Week 5 - Journal

I wanted to make something that does an autonomous action, and I am always interested in such bots and robots, so after a bit of searching, I found this drawing bot to be cool, so I decided to make something like it.

Simulation

In Tinker CAD, on a small breadboard, I connected the red LED with the resistor and made the resistor value to 220 ohms, then I connected the DC motor with the previous branch, one terminal with the negative of the LED and the other terminal with the resistor, to make the connection parallel to be efficient.
After that, I connected the push button, one terminal with the motor and the other with the negative of the power source.
I connected the positive of the power source to the same node where the motor and resistor are connected.
I made the voltage source to have 5 volts output and 2A current.
You can find the circuit Here.

Testing:

I made the body of the robot using a Pringles' cup and 3 markers with the motor on top of it and fixed it using double-faced tape and with the circuit

I connected a pencil rubber to the motor's shaft to make the robot move.
I connected the 5v adapter and it worked

Implementation:

After making sure that it is working, I removed the markers' cover and then put it on a marker board and connected the 5v to make it move.

Problem 1: wiring size

The jumpers were quite large in size and were making the bot stop

solution

I used smaller wires to do the connection

Problem 2: the material

I had a problem with the material cause I first used a a tea cup from cardboard and a paper cup but it couldn't withstand the weight of the pens, also the pens were ubalanced.

solution:

I used a pringles cup.
