msgid "Remote control a slave robot without using an <a object|exchange>information exchange post</a>. The robot should pass over the 6 blue crosses. You must use a <a cbot|string>string</a> to pass the orders to the slave bot. This string contains the order the slave shoud execute, for exemple <code>\"move(20)\"</code>. You can see that this is the same syntax as used in the CBOT language but we could have chosen any other syntax for exemple something like <code>\"advance=20\"</code>. The string will be a <code><a cbot|static>static</a></code> class member that will be used to communicate from the master to the slave."
