- Tesla proprietor Pat Larson has invented his have automatic charger.
- A Raspberry Pi computer system serves as the brains of the operation.
- The charger takes advantage of a digital camera and a sensible light bulb to place its long arm that connects to the car’s charging port.
Earlier this month, YouTuber Pat Larson flaunted his “Tesla Automated Charger” in a new movie. The robotic charger can automatically join to the car’s charging port with an arm-like apparatus that works by using a digicam, a Raspberry Pi laptop or computer, and a bit of equipment understanding.
It truly is the kind of charging technology that Tesla CEO Elon Musk has teased just before, but has not still delivered. So let us just take a appear at Larson’s charging setup to see what is heading on below the hood.

The Raspberry Pi is “the brains of every thing,” Larson states in the YouTube video. To start out, the program moves back again and forth on linear bearings, aligning approximately with the charging port space of the motor vehicle. A linear actuator (mainly, a joint) pivots the charging arm mechanism absent from the wall and toward the parked Tesla.
An automatic servo motor “rotates the charging deal with out when it truly is necessary,” Larson describes. Then, an ultrasonic distance sensor presents suggestions to the computer so that the charging arm won’t strike the car or truck.
Lastly, a little camera snaps photos and feeds them again to the computer system method to aid line up the charging arm system. The Raspberry Pi is geared up with a machine learning framework named TensorFlow, which aids the technique realize in which to go based on the photographic proof. There is also a mild to illuminate the proper place, just in scenario it is dark inside of the garage.
In the video clip, Larson presses a button to boot up the process, then watches as the “reasonably complicated TensorFlow product” kicks into equipment gradually. “It is not a quickly process,” he states. The arm navigates away from the wall, even though the brilliant light centers on the spot exactly where the arm need to go. Then, the software package opens the charging port utilizing the Tesla API.
Upcoming, the actuator swings out the significant portion of the arm with the charger suggestion. Ultimately, the pivoting charger head entirely aligns alone flush with the charger port. The charger head spots the hole by pinpointing the dazzling Tesla “T” that generally exhibits when the charging port is open up. The charger traces by itself up properly and pushes into the slot, activating the charging port.
Larson explains that all of the software program operates in excess of the online, which technically means the system could go out if there have been an online outage—a “weak point in the program,” he admits. But of class, in that circumstance, he can just plug the charger in himself.

Computerized chargers have lengthy been a Tesla chatting stage. In the previous, Musk has even talked about the plan of an official Tesla-branded automated charger. But that was in 2015, with no news considering the fact that. Musk did, even so, validate last 12 months that the “metallic gear snake” automatic charger is continue to on Tesla’s development road map.
For now, prepare to plug in your charger yourself.
