really helps

Jim.The.STEAM.Clown - AM/PM - 30 - WoHooooo got the motors running

Next Steps:

1. I need to look at changing the motors for a higher gear ratio, so they will run slower
2. I need to pick a method to sense the edge of the table
3. Right now it runs with an Arduino Controller, but I was thinking of adding a Raspberry Pi too

What jim.The.STEAM.Clown Did Today:

• Mounted the original motors.  These may be too low of a gear ratio for a table top bot.  They seem to work fine for on the ground.  
• I soldered on wires to the motors and then tested that they worked with a 5 V DC power supply.  They worked.
• I then connected the motor controller, and tested the Arduino code.  I’ll add links later to the Resource page.  

Jim.The.STEAM.Clown - AM/PM - 30 - Cut out the Frame for the Back Bug

Next Steps:

• I need to look at changing the motors for a higher gear ratio, so they will run slower
• I need to pick a method to sense the edge of the table
• Right now it runs with an Arduino Controller, but I was thinking of adding a Raspberry Pi too

What jim.The.STEAM.Clown Did Today:

• Created  a frame.  I looked at lots of 2 wheeled robots, and then sketched a design on plastic.  I then cut this frame out.  I have not pulled the paper off the plastic yet, as I may want to draw on the spots where I drill more holes... but eventually I'll pull off the paper.  But it’s my first car robot… WoHooooooooooo
