VADER Spider Controller Arduino Upload Issues

So it's been a while since I last got a chance to work on VADER (see http://letsmakerobots.com/node/39884) , but I recently was able to dust him off and finish up the wiring. VADER is a Service Droid mounted on a Rover 5 Base with a 4 channel motor controller and a Spider Controller.

LIDAR Lite Development

Sparkfun had a link to an interesting article about supporting the development of LIDAR-Lite:  http://www.dragoninnovation.com/projects/32-lidar-lite-by-pulsedlight

Rather pricey but if it can provide better scanning capability over the ultrasonic sensors it might be fun to use. Any one heard about this?

Making Your Own Jumpers

I recently wired up my Vader Service Droid, but I'm not happy with the resulting rats nest of jumper wires. The mess is partially due to the pre-fabed jumper wires. I'm stuck with jumpers that are tool long in a lot of cases and too short in others.  I managed to cluge it all together using some header pins and with solid wire, but the result feels...less than optimum.

Has anyone had success in building their own F-F and M-F jumpers to custom lengths? 

LMR Wiki Content

Hello LMRians,

Had an email conversation with Frits, THE LMR Webmaster, and he gave me the scoop on a soon (days not weeks) to be added Wiki to the LMR site. If you aren't familiar with a Wiki, look it up on the mother of all wikis, Wikipedia.org.

The LMR wiki will be the Go-To place for articles on all the various aspects of making robots and possibly articles (not reviews) about the various robot kits on the market.

In anticipation of the new wiki I thought it would be a great idea to:

Vader Vibes

Starting this blog as a place for me to throw down my thoughts about options for my Service Droid, VADER:

At times where I'm anxious to work on Vader but can't, atleast I can blog about it!  Right now is a good example: my 2 month old daughter is asleep in my arms. I may be having to type with one hand but the progress feels good!

First off, I'm considering a tweak to the acronym."Very Advanced" is a little over the top. Maybe "Virtually Advanced" or "Very Amateur".

A couple functions:1) Remote Control 2) Autonomous avoidance 3) Autonomous object retrieval (hopefully)

This is my Service Droid. Meet VADER,  the Very Advanced Droid Exploration Robot. Ok, I admit it, the name is a stretch but it was fun to come up with.  Everyone … Read more

Service Droid Wiring w/ 4 Channel Controller and Spider Controller

Been working on wiring up Vader (my Service Droid) using a Rover 5, Dagu 4 Channel Controller and Dagu Spider Controller.  Since I've never used this channel or these boards before I drafted a poor man's schematic in Powerpoint of what I think the wiring should be.  Would appreciate a peer review before implementing it. It's a little rough, but when cleaned up it could be useful to anybody else building a Service Droid kit as well.

Some time ago my two boy (ages 10 and 9) really wanted to build a robot. I obliged but I wanted them to learn a lot of basics along the way. I also didn't want to … Read more

Affordable Scanning LIDAR?

I read an article in ROBOT magazine about the NEATO XV-21 robot vacuum cleaner than apparently use a scanning LIDAR to map a room before vacuuming. It sells for $400 USD on RobotShop: http://www.robotshop.com/productinfo.aspx?pc=RB-Nto-10&lang=en-US  It made me wonder - if the entire robot can sell for that much - how much would the scanning laser rangefinder be and where can I find one?
