Good evening! In WeDo 2.0 set there is only 1 motor, which can be remotely switched on and off by using the iPad app (by writing a Scratch program). Also motor rotating direction can be toggled remotely. As an inexperienced LEGO builder I wonder if it is possible to build a remote-controlled vehicle out of 280 WeDo 2.0 pieces, which would be steered by changing the motor rotation direction. http://i.stack.imgur.com/jrF3t.jpg Initially I was thinking of using a caster wheel, which would roll straight when vehicle drives forwards. And it would snap to a certain angle, when motor rotates in the other direction. But then I have got a nice advice to use a ratchet instead. Unfortunately, it doesn't work well. There is too much friction - on the axles of all 3 wheels and on the rubber band: I wonder if experienced LEGO builders can propose a better vehicle out of WeDo 2.0 parts than mine: http://i.stack.imgur.com/h7KYk.jpg http://i.stack.imgur.com/ePo6o.jpg http://i.stack.imgur.com/kRJKS.jpg And I feel that my Scratch program for iPad can be improved too, since it is not very responsive to user input (when touching the 4 green arrows): http://i.stack.imgur.com/ecz1W.jpg Thank you for any suggestions Alex -
Summarizing: - WeDo 2.0 - Spike Prime - Mindstorms Ev3 I believe that, since their introduction, automation and then coding were supposed to represent the natural evolution of Technic,however they ended to be confined in the educational niche. Moreover, wouldn't have been better, on a marketing level, to avoid the fragmentation in three themes? I understand that there are different ages and costs but I think that Lego could have stuck with only one sub-brand, whatever it was, then proceeding to diversify. A single sub-brand would have increased the exposure, hence the sales. Confusing marketing, wasted opportunities. -
I working on custom instructions for a WeDo 1.0 and trying to add a rubber belt connection between parts 4185 (Wedge belt wheel) and 6590 (Bush for cross axle). But it seems that V-belt part in LDD is not flexible. And I wonder is any models for LDD from WeDo 1.0 like sensors and USB hub?
