I've been developing a CNC controller for DAGU. The project originally started late 2012 but got shelved because of other projects. Now we've dusted it off and plan to finish it in the next 6 months. Unfortunately blog post don't support video so watch the video that explains the basics by clicking on the link.
So much is happening so fast, I'm starting this blog to document what is going on with the bot, so I can look back on my thoughts from time to time and see how they developed. Others are more than welcome to participate! I'll start by throwing in a diagram and some fun video!
This is a simple autonomous robot based around the Basic Stamp2, it has obstacle avoidance using a home made IR Transmitter and Receiver as well as obstacle detection using bump switches and copper whiskers.
I recently came across this web site talking about how to make track systems (as in RC tanks). It has some really interesting options. If you are thinking about making something large and tracked this might be worth a look.
I haven't been able to substantiate or dispel the note about our friend and my likely relative hoff70. What I can say is that repraff.com lost its place on the web two days ago. It's safe to say that if hoff isn't dead, in some sense he's killing his online identity.
For a speedometer project with arduino, I need to have two main functions. One which detects if you input the distance you would like to travel and gives you warnings that the speedometer will run without telling you distance left if you don't put an input in 10 seconds from that point (40 seconds into the program). either if you do input that information or if you don't you will be brought into the 2nd main function which actually begins the computation for the speedometer.
Been trying to understand inverse kinematics for programming my quadruped Crap-Crab. I started out by reading Wikipedia's version, which lost me completely (WTF?). But then I found the explanation by this guy and it turns out, as I thought to begin with, that it's simply a matter of applied trigonometry.
