You're right... But there are quite a few practical issues to address, specially the exact position of bricks on the "Turing strip" to be able to pick them... That strip should also be much longer for any "practical" use (and I'm running short of (...) (25 years ago, 30-Jan-01, to lugnet.robotics)

What is the status of version 2.0? It has gotten impossible to find older sets. Fry's has a couple that have been opened and are missing software (and possibly parts), but they will only drop the price to $179. What a rip-off! (25 years ago, 30-Jan-01, to lugnet.market.shopping, lugnet.robotics)

(...) Yes - but if you've been following the discussions about dropped counts, you'll know that the standard rotation sensor is pretty inaccurate when you set it up like that. It likes nice *fast* rotation rates. (25 years ago, 28-Jan-01, to lugnet.robotics)

Matthias, this is easy to do without a new part. You use a normal differential, put one shaft in one side, the other shaft (but reversed) in the other and connect the rotation sensor to the output. You get a positive count if the right wheel is (...) (25 years ago, 28-Jan-01, to lugnet.robotics)
