I am working on a similar app for the iPhone. Anyone interested in testing it before I release it to the App Store, contact me at:

Yup, you could do all those things. Simple averaging filters are easy (save the last N readings, add them all up, divide by N) Anomaly detectors are also pretty easy (large deviations from the average can be ignored).

The trade-off one has to make when inserting filtering between input devices and output is the lag inherent to such systems. A simple averaging system can be slow to act on a sudden true change in input (“turn left NOW!”) and anomaly detectors can filter out a sudden true change (“hit the brakes we’re gonna crash!”)

There’s a whole school of engineering called control theory that deals with these things.

But mostly you can just do a simple average and it works fine.

cant we eliminate the flipping of the numbers (hence the roomba) when we go beyond those limits in software? we could damp the too sudden accelerations, no?

Hi Pipo,
Unfortunately, all my Roomba stuff is in storage so I can’t try stuff out. Maybe the AMSTracker program has slightly different output now that the Perl script can’t parse?

Have you had any problems with the script lately? I’ve installed it, and it can read my macbook pro’s tilt data, but the roomba doesn’t do anything. Other programs to control roomba from mac work fine (like roombamidi2). I use the official irobot serial cable + keyspan adaptor.
Any help would be appreciated.

[...] Since Craig and I first created the PowerBook Puppet back at the end of 2005, there’s been quite a lot going on with the Sudden Motion Sensors (SMS) on the Apple laptops – for instance the the SmackBook and the Roomba Tilt Control. [...]
