MicroRobots

Day 1: Introductory Class

To start with, I took this course because I didn’t have any knowledge about electronics at all. And sensors are something that could be inculcated in a lot of products and would also help me further in designing products. So on the first day we built a tiny robot of our own with a motor, battery and battery holder, switch and wires to complete the circuit. This was the first time I actually made a circuit on the PCB board and soldered it. First when I tried to solder, I found it a bit easy but later I realized that it has a particular technique. The soldering iron should be placed on the board first at a certain angle then the soldering wire should be held while it melts on the required place. I had a difficulty while soldering the motor because one of the legs broke when I switched on the motor. So the solution was to neatly solder the leg back but I couldn’t do so since I didn’t know where exactly I had to place the leg. So I took Shreyasi’s help for it and learnt how to solder it back. After all the connections were made, the robot worked perfectly fine. To make it move, we used U-pins as legs and balanced the robot. I was very fascinated by the way it moved. Also, everyone’s robot moved differently depending on the way they fixed the legs.

Day 2

As soon as we entered the lanes, all I could see was electrical shops. There were so many of them and they had almost every electrical component. When we reached Vishal electronics we realized that it is a very busy store and people kept coming and going. There was absolutely no space to even stand. It took like 5-6 hours for them to get all the things from the list and then count each and every component and then negotiate. It was interesting to see so many types of resistors and capacitors, sensors, tools, etc. I had no idea that an electrical shop would be so crowded. There were so many other electrical shops next to each other and to my surprise they had a good rapport with each other. It was really exhausting to just stand there and keep checking. But they patiently got each and every component, although they had to attend so many customers at once. It was a different experience to look around and understand how things worked, but very exhausting and irritating at a certain point.
