Mx Robot’s Sensor Pack

Today’s Topics!

Robots need sensors to gather data and hopefully not harm their environment. Mx Robot will have quite a few and I’ll explain why I choose the ones that I did. Why the ‘Mx Robot’?

Why Do Robots Need Sensors?

Robots need sensors in order to gather data about their environment and various parts of themselves. Such things as not running into walls without harming the environment and the entities that share it with the robot is important. Also being able to sense the remaining battery life so that the robot can use that data to either go charge or complete it’s next task is very important to the battery health and the mental health of the human that is associated with it. If your robot is knocking stuff over or destroying your things, it’s not really an asset to you. Sensors provide the data and the robot’s code interprets the data according to how it’s programmed. The types of sensors that you use in your robot just as important as the code that interprets their data, one is only useful as the other.

Sensors For Mx Robot

So what sensors have been chosen and why for the robot? So far, I really don’t have a hard list of tasks Mx Robot to do. Some ideas have been nightly patrol and getting a can of soda from the fridge, perhaps an individually packaged snack from the pantry. These are lofty goals and will require a lot of coding and robot designing to accomplish, so starting off with a generic robot and letting things go from there, but sensors are very important no matter the tasks the robot will be doing, especially since it’s not in a closed environment by itself.

Working from front to back and looking at the insides of the bot. The line following module is in the very front, it’s primary use will be lining up the robot to it’s charging base. Working back a bit, there will be two SR-04 sonar modules that will be providing data about any obstacles in the front and to the sides of the robot. The back end will have two IR pairs for object detection for obstacles behind the robot. Internally, there will be encoders on each drive shaft, an accelerometer and gyroscope package, and voltage sensors on the batteries. As you may have surmised already, most of the sensors are devoted to keeping the robot on it’s path and away from obstacles, thus far.

Should Robots Be Genderless?

I’ve been thinking about the current times and all the changes taking place, plus how sexist things are, which has started another set of thoughts altogether. Why do we consider robots to have one gender or another, is it wishful thinking or just the norm? Industrial robots probably shouldn’t have human names, but something made up of letters and numbers to identify them, because saying,”Leroy’s connectors need some jingling” would be awkward and the resulting comments probably would get some people fired(Me).

One of the issues that I foresee about assigning gender to a robot is that it may be programmed to act in the society norms of that gender and either allow itself to be abused in some way or be treat humans of the opposite or same gender as norms of the society it is in. Some would argue that having gender would make the robot more acceptable by humans, but I find that to be a sexist excuse to keep spreading those sexist views and not something that would engender good feelings in the long run. Androgyny should be the go to for most robot designers, this is the 21st century and we should as a society grow enough to accept all genders and treat people and machines with respect and not force our own views onto others

That is why I changed Mr. Robot to Mx. Robot, to reflect that it should be accepted as genderless, not a threat to anyone and that it is here to assist within it’s limited capabilities.

A Rather Busy Week

Progress and Such

It’s been a rather hectic week, trying to get enough dry goods to last for awhile and get some work done on a few projects, has been quite challenging since it’s getting hot and going into any store requires a mask. Both even together are not bad, but combined with humidity, it does complicate things, quite a bit. Plus, doing the exchange of effort for monetary gain was a good thing, as well. Most can’t wait for things to go back to the good ol’ days, but I’m beginning to believe that they are gone for good and this is the new normal. By the way, feeling much better than last week, was out and about in the heat a bit too much, I guess.

Off to more fun topics, though. Mr. Robot has tracks and a chassis now, and the hydroponics mini lab is coming along fine.

Mr. Robot Has Bod!

Got another track set made and sealed the ends and the chassis modified and printed. I found the 6V-12V motors that will fit in the Tamiya Dual Gear Drive kit and the Line Follower kit came in, as well. So, just need to hook those to an Arduino and a Dual H-Bridge for the coding to begin.

Mr. Robot's grey tracks and orange chassis

Plenty of internal storage for things like battery banks, the line follower kit and the dual drive motor kit, and maybe a few small sensors. This coming week, I’d like to get the battery banks done, at the very least designed. I’ve gone with this particular layout, because it’s quite modular and when I change or add things, I don’t have to reprint an entire chassis and such. This is very much a rough draft.

Hydroponics Laboratory Update

Got the base done last weekend and let it dry completely outside for a few days, it came out rather well since I’m not a great carpenter, mediocre would be a better term for my carpentry skills(smile). I did mount the stand on it, hung the grow light and put the seedlings under it. I had tried a method of growing the seedling using a compact fluorescent light, but they really did not take to it, very well.

It may just be my lack of skill, or too much water or something else. It looks like the kale, cherry tomatoes and the marigolds made it, though. It was not a complete failure, I should water less and use a grow light for seedlings, especially for indoor hydroponics. I’d thought of putting it outside, but figured that the heat would have destroyed the seedlings’ chances altogether.

DIY grow tent out of mylar sheeting to reflect back the light from the grow light for the plants to absorb

The frame was mounted on the base, and the next experiment is in progress, which is the grow tent. I did tape the mylar sheeting to the outside of the frame, and it’s not entirely transparent, but let’s just say that my living room has a creepy purplish glow to it in the evening till the timer shuts off.

Some future goals are:

  • Wash the hydroton
  • Set up a way to measure the water/nutrient level of the reservoir
  • Print the venturi tube for the pump system
  • Upgrade the frame to thicker tubing
