Abb robots can encrypt modules, so they are not readable, but still executable. Abb's language is just as powerful as karel in my opinion.
Yes, Rapid. When you encode a module, and try to open it on the teach pendant on an abb, the pendant just states that the module is encoded, and not (human) readable.
Yaskawa has motoplus! Very powerfull language, it's C with Yaskawa library
KUKA is very similar to ABB.
Writing code in KRL (Kuka Robot Language), then use the official tool: KUKA.Encryption Tool, which will convert the *.src and *.dat file into a *.pfc file.
Differences between FANUC's *.pc and KUKA's pfc:
sample of *.pfc:
