//AGENT SIMULATION 1.0 AGENTS PARAMETERS 1.1 SINGLE AGENT SIMULATION 1.2 MULTIPLE AGENT SIMULATION

The aim of the workshop is to generate local rules that modifies the behaviour of the agents and engage the agents real time with the CNC (Computer Numerical Code)and to obtain a feed back loop. The criteria is to make the mill respond according to the local behaviour of the agent in real time.

SPECIAL BEHAVIOUR CNC REAL TIME

Our workflow starts on exploring local behaviour of agents simultaneously with single agent and multiagent . In regard to CNC milling , real time feedback is achieved through kinect. Milling multiagent simulation as a surface and single agent behaviour on it changed the morphology of the surface with the feedback from kinect.

We encountered this problem as the pre position and current position was not updated.

So the drill would not lift up and go to the next space rather drags to the next position.

Our strategy is to change the morphology of the surface simulated from multiagent by the interaction of single agent with the kinect . The single agent varies depth according to the feed back from the kinect.

5.1 KINECT TESTS

ARDUINO and PROXIMITY SENSORS are tested first to detect the distance reflecting on the brightness of the image. But it detects distance point to point rather than the entire surface. So arduino and proximity sensor is replaced by KINECT.

5.2 KINECT SET UP

5.2 KINECT SET UP ISSUES AND OPTIMUM SOLUTIONS The problems encountered with the kinect sensor were the

-Angle -Distance -Resolution of the kinect.

The appropriate distance for the kinect to have the best resolution was 75 cm from the machine bed.

The most effective angle for the kinect to be placed would be parallel to the machine bed, so as to enable it to give a top view of the surface. However, since there was a definite possibility of the frame used to hold the kinect, colliding with the CNC drill, the frame was restricted to a 120 degree angle from the machine bed. and also the ‘Z’depth of the CNC.

5.3 REAL TIME CNC MILLING

Kinect reads the topological information and the data is passed to the agent simulation so that the Z depth is updated accordingly. At the same time, drill bit of CNC is following the same path of the trace of the single agent (yellow trace) affected by the single agent generating new morphology of the surface.

5.3 REAL TIME CNC MILLING ON THE SURFACE

TOPOGRAPHY CHANGE Real time milling with sensor feedback loop changed the original topography. There is a continuity of toolpath on the original surface.

We use V Bit 32mm which is same with the image milling because this drill bit is big enough that can actually change the topography, then give the kinect different input constantly.

Because of the difference origin between CNC and Processing, the output from CNC is mirrored.

Drill bit blocked the visibility of the kinect.
