I wrote a first cut at it and it didn't work, just like the support question suggested: import (...) (25 years ago, 20-Jul-01, to lugnet.robotics.rcx.java)

|

hi, I am sure Dario Laverde's RCX java API is based on RIS1.0. But the currently sold RIS version is 1.5. I want to use Laverde's RCX java API to control the robot made of RIS1.5. Is it possible? Any response would be appreciated. Yang (25 years ago, 19-Jun-01, to lugnet.robotics.rcx.java)

At least it runs. :-) That error means that for some reason install could not create the directory .lvi in your windows directory.
