What should we make?

Machine Design Week was a time to make the machines we needed ourselves.

First of all, we had time to think about what we wanted to make and what we could make.

We had a lot of good ideas, but we decided to build a drawing machine where we could draw pictures on the wall.

We found a good tutorial while looking for a machine that could draw pictures on the walls of the Seoul innovation Fab Lab entrance.

We decided to design a simple installable drawing machine here.

We decided to work in teams of hardware and software for efficient work.

Team hardware

Hyunho simply sketched it and I designed it again using Fusion360.

Tested the drawing machine frame that finished the design using a laser cutter.

It doesn't look bad, but the joint was so weak that there was a problem with the coupling.

Modified the joints and changed some of the designs.

And again, we tested the design using laser cutter.

GOOD..!

After the design test, we started making real-size frames using the shop bot.

The frame was strong for back and forth shaking, but weak for left and right shaking. a slight regret

The frame reinforcement was needed because the motor could be shaken when operated.

The frame reinforcement part was made using the shop bot.

The frame-reinforced shape has also become stronger in shaking the left and right sides.
