It is believed that for most boys, owning a robot toy is definitely one of their childhood dreams. With the rapid development of intelligent robots in China in recent years, humanoid robots have gradually entered our lives. The well-known Leju in this field has launched the popular AELOS robot, and now they have made persistent efforts to update the new generation of AELOS 1S. Let's see what's outstanding about it.
Appearance/design
The overall outer packaging of Leju AELOS 1S is mainly white and gray. The handsome product pictures, striking product names and the product positioning of "Intelligent Humanoid Robot" constitute the whole content of the picture. It is simple and bright, while the sense of technology is outstanding. The product pictures displayed in the "superhero landing" posture on the front are even more impressive.
The back and side are very conventional brand logos and product parameter logos. On the whole, the packaging of Leju AELOS 1S is more in line with the current trend of electronic products and more fashionable and simple than the previous generation AELOS.
After opening, you can see the body of AELOS 1S. The chest, head, hands and other parts that may be worn with the packaging are protected with plastic film to prevent damage during transportation.
The accessories are the same as the previous generation AELOS, and the warranty card manual, charger and microUSB data cable are three samples, of which the accessory charger output power is 8.4W (8.4V/1A).
The overall design of AELOS 1S basically follows the design aesthetics of the previous generation product AELOS. The main reason is that the details of the back design have been further optimized, which makes it more beautiful and improves the integrity of the back of the body. As a humanoid robot, AELOS 1S is subject to the actual conditions, and naturally does not have those cool shapes in science fiction movies or animations. However, the design of AELOS 1S can be regarded as one of the best in the current humanoid robots.
AELOS 1S also inherits the strong and durable characteristics of the previous generation of products. In terms of materials, it still uses the combination of aluminum alloy+PC/ABS. The joints and skeleton are made of aluminum alloy to ensure firmness and durability. The body and shell of PC/ABS reduce the weight as much as possible.
The biggest change in the appearance of AELOS 1S is the shape of the back. The original power button is integrated on the back, and the functions of switching on and off, emergency stop, and reset are integrated. Different functions can be switched according to the length of the key time.
The speaker is still placed behind the head, consistent with AELOS.
The waist only has a charging interface and a microUSB interface for burning, which is more simple and beautiful than AELOS.
In addition to the words of AELOS, there is an indicator light below the chest to remind the user of the different states of AELOS 1S.
As a humanoid robot, it needs to be close to human in joint activity to imitate human actions. According to the data provided by Leger, the steering gear of AELOS 1S can move 180 degrees within the allowable range, but in order to simulate human actions, some joints or restrictions are made; At the same time, Leju said that there is also a 270 degree movable steering gear. Considering the control accuracy, it did not equip AELOS 1S, but chose a more suitable 180 degree movable steering gear.
In the actual test, 180 degrees of movement can be achieved at each important joint, such as the shoulder joint, knee joint, elbow joint, hip joint, and so on. Actions such as "line horse" and "side roll" are not a problem. The special one is the ankle joint. Because of the firmness of the foot and other reasons, the mobility is not as good as other joints, but the ground of the foot is good and can provide a good point of force.
As an aside, it may be because of the high mobility that Leju has set the product label on the crotch of AELOS 1S (laugh).
The excellent mobility allows AELOS 1S to pose in a variety of positions. It's no problem to kneel on one knee and perform such difficult movements. It's a pity that there is no movable part at the wrist. It would be even better if there was a single joint movable part.
In addition, there are other things that make DIY players happy: The PC of AELOS 1S shell is designed in consideration of the needs of the players. It is fixed by a snap. It can be disassembled and self colored to assemble a completely unique AELOS 1S. Customized services have always been discussed inside Leju. When the time is ripe, it will be considered to launch it to the market.
How to control
In terms of control, Leju has designed two apps for AELOS 1S, namely the AELOS 1S app for direct control and the AELOS STEM for personalized building block programming with Blockly. Let's take a look at the AELOS 1S app first. The AELOS 1S app interface is not complex, and three major segments are directly presented to users, namely, action market, remote control and DIY action.
Entering the main remote controller, you can see that the layout of the handle is very similar to that of the common handle. The overall operation logic is not difficult. The two remote sensors at the bottom are used for walking movement, and the double cross keys at the top are used to achieve the corresponding action mode. The stop button at the bottom left can immediately stop the action of AELOS 1S and restore to the original state.
Of course, as a scientific enlightenment robot, AELOS 1S naturally supports DIY actions, and users can edit and adjust relevant actions as special actions of AELOS 1S. It has to be said that this DIY action is still a bit difficult. AELOS 1S needs to keep balance and make actions at the same time. When adjusting the action, it needs to be fine tuned repeatedly. However, the sense of achievement after the successful realization of AELOS 1S is really full.
The action market, as its name implies, is naturally the place to download and upload actions. Users can download DIY actions provided by Leju officials or other users, and also upload their own DIY actions to the market, so that AELOS 1S can achieve more interesting and fun actions.
In addition to using app control, Leju also cooperates with Turing to provide voice control options. In addition to the ordinary voice question and answer, AELOS 1S also provides the function of voice command AELOS 1S movement. Some less complex actions, such as walking forward and backward, random dancing, can be completed through voice command, which is a special feature of AELOS 1S voice control.
Of course, as an excellent humanoid robot, Leju AELOS 1S can be controlled by an external handle, which is basically similar to AELOS or other humanoid robots in the market, so we will not introduce it here.
Among the two apps provided by Leju, AELOS 1S app can be said to realize basic control, so that users can immediately experience the fun of humanoid robots, then AELOS STEM can make AELOS 1S play a greater potential, while cultivating logical thinking and programming ideas, more in line with the positioning of scientific enlightenment robots. The main interface of AELOS STEM is also composed of three parts, namely Explorer, New Project and My Project. AELOS STEM uses a fully visual programming language Blockly block programming released by Google, which is very suitable for programming enlightenment.
Among them, the Explorer module is specially set for beginners who are not familiar with programming. It is used to explore with AELOS 1S in combination with the main story, unlock the level step by step, and learn the main logic and methods of Blockly block programming, so that users can quickly start in entertainment. Leju official said that at present, more than 20 levels have been set up for explorers, and will be updated later.
The biggest difference between AELOS STEM and other visual programming is that it adds a special control category, which enables the program to realize loop and branch jump. Compared with the previous visual programming, AELOS STEM can only realize the sequence structure, which can be interrupted and jump through different variables, so AELOS 1S has more room to play.
Actual performance
On the surface, AELOS 1S seems to be close to other competitive products in the market, that is, it is more active and the app is more playable. What else does Leju have? That is the steering gear that is completely self-developed. In the field of humanoid robots, the United States and Japan are ahead. The most important thing is their steering gear, which is also a threshold for the development of related fields in China. On AELOS 1S, Leju has adopted a self-developed steering gear. By using aviation grade plastic gears in the steering gear, it has achieved lightweight and long service life, which is also the competitiveness of Leju. Not only that, the gait algorithm of humanoid robot, Leju said, is also independently developed by its own algorithm department, which is more competitive. How about its actual performance?
In the actual measurement, it can be seen that the AELOS 1S steering gear has a high degree of cooperation with the gait algorithm, and the overall operation is smooth. In addition, AELOS 1S does lift its feet off the ground when walking, unlike some humanoid robots, which only use big feet to drag.
Not only forward, the center of gravity of AELOS 1S keeps good when it retreats, but also the speed can keep consistent with the forward state, and it is no problem to retreat rapidly.
However, some difficult hip-hop, bow and other movements are more than enough. When properly set, the whole movement is very smooth and similar to the human movement. More importantly, AELOS 1S is equipped with a self balancing function, which can automatically get up and restore the initial state without manual intervention when falling due to unstable center of gravity or user error.
By making full use of the linkage of multiple joints, AELOS 1S can basically simulate any human action, but the change of the center of gravity must be taken into account when programming or DIY actions, otherwise AELOS 1S will have a "street beating" situation. After experiencing AELOS 1S, because of its high mobility and programmable action potential, I finally understood why AELOS 1S was chosen as the official competitive machine in some robot competitions. It is precisely because AELOS 1S can burst out a variety of possibilities after combining users' imagination.
summary
After a complete experience, the advantage of Leju AELOS 1S is that the action is more anthropomorphic and the action is highly customized, which benefits from Leju's self-developed steering gear and gait algorithm, making it more flexible than its competitors in the market; The existence of AELOS STEM makes AELOS 1S suitable as a product for programming, improves the potential of AELOS 1S, and makes AELOS 1S more competitive.
Leju AELOS 1S, as a product targeted at the age group of 9~15, is suitable for cultivating children's logical ability, thinking ability and practical ability at this age. It is also attractive to some robot enthusiasts. Those who need it in this regard may want to buy it.
