Build Stand is a platform on which there is a baseplate to build on. Using the Lego MINDSTORMS EV3 and the Amazon Echo you can command this platform to tilt or rotate as you need as you are building. Ldraw, PDF, alexa skill and python code are provided. Up, Tilt Up, Down, Tilt Down, Right, Tilt Right, Left, and Tilt Left are commands to tilt. Rotate/Turn Right and Rotate/Turn Left are rotational commands. different preset commands include Tilt And Turn Left/Right and Circle. I will comment as soon as the alexa skill is available.
