#1 Robots can't be picked up due to typo

The robots can't be picked up due to a typo of cliker instead of clicker.

Ordinary robot

AsyncErr: Lua: Runtime error from mod 'rob_opr_base' in callback luaentity_run_simple_callback(): ...ad/.minetest/games/rob_opr/mods/rob_opr_base/robot_1.lua:97: attempt to index global 'cliker' (a nil value)

Objective robot

AsyncErr: Lua: Runtime error from mod 'rob_opr_base' in callback luaentity_run_simple_callback(): ...ad/.minetest/games/rob_opr/mods/rob_opr_base/robot_2.lua:101: attempt to index global 'cliker' (a nil value)

That's a shame. I don't think I can fix it until after the judging is over. Thankfully you can also punch the robots to pick them up.
