popular ! Final sale Thames & Kosmos smart car robotics set & extra sensor motors stem toy

Final price Thames & Kosmos Smart Car Robotics experiment kit for 10+ kids. It is in outstanding used condition, all 211 pieces counted and double checked, so shop with confidence. It comes with its original box as shown. The kids can construct eight different futuristic models as shown on the photo as they do with Legos.
One thing to mention is that the original app can’t be downloaded from the App Store, only recent app, the manufacturer retired the old, check the App Store. We got 2 new motors & the sensor from the manufacturer (which was not in the original set) working with the new app. Note: only 2 motors are working with this new app so you need to modify the designs to make it working with the new app (originally there are 4 motors). Please take a look at the photos how we modified the 3 wheel car. You can program it, the sensor is working! I can send the video of the car to show how it works!
We paid newly-released $120 & new kit $75! Bundle & save! A gratis gift comes with this set!
