If I mount this module on my Standard Mechdog robot dog and give it a command, like, "Robbie sit", can I program in Wondercode to let the robot dog actually sit? I ask this, because I see in Wondercode, with this echo module, all the WonderEcho module speech command type word lists are only showing Chinese lists. I do not see an English list.......
Hello customer,
The MechDog is compatible with the WonderEcho module, and we have updated some built-in programs for it.
If you’d like to create a program that makes it sit when it hears your command, please refer to the tutorial here:
