Human-Robot Interaction is envisioned as a technique for remote access for on site excavation and landscaping. This is a solution to translate 2D user inputs into systematic set of instruction for the machines to execute.


Step 1 : The process initiates with a skilled individual drawing a closed curve shape on a sheet of white paper. To capture this activity, a camera is utilized, which then streams the footage to a computer via a reliable USB or Bluetooth connection.

Step 2 : Once the video is recorded, the Python code reads it, removes any distortion, and subsequently outputs the contours of the shape drawn. To create a digital representation of the curve, numerous points are extracted from the contour and sent to Grasshopper using a UDP connection. Once the data reaches Grasshopper, a script is executed that automatically interpolates the curve and performs a fill operation digitally.

Step 3 : After the filling geometry is created, it must be converted into a set of instructions that can be executed by the robot. This is achieved by creating a connection between Grasshopper and Machina Bridge, which then connects to the robot. Once the connection is established, the set of actions required to create the design are transferred to the robotic arm, which subsequently executes them with precision and accuracy.
