I'd be curious to know how this will stack up against the EV3 system. It's also interesting that they include 4 motors, ultrasonic and color sensors, but no touch sensor. EDIT: other interesting notes: the motors have absolute positioning, and the stuff uses new connectors.

I've heard that this is because the color sensor can be used in place of a touch sensor in most cases, though I haven't tried that myself. Also nice that the hub has a 6 axis gyro/accelerometer.

> No force sensor? > Dan: Yep that's correct. We had it early on in our product exploration, we found we used it very little in the play. It was something we were weighing up; should we have an extra motor or should we have a fourth sensor? And very very quickly we said we'd much rather have four motors in the set, than a fourth sensor, because we could use the tap of the hub or the buttons on the hub. We often use the color sensor as a button as well, because it's very good at detecting a finger and a touch. There's an interesting interview with the product designers over at New Elementary: http://www.newelementary.com/2020/06/lego-mindstorms-51515-robot-inventor.html http://www.newelementary.com/2020/06/lego-mindstorms-51515-r...
