Thanks to everyone who helped this year’s Maker Faire Bay Area be so special! We are looking forward to seeing everyone next year and are already improving our show. Below is a photo our booth before the event started. It is hard to believe over one thousand people visited us over the course three days!
Want to see how our autonomous robots experienced Maker Faire Bay Area? Check out the video below, generated based on the stimuli, emotions, and actions of HipMonsters’ two robots over the course of three days at the Maker Faire.
The robots recorded the following sensory data:
💙 Noise: A sudden, loud noise. Represented by the color Blue.
💚 Distance: Motion within 1 foot. Represented by the color Green.
🧡 Movement: Motion within 6 feet. Represented by the color Orange.
💛 Speech: The spoken word “robotics”. Represented by the color Gold.
💗 Touch: Contact on the touch sensor. Represented by the color Pink.
🤖 Frequency of Stimuli: How often or rarely the robots received stimuli. Captured by the Movement of the cube.
🔉 Mood: Happy or overstimulated. Reflected in the choice of Sound.
Turn up the volume of the video! It’s not music you’re hearing, but the robots’ moods given the stimuli.
Since we engaged the Touch sensor at the end of each demo, this means we ran 420 complete demos over 3 days. Our robots have been well socialized!
When designing Robot Freedom, our educational presentation on robotics, the HipMonsters team wanted to make robotics and artificial intelligence (AI) approachable to a mass audience in hopes of inspiring the creators within all of us. To achieve this, the core principles for our AI design were defined by the Hip Monster’s sister team (ages 9 and 12 at the time), namely, robots should have distinct personalities, emotions, curiosity and be first and foremost pieces of art.
Given these principles, the foundation of our artificial intelligence framework (show above) is based on Stimulus Organism Response (S-O-R) Theory. S-O-R theory is a psychological framework that enables researchers to explore how stimuli (such as a bell) can impact an organism’s responses, (a dog salivating). Like Pavlov’s dog salivating at the sound of a bell, our robots learn and adapt as they experience outside stimuli and are always eager for more. The robot’s AI is driven by five personality traits that govern how they interpret and respond to stimuli. Below is how a signal from a sensor (stimuli) flows through our AI (organism) and results in an action (response).
Central to the robot’s stimuli exploration is a sensor array of ten sensors ranging from sound to touch. When a robot receives a stimulus, it first processes the information based on its preset personality, then uses past experiences to choose a response based on its personality. Below is a color key to the robot’s sensor display panel.
These experiences are weighted based on the outcome of the robot’s actions allowing the robot to adapt responses to new stimuli. The robots can move, change visual effects, or talk using a chatbot. Below is the full software stack used in our robots.
We are delighted to say the Hip Monsters will present Robot Freedom at the this year Bay Area Maker Faire!
Robot Freedom is a celebration of robotics and steampunk designed to teach kids of all ages the basics of robotic design with fun hands-on demonstrations presented by an autonomous android powered by feelings. See how a mechanical mind works, power a music robot with your own strength, and watch how a robot sees a world filled with stimuli!
The HipMonster.com’s team was invited to do a middle school robotics presentation last month to show kids the fun side of robotics and technology. The audience was so awesome and engaged making it a fun experience for everyone.
The theme was how to take over the world using robots, making it fun to keep the students engaged. We used a steampunk template for our slides to match our robot designs and channeled Girl Genius when presenting.
Testing the controllers
The robots got banged up a bit in transport, but nothing got completely broken. The biggest issue was the wires getting pulled out from the Arduinos. Luckily, it was only the breadboard jumper wires which are easy to put back in place. None of the soldered wires were broken which could have been very hard to fix. Breadboard jumpers are designed to be repeatedly taken on and off. They are like tiny colorful USB cables which helps see how what each cable is connected to (this is important because sometimes you can have dozens of wires). When you solder a wire to a controller, it can only be broken to be removed. You solder wires by using melted metal called solder and a really hot device to melt the metal. When a solder connection breaks you need to melt the metal again to reattach.
Fixing the wiring
Here we are putting the finishing touches on Number Two and Number Three. All the robots traveled well and were up in running in thirty minutes except for one whose battery was faulty. When transporting batteries, we take extra care not to damage them and use a special carrying case.
We wrote a quick intro for the robots to perform to set the mood. After the intro, we dove right into robotics.
Here are three robot bodies. The first is Number Three. She can move her arms and hands, and talk. The middle is called Number Five. He can walk forward on his own using his four legs. The last is Number Two. He can’t do much, but he can still talk and move part of his arms.
All the robots lined up in the gym
For each robot body, you need to do several things. There needs to be a skeleton, a power source, and something that makes the robot move. When we are thinking of designs for our robots we often think of animals that already exist. We also take inspiration from robots in different books and webcomics.
Presenting to the school
Number Four is the most complicated one. It took us over one year to build her, and she is still being modified. Many other robots were also not built all at once but were gradually assembled as we got new ideas.
After you build the body, you have to give the robot a brain. in our robots, we use something called an Arduino.
It is basically a tiny computer that you can program to do different things. For our robots, we use Arduino to make the robot walk on its own, so we don’t have to use a remote control. For one robot, the Arduino can also choose the direction that it walks in, and how fast it walks. You can find a simple example here.
We code the Arduino from our computer, then the Arduino sends messages to the robot to control it. We edit the code based on our observations and new ideas.
We have many different types of robots that can move their whole body, each type demonstrates a different way of moving. We have the 4-legged walkers, which are our first moving robot design. They are made of metal pipes and have four legs and wheels for feet. We put wheels on their feet because we wanted less resistance and friction, but we didn’t want the robots to just be like a remote-controlled car. We wanted them to walk. The design of the legs and the “knee” has made a big difference.
Another design is our Seal robot. This one is very different, as it only has two legs and no wheels. The legs pull themselves forward, powered by linear actuators. To make sure that the legs don’t just go backwards and stay in place, we put wedge-shaped bits of foam at the bottom of the seal’s legs. When the seal moves forward, the wedges give no resistance, but when the legs pull back, the wedges stop them.
The next robot is our Bunny robot. The bunny robot is also unique because it was originally designed to hop. The two back legs push it forward, thanks to the springs. This one is powered by air and pistons, so you can get the sudden jolt that is harder to achieve with linear actuators. This robot is also one of the only robots made mostly out of wood. We took the idea for the legs from our wooden toys.
This is the Kangaroo. The kangaroo’s main difference besides the number of legs is the feet. The feet are small animal toys, designed to only go in one direction so they can move forward more efficiently. The back leg powers the whole robot, and we used linear actuators.
The last robot is the Mouse. The mouse is just a broken blow-dryer attached to wheels from some old toys. It is very simple, so we decided to make it walk on its own, completely uncontrolled and completely randomly, controlled by the Arduino. You can see the code here.
The mouse in action
Sorry, this photo was blurry, but the mouse was super fast that day-well charged batteries.
We want to give a big thanks to all who came to our robotics presentation, and everyone who helped and supported us! this was our first big presentation, and we couldn’t be more happy with how it turned out!
Girl Genius is a webcomic started in 2002 written by Phil and Kaja Foglio and colored by Cheyenne Wright about a world of steampunk mad scientists that build amazing robots. Girl Genius has greatly influenced our art and writing and we recommend you read it. You can read it for free online, or buy physical copies. The authors write a new page every other day, so if you get to the end, make sure to look back to find new pages.
Trilobites are the Heterodyne family sigil (the Heterodyne family plays a central role in the story) which is a fitting symbol of the old and mysterious family.
What we like most about the main character Agatha Clay is that she is really smart and hilarious. She builds lots of cool inventions that do amazing things, and since she thinks differently than the other characters, her dialog is really funny. Our favorite quote is, “But I want to do math now!” Some of our favorite inventions that she had made are a coffee machine that makes coffee so perfect it makes people go mad, a deer robot that looks really pretty but has a bunch of different types of weapons, little circular robots that can make other robots, and a weaponized wagon army controlled by an pipe organ. The fact she is also very dangerous just adds to the fun!
The artwork is fantastic and really brings to life the rich world of Steampunk Europa. What is most impressive is the attention to detail, for example, there are sometimes little monsters on the page, and you have to look carefully to notice them. Also, the steampunk robots look like they can actually work! There are also lots of scenes that are happening in the background, so look carefully, otherwise, you might miss some information! In the beginning, it is black and white, but most of the story is in lots of colors.
Each location is rich in details and lets the reader explore a steampunk world like no other. Our favorites are a huge underwater city buzzing with lots of steampunk submarines and Mechanicsburg, the home of the Heterodyne family which is packed with danger, mystery and dominated by the powerful Heterodyne castle.
Girl Genius comics
The plots take unexpected and fun detours but everything is intertwined, all the characters are somehow connected to each other, and there are no loose ends. The dialogue is hilarious and rich, for example:
Violetta, “So, when can we be sure it is done and we haven’t doomed the Earth?”
Agatha, “Oh once the containment limit returns to normal. As for not dooming the Earth- well- that is more a lifelong goal, really. But so far so good.”
Humongulus: Humongulus angry? Never! You have used guile! Tactics! Awareness of the landscape! Humongulus is impressed!
Franz: Good ’cause with those arms you could punch me into next week.
Humongulus: You know the very sole of Humongulus.
And it is not just us who thinks Girl Genius is great, it has gotten multiple Hugo awards!
The Hugo Award!
The best part of the world is the crazy robots and monsters. There are lots of weird monsters that just live alongside everyone else, and crazy robots are an everyday sight. The robots and monsters are central to the story and some are main characters who act and think very differently than humans which adds to the realism.
Our favorite little clank
This is a picture of a little clank (robot) that the main character made. Girl Genius is in a steampunk world and has cool robot illustrations. We were so inspired by Girl Genus’s cute and cool-looking robots, we spent two years designing and building our own working steampunk robot Number Five !
When we visited Maui this year, we found an awesome chocolate plantation, Ku’ia Estate Chocolate. They grow delicious world-class cacao trees (where chocolate comes from) on land that was made useless due to sugar plantations. When the land was used to grow sugar it was stripped bare of trees, the crop was never rotated and tons of chemicals were dumped on it turning the once lush land into a desert. You are read more about Maui’s effort to restore the land here.
This is what the chocolate farm looks like from above. It is located in Maui on a plot of land that is reserved for agriculture. It looks like an oasis in the desert created by the sugar plantation. Ku’ia Estate Chocolate needed to replant the tropical forest that was once there to block the wind and the hot sun (cacao trees love the shade). They also had to do a lot of work to get nutrients back into the soil making sure to use organic farming methods.
The chocolate starts its life as a tiny flower. They are very delicate, so the wind blockers are extra important to ensure that the flower doesn’t get blown off the tree. Since they are so small, the only insect that can pollinate the cacao plant is the chocolate midge.
The flowers turn into cacao pods. They are ready to harvest when they turn a darker color and get a lot bigger. You harvest them all year round, but the biggest harvests are between May and July, and between October and March, after the rainy season.
These are the Cacao trees. The pods grow on the trunks and thicker branches of the trees because they are very heavy. The trees are currently pretty young because Ku’ia Estate Chocolate hasn’t been around for a very long time.
After the cacao beans are harvested and prepared, they are put through a series of machines to create all the different chocolate creations. Ku’ia Estate Chocolate grows their banana leaves to use for the preparation process, making them more self-sufficient. They also don’t take away any of the natural flavors of the cacao beans, so the chocolate is more nutritious and has a complex flavor. They do shipping so you don’t have to go all the way to Maui to get their chocolate, but going to their cacao farm is a cool experience.
Ku’ia Chocolate has created a whole bunch of unique flavors that they sell in their store, like orange mango guava, lemongrass, and calamansi lime, so you are sure to find a flavor that you love. They even grow the fruit that they use for their flavors on site and it is very fresh.
They also have dark chocolate, milk chocolate, and even dark milk chocolate. Dark milk chocolate is smooth and creamy like milk chocolate, but has a high cacao percentage, making it rich and flavorful like dark chocolate.
Ku’ia Estate Chocolate after only three years of selling has won the 2021 Cocoa of Excellence Gold Award for the Asia Pacific region and the 2022 Good Food Award. They give all of the profits that they make to local Hawaiian non-profits.
There are also tours of their plantation (which we highly recommend) that teach you about the process of making chocolate. The tours end with a chocolate sampling deep in the cacao forest.
Is it so wrong I keep thinking about chicken and waffles after just one random encounter at Little Skillets? The chicken was so tender they must have been raised in some beautiful land where a hug is given out for free, waffles so sweet I strongly suspect they did something unnatural, not to mention illegal in most states, with donuts and drinks so stiff years of yoga would still make their downward dogs look like a plank. I sit in bed conjuring up the memory of piles of food before me with a burning drinking making it ways down my throat and wonder again and again, “Is this wrong?”
Grub is the foodie hub in Mission. Causal with home style meals it is a special start to the day. Proportions are large so perfect for sharing. The endless mimosa are refreshing.
