the motor is 300rpm
no idea about its MBTF
and no idea about the sleep ring

anybody here has tested/tried this kit and can provide a reasonable feedback ?

thanks  :-+

Looks cool.

I would have use a prism mounted on a gyroscope and leave the laser and detector fixed and add also tilt control to get more than just a 2d section.

I hope the laser is safe or it will blind your pets :)

this quote is the summary, what is/who did it/etc

Neato Robotics Hacking, 2014

This site is devoted mainly to iRobot hacking. Just for reference extensive Neato hacking has been developed you can find in Google search. The interest has been in using the lidar out of the Neato, and interfacing Neato's system to other robotics control systems (not so much interest to vacuum users). Complete software packages have been developed, e.g.

https://www.labviewhacker.com/doku.php?id=projects:lv_neatolds_interface:lv_neatolds_interface

http://www.ros.org/news/2011/02/neato-xv-11-laser-driver.html

Interesting the technical details of Neato's lidar invention was described in an engineering journal article posted at RobotShop http://www.robotshop.com/media/files/PDF/revolds-whitepaper.pdf

As initial sales promotion when Neato was introduced several years ago, Neato encouraged hacking the lidar and held a contest for it, to stimulate exposure. Now the results have been polished into full software packages. The company still does not sell the lidar unit separately for robotics -- to help sell vacuums...

[edit] another Neato post this section on adding bluetooth (possible only on older system boards including a serial interface header besides the USB) http://www.robotreviews.com/chat/viewtopic.php?f=4&t=15349
Neato labels board several ways including a display on the LCD, with older boards showing up to 113, and hand marked Rev.7 on the board, and Rev.1 on silkscreen. Old and new photos:
old with serial http://xv11hacking.wikispaces.com/XV-11+PCB+Information
New without: http://xv11hacking.wikispaces.com/PCB+rev.+64
(Besides the port change the major incompatibilities are a new charger system incompatible with old chargers, backwards compatible new, and a pin connector for the LCD cable instead of the bare ribbon cable clamp.)

As a result of the initial XV-11 hacking frenzy, you can obtain a complete Lidar unit for your Neato for under $100 with free shipping from ebay and can sometimes find Lidar sellers w/shipping for around the same price on Amazon.

anybody has the following paper ?

Code: [Select]
Cover story in the September, 1993 Sensors magazine.
Frequency-Modulated Laser Ranging by Neal Woodbury & Michael Brubacher

in case, could you contact me by private message ?

laser rangefinder, OSLRF-01 model

have you seen this ?

Quote
The OSLRF-01 is an open source laser range sensor that works on the time-of-flight principle. It includes a laser, detector, optics and sequential-equivalent-time-sampling (SETS) circuits. Designed as a bare-metal front end for a laser rangefinder system, the OSLRF-01 is a high quality sensor that can interface directly to the ADC channels of a micro controller. The OSLRF-01 is ideal for obstacle detection, distance measurement and laser rangefinder research.

Nice.

Too bad the OSLRF-01 is not available
http://www.lightware.co.za/shop/en/4-lrf-modules

but.... The kit is for just $32 (No laser, nor components, I'm afraid)
http://www.lightware.co.za/shop/en/lrf-components/26-oslrf-01-kit.html

But the downloads has a manual with the BOM
also some laser diodes listed on their site:

yeah, we could still assembly the circuit by ourself  ;D

just wandering WHY not to use the phase drift method instead of time of flight one :-//

Line Scan Image Sensor Demonstration Kit
LIS-1024, LIS-500, RPLIS-2048, ELIS-1024, DLIS-2K/4K and SLIS-2048

also, have you seen the Line Scan Image Sensor Demonstration Kit ?
This kind of technology is a sort of super reflective angle LIDAR,
an idea that makes things simpler and cheaper, Neato has used this idea for their $50 USD LIDAR.

the lr4 is a 150USD LASER RANGEFINDER which could be used in robotic things, and it could be used as lidar if used with a rotating base, in case just to make you known about its existence  :D
