By Fields Corrielus 2019-07-24 1794 0
This consumer-grade robot from the RoboMaster Mech Robotics competition features quasi-industrial hardware, a central processor with sufficient performance, 31 sensors, inductive armor that simulates skin touch, and a cloud with jitter control accuracy of 0.02 degrees Celsius Taiwan, omnidirectional mobile chassis.
These configurations make the RoboMaster S1's brain, sensory and physical performance far superior to similar educational robots, and a competitive "toy" that is highly playable and cool enough.
The RoboMaster S1 standard kit is priced at $699, and an expansion pack including the handle will be available for sale in the future.
This machine supports the design of custom accessories.
The assembly process is wonderful
The RoboMaster S1 standard kit has two upper and lower components and spare parts. When you open the carton, you first see four DC brushless motors and four McNamm wheel hubs.
▲ The top layer, DC brushless motor and Mecanum wheel are too exciting
▲ Set the lower components
If you have had your own experience of assembling a model or an omni-directional mobile chassis, then you should see the overall arrangement of the motor and the wheat wheel, the mood should be as ecstatic as receiving the Switch console.
▲ A well-prepared Mecanum round
But even if you haven't assembled the robot before, it doesn't matter. According to the illustrated instructions, after completing the 73-step installation, you will get a robot with omni-directional FPV driving, shooting experience, and visual recognition.
▲ The assembly tool is complete, the robot 1/3 of the fun in this process
It took us almost 3 hours to build the RoboMaster S1 from the parts into a complete machine. It also intuitively experienced that the material used in the RoboMaster S1 is quite solid and textured. The overall industrial design pays attention to detail and unifies the function and look and feel.
The picture transmission module is located at the top of the RoboMaster S1 and the camera is located above the transmitter with a parameter of F2.4/120° FOV.
The magazine is located below the image transmission module, and the button next to the magazine will automatically pop up. The officially equipped water bomb needs to be foamed 4 hours in advance, and the magazine can carry up to 430 water bombs at a time.
We smelled the water bombs before and after the foaming, and there was no smell. The water bombs will automatically degrade into powder after being fired.
On both sides of the transmitter is an infrared sensor, and the robot is equipped with induction armor on the front, back, left and right. In a multi-machine competitive game, when the water bombs inductive armor, the robot will automatically calculate the amount of blood left.
The motion controller and part of the line can be seen through the transparent housing at the rear of the S1.
Below the motion controller is the battery compartment, which needs to be pressed by the button of the rear armor to open. These details are quite good.
This should be a toy that many adults dream of
After the assembly, the RoboMaster S1 needs to be directly connected to the mobile phone through the "RoboMaster" app, or it can be used to connect multiple robots through the router.
▲ You can connect the phone to the handle, and the handle supports connection with the mouse.
In addition to mobile phones and tablets, we can also control the robot through the official handle. The handle supports connection with the mouse and keyboard.
On the phone control screen, the lower left is the dial and the shooting button that control the direction of travel, and the lower right is the dial and shooting button that controls the transmitter.
When we use the mobile phone to control the S1 to shuttle back and forth between the office and the outdoor floor, the Mecanum wheel allows the S1 to move in a very flexible and omnidirectional manner. With the two-axis pan/tilt and 720p 30fps, the mobile phone screen can achieve a good experience. FPV perspective.
The S1 supports somatosensory control with a maximum driving speed of 3.5m/s. In normal operation, one battery can be used for 40 minutes, and it takes about 1 hour and 30 minutes to fully charge each time.
When aiming at a target, the ballistic light can show a rather cool effect in dim light. When the magazine is loaded with water bombs, the water bomb can be launched at an initial speed of 26m/s, with a maximum transmission frequency of 10 rounds per second.
During the shooting process, the S1 can experience the real shooting after-sitting vibration, and the stabilization of the gimbal ensures the precision of the shooting experience.
S1 has the locking pedestrian tracking function also available in other consumer products in Dajiang. In addition, S1 can also record and take pictures from the perspective of FPV, to explore and shoot scenes and corners that ordinary people can't find.
In single player mode, the S1 can perform fixed-point shooting and mobile shooting challenges. The rule is that the robot must recognize the corresponding visual label in order to complete the lap, and the controller who first runs the specified number of laps wins.
In addition to the requirements of the controller to control the machine technology, this gameplay needs to be compatible with the machine vision capabilities of the S1.
S1 currently supports up to six machines for multi-player games. If you have two or more robots, the game will be a lot more fun. Based on the rules of the game and the sense of armor, the robot can open the "chaos mode" to attack each other, the game will automatically score according to the number of damage and the damage output value.
▲ Because there is only one machine, only the artificial attack armor can be manually tapped.
For example, the armor on the right side of the robot that you are manipulating is attacked. On the right side of the control panel of the FPV view, there will also be a red flashing response.
Multi-machine chaos mode also has random skills and custom skills, which can be created according to specific rules and scenes.
In the days when driving S1, it brought us the surprise: there is a feeling of moving the shooting game on the mobile phone from the screen to the reality, so that users can enjoy a high-altitude in the real world as they please. A fluent competitive event.
This can be flexibly controlled by mobile phones. It not only has entities on the ground in the real world, but also robots with many skills. It should be the ideal toy that many people (especially adults) should have.
How RoboMaster S1 implements educational functions
In addition to entertainment, the more important function of the Robo Master S1 is: education.
S1 supports both Python and Scratch programming languages. In the "RoboMaster" app lab, we can find the "Master Road", "Mechanical Academy" and "My Program" functions.
The "Masters Road" is a project-based tutorial that masters basic graphical programming knowledge from easy to difficult to learn preset levels, and enlightens the user's programming thinking through different tasks.
In "Master's Road", we found a teaching project called "Twisting and Counterattacking". In the detailed tutorial of the application, we can write a "Robot chassis and pan/tilt rotate in opposite directions." An instruction that allows the robot to reduce the probability of being attacked during combat.
When doing graphical programming learning, we can combine real-time FPV screen and parameter display, it is convenient to observe the running process of the program in real time and debug the code.
The Mecha Academy has detailed programming guides and video and video lessons that cover the basics of mathematics, physics, and programming, allowing users to get started with programming and robotics.
After mastering the programming knowledge, the user can try free programming in "My Program" and write a unique skill for S1. For example, writing an applause recognition command allows the RoboMaster S1 to recognize the applause and complete the corresponding action; writing the gesture recognition command allows the S1 to complete the customized action from the control interface after recognizing the human body "V" and the photographing gesture.
In addition, you want to use the different colors of the marquee effect, you can also program the settings yourself.
▲ One of the transformation schemes, the robot has the function of gripping items
The RoboMaster S1 has a total of 46 programming control components, 6 types of artificial intelligence programming modules, hundreds of programming modules, and 6 PWM interfaces. Friends who love robots and have strong hands-on skills should be able to play for one year.
Dajiang's understanding of education
Maybe adults will be attracted by S1's competitive gameplay, but the entertainment of this product is more for the robot education. The Robo Master S1 is aimed at the global youth and technology enthusiasts, aiming to let users from Gain knowledge in practice and exercise scientific spirit.
RoboMaster S1 is derived from the RoboMaster Mech Master Robot Competition initiated and hosted by Dajiang in 2015. For the competition to be a "business that is not profitable", Dajiang is a pure investment in the short term. It hopes that it can become a regular educational activity in the medium and long term, and the long-term goal is the spread of the engineer culture.
The introduction of the Robo Master S1 allows the first-time learners to learn in the entertainment, get the opportunity of programming and robot enlightenment, and enable users with basic ability to expand and create through custom programming and self-designed accessories.
In the letter from the S1 team to the first batch of users, they believe that this robot embodies the understanding of education in Dajiang:
True education should be free, open, and learned and tested in practice. Anyone should have fun in the learning process and, more importantly, gain unlimited confidence to explore the future alone.
I have to say that DJI is a socially responsible company, which is why I have been paying attention to and purchasing DJI.
In general, the RoboMaster S1 is a highly integrated technology in the field of consumer education robots. It has excellent hardware and complete basic functions. It is a real robot. What's more, it is fun and cool enough to drive users to explore the real world.
On this basis, it has carefully set up video courses and project tutorials, which allows beginners to explore and learn with interest, and has enough room to expand, allowing users to delve into the drums.
The emergence of RoboMaster S1 will greatly reduce the barriers for people to contact and possess competitive and educational robots. It is expected that S1 will gradually appear in the scenes of robot competitions and campus interest groups to inspire and motivate young people interested in science and technology. And more enthusiasts who are also interested in robots will find that "the opportunity is finally here."
