 | | Tempted in buying my first Mindstorms invention kit - 1.5 vs 2.0 ?
|
|
Currently debating in my head whether of these versions is the best to buy. I've checked the inventory with Peeron, all RIS kits appear more or less identical in their supply of parts. Does 1.5 come with ANYTHING that isn't included in 2.0 ? I would (...) (23 years ago, 16-Dec-02, to lugnet.robotics)

Hi Tobbe, My guess is that your friend actually got one 43362 and one 71427, the latter beeing enclosed in a 43362 case. If you look at 43362 enclosure photo ((URL) you see that there are 4 plastic pins in corners that are used to secure 71427 core (...) (23 years ago, 15-Dec-02, to lugnet.robotics, lugnet.technic)

The problem with that is you'd have to put the mechanisms together by putting axles over the first setup, which begins looking ugly. This is how I achieved the first walking part: 1.
