Let's Make Robots!

BoB the Biped and me: We love quiet sunset walks on the beach.

This is just a happy blog about how my BoB is fully mobile and can navigate obstacles. The sensor is just hanging loose but if angled the right way it works fine :) I'm using an HC-SR04 sensor with the newping library for fast distance readings that don't put a big hitch in the smooth walking. I have the library set to timeout the sensor if there is no signal after about a foot or so. Distance readings are only taken while BoB is facing forwards, be it on one or both legs.

BoB the Biped with his Arduino motor cortex

After a lot of reading and some minor language barriers I've finally gotten over my fear of Arduinos. Thank you, BoB. He was in need of some floating point math so it seemed like a good time to make the transition. I find what I write looks a lot like BASIC but I'm just glad it works.

BoB the Biped and me with v0.91 board design

I got my pile of BoB parts from isotope yesterday and I was stoked to say the least. He even printed out a JAX name badge for me \o/ Thanks man! My BoB is glow-in-the-dark blue ABS and it luminesces as advertised. Blue Glowy BoB... mmm.

Initial test fits showed that there was going to be some grinding work in my future to make things work. One change I made to the original build list was using an HC-SR04 for the sensor. The sensor holes in the head were too close together so I removed some material on the outer edges to make it fit. It's real nice now.

LU2MI2 build log: July 11th, 2013

As noted elsewhere I had to start something new to add updates to this project and from now on it will be in the form of blogs (it's about time, huh!). To summarize the project's status, things were going well until I went to test all the subsystems together on the actual chassis. I had forgotten to breadboard test the 3.7g servo at the 3.3V I was going to supply it with and it turns out it hated it.

What to do when you have a project idea but don't know where to start

Everyone starts at the same place in the very beginning: You have a great idea but don't know how to do it. What to do?

The first thing you do is probably (should be!) a seach with Google/Bing/whatever. Chances are you will get a bunch of links that have a lot of info that isn't much good to you in the beginning (but later on you might find they were full of gold). This means you need to break down your project into smaller bits.

BoB's and filament

I love the invasion of the BoBs! Like a herd of little boxy Android droids. Although I don't have a 3D printer I was wondering how much filament was used to make one of those guys. More that I was interested in the cost involved as to have a better idea on how much to offer someone to make a BoB for me.

Sorry if it's mentioned in a post somewhere, I didn't see it.

Experience with DFRobot's PCB service?

I've had boards made at seeedstudio and OSHpark and both have pros and cons. I was thinking about dropping my next gerber file load on DFRobot but wanted to see if anyone has used them before.
