Unlimited CNC Robot Blog #6
I wanted to post this blog before I post my final blog tonight. I found a big error in my code and wanted to update it now.
The error I made was I had my line sensors reversed to what they needed to be for the right readi...
Connectors
Going back to the block diagram, I will add a few comments here.
As a general principle, I would like to be able to disconnect the two engines, two sensors and two power supplies (not pictured in the diagram: 5V power bank and 6V engine p...
It has been a long journey, filled with knowledge. At this point, my RARM is almost done.
I would like to tell you a little bit of what was my path to building the robot.
Let's get started
In the beginning, when I started blogging I used ...
The most important (and fun) part of The Robocat is the cat. We chose paper mache to make the body. This blog post is just about how we made the paper mache cat and attached it to the robot chassis.
We used a paper mache process that is ...
This blog post is all about putting the functional components of The Robocat together. I made use of TE Connectivity connector products to make The Robocat a reality.
I used the M3373 SL005 multipair cable for all board to board con...
Autonomous navigation
The navigation software is implemented as a Finite State Machine (please refer to the next figure).
The FSM has four states:
START - initial state
FREE_NAVIGATION - no obstacle or obstacle is far away
AVOID_O...
In this post, I will write about the user interface and remote control application developed as part of this challenge
Local display
Rullit has a local OLED display with a resolution of 128x32 pixels. The display shows the information shown in...
The Robotcat has a machine vision component, which hopefully allows it to “chase” a laser pointer. Machine vision requires considerably more compute power than the Arduino Uno can deliver. To supplement the Arduino Uno, I dec...
