...to Make Music Videos! lol. And at 16 cents/share post-market downturn, XBOTF Realbotix stock is looking pretty good too! Plus these lifelike companion robots are the $11k popular version of the $150k Aria robot animated from the ankles up and showcased at CES 2025. They are animated from the neck up and also the only lifelike companions that are made in the USA and insulated from the Trump Tariffs.

This is the same video but different perspective and higher quality. Clearly no CGI because the robot drops after its performance was finished and iShowSpeed comes in action. Probably part of the performance.

What are the current limitations in hardware and electronics when it comes to advancing robotics, particularly in areas such as processing power, energy efficiency, sensor integration, actuation, and materials?

So, besides little cars and stuff like that, I was never able to really make use of them until recently-ish that I got a 3D printer and learned CAD, so it was time to categorize them.

This is literally my second time posting. My problem with my line tracing robot was that one wheel moves the opposite. I tried doing what the other told me and it really messed up everything because if I make changes, the wheel that used to be the one that spins backwards now moves forward while the other that used to move forward now moves backwards. Tried doing some changes in the code, nothing still worked. This was the code I used:

define IR_SENSOR_RIGHT 11

define IR_SENSOR_LEFT 12

define MOTOR_SPEED 180

//Right motor int enableRightMotor=6; int rightMotorPin1=7; int rightMotorPin2=8;

//Left motor int enableLeftMotor=5; int leftMotorPin1=9; int leftMotorPin2=10;

void setup() { //The problem with TT gear motors is that, at very low pwm value it does not even rotate. //If we increase the PWM value then it rotates faster and our robot is not controlled in that speed and goes out of line. //For that we need to increase the frequency of analogWrite. //Below line is important to change the frequency of PWM signal on pin D5 and D6 //Because of this, motor runs in controlled manner (lower speed) at high PWM value. //This sets frequecny as 7812.5 hz. TCCR0B = TCCR0B & B11111000 | B00000010 ;

// put your setup code here, to run once: pinMode(enableRightMotor, OUTPUT); pinMode(rightMotorPin1, OUTPUT); pinMode(rightMotorPin2, OUTPUT);

pinMode(enableLeftMotor, OUTPUT); pinMode(leftMotorPin1, OUTPUT); pinMode(leftMotorPin2, OUTPUT);

pinMode(IR_SENSOR_RIGHT, INPUT); pinMode(IR_SENSOR_LEFT, INPUT); rotateMotor(0,0);
}

void loop() {

int rightIRSensorValue = digitalRead(IR_SENSOR_RIGHT); int leftIRSensorValue = digitalRead(IR_SENSOR_LEFT);

//If none of the sensors detects black line, then go straight if (rightIRSensorValue == LOW && leftIRSensorValue == LOW) { rotateMotor(MOTOR_SPEED, MOTOR_SPEED); } //If right sensor detects black line, then turn right else if (rightIRSensorValue == HIGH && leftIRSensorValue == LOW ) { rotateMotor(-MOTOR_SPEED, MOTOR_SPEED); } //If left sensor detects black line, then turn left
else if (rightIRSensorValue == LOW && leftIRSensorValue == HIGH ) { rotateMotor(MOTOR_SPEED, -MOTOR_SPEED); } //If both the sensors detect black line, then stop else { rotateMotor(0, 0); } }

void rotateMotor(int rightMotorSpeed, int leftMotorSpeed) {

if (rightMotorSpeed < 0) { digitalWrite(rightMotorPin1,LOW); digitalWrite(rightMotorPin2,HIGH);
} else if (rightMotorSpeed > 0) { digitalWrite(rightMotorPin1,HIGH); digitalWrite(rightMotorPin2,LOW);
} else { digitalWrite(rightMotorPin1,LOW); digitalWrite(rightMotorPin2,LOW);
}

if (leftMotorSpeed < 0) { digitalWrite(leftMotorPin1,LOW); digitalWrite(leftMotorPin2,HIGH);
} else if (leftMotorSpeed > 0) { digitalWrite(leftMotorPin1,HIGH); digitalWrite(leftMotorPin2,LOW);
} else { digitalWrite(leftMotorPin1,LOW); digitalWrite(leftMotorPin2,LOW);
} analogWrite(enableRightMotor, abs(rightMotorSpeed)); analogWrite(enableLeftMotor, abs(leftMotorSpeed));
}

PLS PLS PLS HELP ME 🙏 I am so desperate to fix my robot rn. The photo below shows the diagram I followed.

Hey I am a 15 year old who knows nothing about robotics, how long do yall think it would take me to learn robotics and how should I get started

Hello fellow robotics enthusiasts, I am in a deep dilemma of whether changing my carrer to be a ai/ml expert and been feeling low and confused if I truly have to let go of my robotics.

So a short intro, I come from a urban City chennai in the asia,worked so hard all through my highschool and scored 99.7%,just so that I can get into a scholarship and now in my second year of robotics and automation paying around 450$ a year as tuition.(My brother's tuition is around 15 times more than mine and yes my family could have afforded to pay for me but I chose to save money)both my brother and myself are going to do masters in a foriegn country and plan to migrate.both my brother and myself will be taking loans and the loans in total would be around ten years of earnings of my parents

Having worked hard through my life till date to upbring my family and live a very relaxed life ,I chose to work really hard in my college and did plently of robotics projects including working with Indian space reasearch for building a mars drone,yet feeling confused.

I have worked as much I could afford with ai/ml and cv ,just so that I felt that can help me with robotics. The confusion only arised from the pay and the job security I am assured in this field ,I WISH TO PURSUE ROBOTICS yet the aluminis,seniors,the internet all says that a robotics job is not paying enough compared to a ai/ml engineer and I really don't want to risk any part of my plan to settle in Europe France

Will myself pursuing robotics be rewarding my future? Please I want all kinds of answers from anyone and everyone who can spend a little bit of time to give an advice to a budding engineer in my life

I built a humanoid robotic arm for my latest YouTube video but nothing went according to plan. I went through my whole design process, assembly and more demos. Luckily I was able to get some nice shots of the arm in action before it broke. Here I’m using these super nice harmonic actuators and 3D printed all the parts. Stay tuned for next gen and integration with ROS!

Ive seen many fast line followers like the Cartis04, and I want to build one but i dont know where to start. I dont know the components that i should choose, like the motors, SPM32, and other such components. I want the robot to be fast so its able to compete. Thanks in advance!

Hello Robotics Community!

I've been trying to approach the <3cm/km translational accuracy for a long time now. Even the latest generation MEMS IMUs like the ADIS16507-2 in Conjunction with barometer and Magnetometer cannot approach that figure.

Not even VSLAM can approach this, only LIDAR slam that costs thousands.

RTK base stations do not work from hundreds of KM away. But, what if I can have the drone land and drop a RTK module at a visually recognizable setpoint from aerial imaging, and use that as a RTK station? Would this work? Thanks.

Hello,

Does anyone have any experience with modeling a robot arm in UE5? I am setting up a photorealistic simulation, and for this purpose I would like to use any robot arm model and be able to pass in joint angles to make the robot move (with physics enabled).

So far, I have seen there are two approaches:

1. Skeletal Meshes: This seems to be the way the gamedev people usually set up a robot. I do not know much about this, but it seems alright for creating animations, don't know if I can get realistic movement (and most importantly, control in the joint space) out of this method.

2. Serial chain of Links bound by Physics Constraints: As someone coming from a robotics with ROS background, I'm keen on this approach because I can use the URDF to set up the links and then the joints are Physics constraints. I even tried using this approach, but I don't get a realistic simulation from it.

I have no experience with UE5, as such I'm struggling with setting the robot up. Looking forward to hearing from people who use UE5 to build simulations. Any help will be appreciated, thanks!

Anyone have the pdf of this paper: A Multimodal Robotic Blackjack Dealer: Design, Implementation, and Reliability Analysis ? Any 'pdf' link just brings me to this website, which blocks it with a paywall: https://link.springer.com/chapter/10.1007/978-3-031-44981-9_24 . Looking for anyone who may have bought this already and is willing to share ! thanks
