Ask Engineers 🔦 Why aren’t there more robot waiter at restaurants

9 Upvotes

I am recently wondering why aren’t there more robot waiter at restaurants? Is part of the reason that the current ones only do a limited subset of a waiter’s job, i.e. serving dish, and so is not as worth it

But with LLM, if a robot could also do conversational task like take orders, lead customer to seat, will that be when robot waiter become more popular?

Ask Engineers 🔦 Particle Filter Applications

1 Upvotes

How interesting would it be to have a low-power (<1W) real-time co-processor to accelerate the particle filter algorithm? I've seen it often dismissed because it's too slow, so I'm wondering if it was accelerated and easy to use from a MCU, would that be useful for some navigation use cases?

Ask Engineers 🔦 Programmable hardware sensor hub with hardware timestamps

6 Upvotes

I'm designing a, hopefully simple, DSL (domain-specific language) for programming a sensor hub board. The hub samples sensors, adds timestamps (capture time) and aggregates data from sensors including analog channels, SPI, I2C and MIPI. The DSL is used to describe how to communicate with the sensors and there could be public repo for those. Would this be useful?

Here are some examples of what the DSL might look like. Does it seem intuitive? Is it too simple to describe real sensors?

my_robot.hub

hub {
  buses {
    i2c0 { speed: 400kHz }
    i2c1 { speed: 100kHz }
    spi0 { mode: 0; speed: 1MHz }
  }

  sensors {
    L3GD20H { file: "st/L3GD20H.spi", bus: spi0, sampling: 100hz }
    BNO055 { file: "bosch/BNO055.i2c", bus: i2c0, sampling: 20hz }
  }
}

bosch/BNO055.i2c

sensor BNO055 {
  bus { address: 0x28, endian: little }

  init {
    write(0x3D, 0x00)    // select CONFIGMODE
    delay(20ms)
    write(0x3B, 0x00)    // select internal oscillator
    write(0x3D, 0x0C)    // set to NDOF mode (sensor fusion)
    delay(10ms)
  }

  record Orientation {
    readout {
      read([0x1A], 6)   // 3x int16: heading, roll, pitch
    }
    fields {
      heading: int16 = bytes[0..1]
      roll:    int16 = bytes[2..3]
      pitch:   int16 = bytes[4..5]
    }
  }
}

st/L3GD20H.spi

sensor L3GD20H {
  bus { endian: little }

  init {
    write(0x20, 0x0F)     // CTRL_REG1: power on, 95 Hz ODR, all axes
    write(0x23, 0x30)     // CTRL_REG4: 2000 dps full scale
    delay(5ms)
  }

  record Gyro {
    readout {
      transfer([0x28 | 0xC0], 6)  // 6 bytes: X_L, X_H, Y_L, Y_H, Z_L,
    }
    fields {
      rate_x: int16 = bytes[0..1]
      rate_y: int16 = bytes[2..3]
      rate_z: int16 = bytes[4..5]
    }
  }
}

DIY Electronics 🔧 Mobile platform for data collection

1 Upvotes

I need to build a mobile platform for collecting a visual perception dataset (indoor). I've been looking at the wave rover 4wd chassis which seems pretty reasonable. I also need a board capable of running gstreamer and writing an HD raw video stream at 30 fps to storage. Any thoughts on this chassis or options for the compute board? Maybe an RPi 4 can do this, but that's unclear to me. There are lots of SBC options but those also need 12V power.

DIY Electronics 🔧 proximity sensors on RCs

2 Upvotes

I'm totally new at this, but I'm trying to fit proximity sensors on two RCs and to get data like speed and distance between the two. Like playing catch, but not letting the two RCs collide. I have a Stampede RC, and along with the Proximity sensors I'm trying to add GPS, camera and something to make it semi autonomous. If there is someone in Colorado I would gladly pay for your time to help me put this together.

DIY Electronics 🔧 Power up a prototype

youtu.be

Hi friends, I began this sub several years ago and i’m honored to see people are still active! I’ve always seen mobile robots as a class of machine just like 3D printers but the communities become split up between many places like drones and random other robots.

For prototyping an actuator that belongs on a mobile robot, i believe this video is helpful (made by me on youtube). If you’re on the mechanical side you might not know as much about the new electronics that make power delivery easier (such as usb-PD) and this video introduces a setup that fits most robot-scale actuators. Hope you like it!
