在近日的Munro Live采访中,特斯拉工程副总裁Lars Moravy与Eric Earley透露,特斯拉Optimus人形机器人正在学习给无人出租车充电,短期内预计将负责为Robotaxi车队插枪补能。
两人在采访中分享了不少Optimus与Cybercab的细节,据其介绍,Optimus的电池是一个约2.5kWh的独立模块,与汽车不同,电池包占整车成本四分之一到三分之一,电池并不是机器人的主要成本。
而充电只是Optimus的第一份工作,Moravy表示,它“可能会为车辆提供维护服务,也可能会切入配送领域”。
他同时描绘了一幅更大的图景,“你想想Cybercab、Optimus和Robovan,这三者的铁三角组合将会非常不可思议,此外还可以加上用于长途运输的Tesla Semi”。
此外,关于Cybercab的生产线信息同样首次大规模曝光,该车的总装线大约只有25个全自动工位,数量仅为Model Y生产线的五分之一到十分之一,自动化程度接近80%。
“开箱工艺”使每辆车的生产占地面积减少约50%,整车设计寿命50万英里。由于不设涂装车间(CyberCab不喷涂车漆),特斯拉省下了几亿美元。
有意思的是,目前产线的生产速度已经超过了Robotaxi车队的推广速度,所以产线并不是每天都在运转。
而Cybercab的4680电芯被封装在独立的灌封模块中,单个模块故障只需单独更换,无需更换整个电池包,电池包还首次采用钢制外壳,并为日后换装更便宜的磷酸铁锂电芯预留了空间。Moravy解释,“我们发现,实际需要的电池数量比原先预计的少”。
驱动形式上,Cybercab采用前轮驱动,传动比11:1,因为它不需要很高的极速。其全新逆变器也将在今年应用到Model 3和Model Y上。

In a recent interview with Munro Live, Lars Moravy and Eric Earley, Vice-President of Tesla Engineering, revealed that Tesla Optimus human robots were learning to charge unmanned taxis and were expected to be responsible for refilling the Robotaxi convoy in the short term.
In their interviews, the two people shared a number of details of Optimus and Cybercab, according to which Optimus' batteries were an independent module of approximately 2.5 kWh, which, unlike cars, accounted for between one quarter and one third of the cost of the vehicle as a whole and were not the main cost of robots.
The charge is only the first job for Optimus, which Moravy states that it “may provide maintenance services for the vehicle and may enter the distribution area”.
At the same time, he drew a larger picture, “Think about Cybercab, Optimus and Robovan, which would be an incredible triangulation, plus Tesla Semi for long transport”.
In addition, information on Cybercab ' s production line was also first exposed on a large scale, with only about 25 fully automated positions, one fifth to one tenth of the Model Y production line, and close to 80 per cent automation.
The “boxing process” reduced production by about 50 per cent per vehicle and the total design life of the vehicle was 500,000 miles. Tesla saved several hundred million dollars due to the absence of a paint workshop (CyberCab does not paint the car).
Interestingly, the production of the production line is now faster than the roll-out of the Robotaxi fleet, so the production line is not operating on a daily basis.
The Cybercab ' s 4680 electric cores, on the other hand, are contained in a stand-alone encapsulation module, with single module failure being replaced by a single unit, without the need to replace the entire battery bag, which also uses steel casings for the first time, and provides space for later replacement of cheaper lithium phosphate cores. Moravy explains that “we found that there were fewer batteries actually needed than originally anticipated”.
Cybercab uses a pre-wheel drive to move 11:1 because it does not need to be very fast. The new reversers will also be applied to Model 3 and Model Y this year.
