A BIG quarter @TeamIndus

Rounding up a really BIG quarter with the GLXP team summit @Santiago, Chile – special thanks to our gracious host Team Angelicvm. Other than Astrobotic, most of the teams appear to be at a similar level of preparedness – happy to still have a shot at the big one :))

We managed to get the word out these past few months, and were written about a few times, some interesting reads for those you may have missed out earlier – Economic Times, First Post, Sunday Guardian, Silicon India.

Create, Synch, Visualize, Explore @SpaceApps

 

spaceapps-cover-e1364087307259The International Space Apps Challenge is an initiative by NASA and other partner space agencies, to throw open the opportunity of solving some of the most key issues in the realms of space exploration and social need, to citizens around the world who show the vision and power to bring a change. Crowdsourcing has never been so big, and never has had a better definition. We at Team Indus, share the same ideologies for incorporating innovation and believe that the International Space Apps Challenge will allow the bright and inquisitive citizens of India to participate in this global forum and make a difference.

Testing an OpNav Rig

Testing an OpNav RigAn appropriate function that inputs the base-line, focal length, resolution & depth will help define the “hardware rig”. You will still require test footage to be used for development of relevant control algorithms. Destructive testing of this rig is kind “easy” though prohibitively expensive.

However all we really need is video footage, at a reasonably high resolution, calibrated for accurate height from the “surface” – these when put together can simulate a free/controlled fall onto the lunar surface without actually destroying the test rig itself. So, the keywords are absolutely no damage to the test rig, Controlled fall/ Movement, Video footage, lunar surface simulations.

To make things easier, its easy to rotate the fall axis by 90 deg and make it horizontal, therefore instead of falling, the rig moves closer to the wall, which is pretending to be the floor ๐Ÿ™‚

Optical Navigation Rigs

Different baselines would pose different resolutions in visual odometry. Placing number of cameras might solve the problem but that is an overkill. Thanks to the variable focal length / Optical zoom feature of the conventional cameras a two camera stereo rig with a different baseline can be realized by having a longer baseline stereo rig with variable focal length.

Optical Navigation 101

Compact-er, lighter, great resolution on digital cameras today make them a great choice for fully & semi-autonomous navigation systems, especially in space. Starting with the basics...
