【Xin Zhiyuan Guide】Boston Dynamics Robot Dog gets another new skill. Recently, a YouTube blogger, Michael Reeves, used his technical expertise to tune the robot dog Spot to “pee” like a real dog.
Some time ago, a woman in Florida, the United States, “walked her dog” on the beach aroused onlookers.
Because what she is holding with the “rope” in her hand is actually a Boston-powered robot dog!
Now, the robot dog Spot has also learned to “pee”, this is the real dog…
And this peeing dog was “trained” by a YouTube blogger, Michael Reeves, using his technical expertise and talented mind.
Next time you go to “walk the dog”, you must bring it, the scene is very windy! “Reminder: Be careful of getting tickets when you urinate anywhere”
Dancing, skipping rope, cleaning the house, watering flowers, going to Tesla and other factories to “move bricks”, and now Spot has learned to “pee” again.
It can be said that Spot Robot Dog got a new skill.
But the location where the outlet pipe is installed is too “evil-interesting.”
Robot Dog Spot: I am not a real person, but you are a real dog!
The robot dog Spot “urines” beer into the glass and currently has more than 7 million views on YouTube.
Let’s take a video and feel it as a whole~
The original idea of blogger Michael Reeves was to make Spot the robot dog a good helper who can help people pour beer.
In the video, Michael kindly invites a friend to drink beer, but friends who see this scene should feel crazy.
“Dried this cup” really needs to overcome a great psychological barrier!
Netizens are curious, “How does it taste?”
At present, the accuracy rate of the robot dog under the supervision of Michael in pouring beer into the glass is only 35%.
Although it has not yet reached the level of “precise delivery”, this idea has already aroused enthusiastic comments from netizens.
Let the robot dog “pee” into the cup, how did Michael manage it successfully?
Training for 6 months, named “Pissbot 9000”
Michael said, “Training Spot requires some smart programming, and it took 6 months to complete.”
First, an important device is needed, a camera that can recognize where the cup is.
Since BD’s high-quality cameras cost nearly $30,000, Michael decided to use an off-the-shelf home surveillance camera, a wireless receiver and AV adapter.
Michael programmed the robot dog to find the brightest pixels recorded by the camera to identify the white interior of the red cup.
To avoid the camera’s confusion between the white ground and the white interior of the cup, Michael used the inverse square law in physics to change the point of light and project light into the surrounding environment.
The inverse square law is defined as: in any physical law, the distribution or intensity of a certain physical quantity will decrease in inverse proportion to the square of the distance from the source.
The modification that Michael had to make was not simply putting a small bucket on Spot’s back and then reprogramming.
He also designed a nozzle gimbal to aim the cup more precisely.
This device uses a servomechanism and a solenoid driven by the Raspberry-Pi “vision system” to ensure that the robot does not miss the cup.
The results of it? 35% accuracy rate.
As demonstrated in the video, “urine” sometimes spills out and messes up the floor.
By the way, this trained robot dog is no longer called Spot, and Michael named it “Pissbot 9000”.
Open source SDK, do it yourself DIY
In June 2020, Boston Dynamics opened the Robot Dog Spot to the public for public sale for $75,000.
It can walk at 3 miles per hour, climb terrain, avoid obstacles, see 360-degree images, and perform some programmed tasks.
In addition, it can also map the environment, sense and avoid obstacles, climb stairs and open doors. It can perform dangerous tasks in a variety of uninhabitable environments, such as nuclear power plants, offshore oil fields and construction sites.
In order to cooperate with the sales of this robot dog product, Boston Dynamics also open sourced Spot’s Python scripting language SDK.
You can directly control Spot with Python. Boston has open sourced Spot’s SDK, which means that after you buy Spot, you can use your own DIY functions. It is not a dream to have your own dedicated robot dog.
Just in February, a spoof organization in the United States tied a Tipman 98 paintball gun to the body of the Boston Dynamics Internet celebrity robot dog Spot, and let it wander in the gallery.
Naturally, this incident aroused heated discussions among netizens.
Boston Dynamics publicly condemned the violent, harmful, and threatening behavior for this.
Michael Reeves’s own DIY robot dog allows us to see the unknown side of Spot.
It is definitely a master who can tune a robot dog so well!
