stereoscopic vision ?

Fri, 05/17/2013 - 01:56
Does anyone in the club have a robot with two webcams used
for stereoscopic depth perception and obstacle avoidance?
If so, what software are you using?
Would it be easy to reproduce your setup?


Sourcing (China)

Wed, 05/15/2013 - 01:16
Anyone have advice on sourcing fabrics in bulk from China/Asia etc? Advice
on reliability and turn around?
I'm past the prototyping phase of this project I'm rambling through with my
brother, and I need fabrics for the exterior of this...thing.

Fw: Nice meeting you at the career fair!

Tue, 05/14/2013 - 02:48
Hey guys,
I met a nice young lady at the Devry Career Day (for high schoolers) last week and she wanted me to mention there are some LEGO Robotics instructor positions available through Galileo Learning this summer. The information is below if you are qualified, interested and would like to contact Aubrea.

How to value a robot company

See robot Baxter on youtube-you teach by showing, no programming conference in Santa Clara,CA 5/23/2013

Tue, 05/14/2013 - 02:48
Folks, had you seen this manufacturing robot? As well as the link to the Society of Mfg. Engineers conference coming up? For those job hunters out there in robotics….

Neato_node on Raspberry Pi, no joy so far.

Tue, 05/14/2013 - 02:48
This is pretty technical, so unless you use ROS, spare yourself the headache and skip the rest of this message. Sometimes I find writing down my steps helps me debug.

1. I have the neato_node running on Unbuntu 11.10 and Groovy using [link] instructions, with the added modification of changing USB0 to ACM0 (in the file) on my laptop. (I then can use RVIZ to detect object about 15ft away.)

What's the best way to replace a small motor gearbox with pulleys?

Tue, 05/14/2013 - 02:48
I've been experimenting with using pulleys and belts for a robot drive
train. My experiences so far are very positive: belts are quiet and seem to
have less backlash than gears I'd like to design an all belt and pulley
drive train. My only problem is finding a pinion pulley that fits that
shaft of small motors. The smallest pulley that I found has a bore of 3.2

Attention: HBRC @ Maker Faire!

Mon, 05/13/2013 - 23:28
Hello folks,
We finally got accepted into Maker Faire [link] but they didn't give us the number of passes requested so here’s what we’re going to do… reply to this email IF you will be available both days of Maker Faire (May 18 & 19) AND have at least one HomeBrewed Robot AND will make yourself available for booth duty for at least 3 hours per day. If you are not interested in Maker Faire chatter please avoid the “Maker Faire” subject header. After gauging interest I will inquire about more passes (if necessary). I realize there are some family teams in which case the best thing to do is have more than one homebrewed robot but if that’s not an option perhaps we can get additional passes; again, I need to gauge interest before requesting more passes. Please reply quickly as this event is only a few short weeks away.

Thanks again for the opportunity to speak last night. I had one quick request: I noticed that some of the members were video taping the presentation. I don’t have a problem with the video taping but for those that did, can you ask that they refrain from posting it publically on the internet? I don’t mind if they share it among the club members….I just want to avoid it being totally accessible to the public. Even though the information I shared was public knowledge available on the robot maker’s web site, I’d like to avoid any potential bad guy from learning more about the robot or SWAT tactics. Thanks!

Question about casting

Thu, 05/09/2013 - 20:48
I wanted to make more Nanosumo robots but I need wheels. The 3D printer at
Techshop can't make the 0.5mm features. I thought I would try casting.
Before I do, does anyone know if it works for features that small, and is
it cost effective? The wheel is 11mm in diameter and 4.1mm deep.

Bring your RoboGames robots to show and tell tonight!

Wed, 05/08/2013 - 04:11
At RoboGames this past weekend, HBRC robots were everywhere! We had
numerous robots in Table Top Nav (of course), and I also saw HBRC bots in
Ribbon Climber, Mech Warfare, Soccer, Fire Fighting, MicroMouse, Sumo,
RoboMegellan, Best of Show, and Balancer Race. It's inspiring to see such
a wide variety of robots from members of our club. If you entered a robot

Wednesday Meeting

Sun, 05/05/2013 - 23:07
I thought I would bring my Nanosumo for show and tell but it's so tiny no
one will be able to see it. Is there a way to project onto a screen from my
video camera?

Forgot netbook charger at Hacker Dojo

Sun, 05/05/2013 - 01:56

I do not know what it is with me and forgetting things at the Hacker Dojo.
This time I left my netbook charger plugged in into the outlet extention on the table in
the room that the SIG was in.

If anyone took it, may you please somehow transfer it to me?

I'll be at the Robogames tomorrow, as well as on the meeting on wednesday.
