A video tour of my autonomous #rover  project, Laika. It's based on #Arduino Mega 2560 boards, plus a ton of add ons.

My picture of the #Moon shot on Dec. 19th at a public #astronomy outreach I led for the #DAS (Delaware Astronomical Society - http://delastro.org/) at #Bellevue State Park in #Delaware. #Nikon D3300 DSLR camera on a #Celestron #NexStar 6SE #telescope, f/10 (fixed), ISO 6400, 1/3200 second exposure. Post-processing for sharpness, contrast, and levels in #Gimp.

I think Laika (my autonomous rover project) is getting complicated enough to require me to get some standoffs and acrylic plates and start mounting components....

From left to right we have: 5v 10A power supply for servos, science platform with {10DOF, TSL2561, SI1145, HTU21D-F, RTC, 16-channel servo controller}, then top to bottom are {two pan/tilt systems with two servos each, Pixy CMUcam5 AI vision card, dual Arduino Mega 2560 computers, and the navigation platform with GPS and micro-SD data logger}, LIDAR, WiFi card with separate 9v power supply, 6v solar panel, 6600 mAh LiPo battery pack, DC/solar charger controller, and finally the Powerboost 1000C step-up transformer. And the software to control everything is well over 1,500 lines now, including the C code with C++ libraries I wrote.

Today I'll be working on some reliability issues (like, why the radio data connection to the Mission Operations server only works some of the time). I'll also fire up Eagle CAD and continue working on the design for the power bus controller; I'll eventually have five of the solar panel/charger/Powerboost/LiPo combinations to power various components, and I need some way of powering up the components in the right order. Custom PCB with voltage regulators, battery level monitors, and TO-220-package transistors to the rescue. I also want to have a smart power supply to the power controller board, so it'll use 5v from the strongest-charged LiPo OR DC power at the barrel jack if it's connected. Fortunately, the barrel jack has a "sleeve connect switch" in it, so I just need to determine how to build a circuit to use it.

Yeah, this started out as a "basic" robotics project....

I just submitted my proposal for an IoT roadtest of this new kit from Element14.

I'm working on an autonomous rover project I call Laika  (since my daughter recommended I name my rovers after famous explorer dogs). This is basically an advertisement for +Adafruit Industries  :-) because most of the parts come from there. You can also check out my blog at scattershot.complexsys.info and look for posts with "Laika" in the title. Those will have even more information!

Story
Tagline
Dad, sailor, shooter, photographer, and complexity geek.
Introduction
I specialize in advanced information security research and implementation, so I study quite a bit and have eclectic interests, many of which are associated with the science of complexity - physics, economics, mathematics, and statistics.  I am also interested in photography, sailing, kayaking, hiking, and geocaching.
