So the very first day went by planning to make a machine which would enrich our understanding of the machanisms involved in machine working, how it should function, its axis, the components involved, the loads it needs to take, the materials available and most importantly doing the most basic activities in a variety of ways. So finally we decided to make a Wood Carving Machine, which includes X Axis, Y Axis and a Rotating table. While the discussion would take place, i took the lead to keep sketching our solutions to try and narrow down the ideas to as many pragmatic forms as possible a few of those sketches shown below. for each sketch, we collectively figured out its possiblilites like positions of axis, function, and how to hold the workpiece, choice of spindle, press fit designs, gap between bed and spindle, how to set machines origin,
Outcome of this week:
OUR GROUP WENT ABOUT FIRST MAKING 1 MACHINE COMPLETELY BY HAND AND POWERTOOLS AND ANOTHER LATER ON ON DESIGNING. THIS WEEK WAS SPENT MAJORLY DOING EVERYTHING BY HAND WITHOUT CAD Initially to test out things manually. From the fabricated mechanism , we then arranged for digital version of it with Jatin taking a lead in modelling the design we made in solidworks.THE NEXT WEEK WILL BE ABOUT MAKING A PROPER ALTERNATE MACHINE THROUGH DIGITAL FABRICATION INCORPORATING OUR LEARNINGS FROM THIS EXERCISE.
WEEK'S OUTPUT
This video was compiled by me to showcase how we went about making the machine by hand first ensuring we understand each mechanism. Much more was done than being shown.
Video showing us trying to understand Mechanics behind different Machines(My hand is the one with the watch :p)
Stop Motion i made for our thought out machine's working using sketchup's sketchy filters
Started assembling a simple machinee to test out the working
Manually trying to operate it
Time lapse of proof of concept machine
Experiment with firefly as controlling medium for the machine
Am a little unsure about the possibility of using firefly to control the motors but nevertheless thought to try this interesting concept of 3d softwares controlling electronics for my personal learning. The servo moves but I think i have to start thinking about another way to control the machine probably since Nishtha and i have taken the responsibility of figuring out the working of the machine's electronics and programming.
Following are the steps to connect a servo motor to the Arduino:
The servo motor has a female connector with three pins. The darkest or even black one is usually the ground. Connect this to the Arduino GND.
Connect the power cable that in all standards should be red to 5V on the Arduino.
Connect the remaining line on the servo connector to a digital pin on the Arduino.
We were given lectures on 'C' at Vigyan Ashram from externals and other peers experts in C @ Kochi, Pabal and Pune.
