Tesla Bot 2025 Update: What's New in Tesla's Humanoid Robot
Tesla is pushing the boundaries of robotics with the development of the third generation of their Optimus humanoid robot. Promised to be the most advanced humanoid robot in the world by Elon Musk, the Tesla Bot Gen 3 faces increasing competition as the robotics market heats up. With many robots emerging globally, it’s critical for the Tesla Bot to deliver on Musk's promises. Here’s a look at the groundbreaking features that keep Optimus ahead of the curve.
1. Advanced Hand Design
The human hand is one of the most complex body parts to replicate in robotics, but Tesla is making significant strides. The Tesla Bot Gen 3 will feature a new hand design with 22 degrees of freedom, a significant upgrade from the 11 degrees of freedom in the current Gen 2 model. This allows the robot to mimic the full range of human finger movements, including an additional knuckle joint that is crucial for a more natural grip.
Tesla’s progression in hand design reflects Elon Musk’s philosophy of “the best part is no part.” Early versions of the Tesla Bot hand were minimalistic, but as the robot evolved, so did the complexity of its hands. The Gen 3 hand will be capable of intricate tasks like playing the piano, demonstrating the robot’s improved dexterity.
2. Comparison with Competitors
Tesla’s main competitor in the humanoid robot market is the robotics company Figure. Their Figure 2 robot features hands with 16 degrees of freedom, including the third knuckle, allowing for a firm grip. However, Tesla’s Optimus has a more human-like anatomy, with sleek hands and fingers powered by metal tendons, similar to human muscles, which contrasts with Figure’s bulkier design.
3. Linear Actuators vs. Rotational Actuators
Another key distinction between Tesla and Figure’s robots lies in the choice of actuators. Tesla prefers linear actuators, which function like pistons to mimic human muscle movements, while Figure uses rotational actuators, which are more akin to traditional electric motors. This difference results in Tesla’s robot having a more fluid, human-like movement.
4. Factory Applications
Tesla’s robots have already been seen in action at their Fremont factory, performing tasks like handling 4680 battery cells. Though the robots move slowly, they can complete these tasks, and Elon Musk has hinted that more Bots will be deployed for factory work by the end of the year.
5. Voice and AI Integration
For a humanoid robot to be truly useful, it needs to communicate effectively. Tesla plans to equip the Gen 3 Bot with a voice and customizable personality, enabling it to interact more naturally with its owner. The voice functionality will likely be powered by X.ai’s Grok 2 language model, a strong competitor to OpenAI's GPT-4, which powers Figure’s robot.
While Figure’s robot already features voice interaction, Tesla aims to push the boundaries of what’s possible by integrating Grok 2 directly into Optimus. However, the challenge remains in balancing energy consumption between the robot’s physical capabilities and its AI processing power. Currently, the AI runs on a server, with the robot connecting via Wi-Fi, but future developments may allow for more energy-efficient onboard processing.
Conclusion
The Tesla Bot Gen 3 promises to bring revolutionary advancements in humanoid robotics, from improved hand functionality to advanced AI-driven communication. As competition intensifies, Tesla’s ability to innovate will determine its success in the rapidly growing field of robotics.
