Each September as the new school year begins, many elementary school students are a little afraid of the unknown. Not only about starting school and the new people they will meet, but also about the journey they have to travel every day. They need to learn and remember how to navigate the world and the way to and from their own classroom. This can be made easier by a parent who is able to accompany their child for the first few trips back and forth to get acquainted with the route, often pointing to other interesting signs along the way such as, tall or bright houses or signs along the way. . Eventually it will be too small for the child to go to school and remember the process. The child will have developed a mind map of the world and how to navigate it.

Starship Technologies offers the best way to deliver miles with sidewalk robots that travel around the world every day. Our robots have finished shipping more than 100,000. To move from point A to point B, the robots have to prepare for the front end that also requires a map. While there are many public mapping options such as Google Maps and OpenStreetMaps, they are limited in that they are designed with the flow of traffic in mind and only focus on creating traffic maps. Since robots can travel on the road, they need accurate maps to show where it is safe to walk and where to cross, just as a child needs a map of how to get to school safely and on time each day. How are maps made?

The first step in mapping the return robots is to explore the landscape and create the first map (2D map) on top of the satellite images such as simple interlocking lines representing traffic (green), crossing (red), and driving directions. (purple) as shown in the accompanying picture.

The system uses the map as a graph of the node and can be used to create a path from point A to point B. The system can detect the shortest and safest route a robot can take and calculate the distance and time it can take. to drive this process. The advantage of this method is that everything can be done at a distance before any robots arrive on the scene.

The next section involves showing the robots what the world looks like. Similar to the illustration of a parent with a child, robots need to hold hands briefly the first time they search a location. When the robot launches its course, a host of cameras and surveillance cameras gather information about the world around them. This includes thousands of lines that come from the edges of various objects, for example houses, electric poles and roofs. The server can create 3D world-wide offline maps from these lines that the robot can use. As a child, the robot now has a model of the world with control notes and is able to understand where it is at any given moment.

Since our robots have to put different locations at the same time to complete the whole mission, for the various maps to work properly they must be connected to form a single 3D map of a given area. Collaborative maps are gradually created by plotting the various sections of the new space until finally the map looks like a complete finished image. The server will put the maps together based on the data the robot originally collected. For example, if the same roof was detected by two robots, then the program calculates how it connects to all other maps. Each of the black lines in the diagram below represents one section of the map that has been added to the map.

The final stage of mapping, before the robots start to drive on their own, is calculating the location and distance. This is done by editing camera images captured by the robot looking at the site as a guide and combining pre-designed 2D maps to capture satellite images.

At this point more information is added to the map to better define the safe areas for robots to navigate.

Indeed, the world around us is far from stable. There are daily and seasonal changes in movement, construction and renovation, which change the way the world looks. How would this affect the location of robots? Basically, robotic programs can change slightly to the center of a well-mapped map. 3D models are solid enough and full of large amounts of data, so a log cut here or a single house that was demolished there would not be difficult for a robot to show where it is or to use a map. And, in addition to that the robot that operates on a daily basis continues to collect information that is used to change 3D maps over time. But if the site is rebuilt, or new roads are built, then the answer is simple. The map needs to be updated using the latest robots collected. Then, the other robots can move steadily in the same position as if nothing had happened. Keeping current maps is essential for robots to operate efficiently and independently.

As you have doubts so far, I love playing with the ideas of 3 dimensional space. Ever since I started playing the first 3D computer game (Wolfenstein 3D), the 3D world in digital format has fascinated me. I wanted to create my own 3D world of computer games, so I found ways to modify existing games. Later, I also tried my hand at 3D computer modeling, which I found interesting. With the popularity and acquisition of 3D printers, I also began to print material. But long before that, during recess in the summer, I often made paper models of various houses and cars. It was an easy and inexpensive way to make something with my own hands, yet it was also fun to see how the 2D design on paper, with a little cutting, polishing and gluing, can be transformed into a 3D model. Basically, making a 3D object or “discovery” paper is, in a way, different from a map. It creates a 2D shape on top of a 3D object.

Since I was interested in paper making I decided to design our own Starship delivery robots. The purpose of this model is to allow others who can enjoy the passions I make to create our own delivery robots. Making a paper model is a fun challenge, and once in a while it makes for a great decorative item. Similar to the design of 3D robots, the design of papercraft requires precision, precision, and precision according to the way all parts interact. Also good patience.

I have recommended you to design your paper delivery robot and I want to see your efforts. Enjoy and have the opportunity to make your own paper robot!

Please post a picture of your robot on Instagram and post @StarshipRobots to find them!
