Intro#

🚀 Bringing Embodied AI to Everyone - Cheaper Than an iPhone! 📱

💵 ~$660 cost and ⏰ <4hrs total assembly time!!

Built upon the giants: LeRobot, SO-100/SO-101, Lekiwi, Bambot


News#

Hardware: The hardware setup for XLeRobot 0.2.0 is officially out! This is the 1st official hardware version that is fully capable for autonomous household tasks, with <1000$ cost.

Simulation: XLeRobot 0.1.5 is officially out! The current version includes a short technical blog and a detailed Step-by-step Installation Instruction, along with all the urdf files, control scripts that can get you started in 10 min.


🌟 Why XLeRobot? 🌟#

Let’s break this down since XLeRobot = XL + LeRobot

Why “LeRobot” Core?#

  • Cheap Materials 💴: 90% 3D printed components with affordable motors and electronics.

  • Easy Assembly 🔨: 67 minutes to assemble 2 SO101 arms and configure motors.

  • Plug-&-Play 🧩: Get robots running with simple pip install and a few lines of code.

  • Thriving LeRobot Community 🌍: World’s largest low-cost robotics community featuring

Why “XL” Enhancement?#

  • 🏠 The field/market lacks affordable, stable, dual-arm home robots that match LeRobot’s ease of assembly.

  • 🖨️ Traditional 3D printed chassis suffer from limited durability, stability, and load capacity—making them impractical for daily use.

  • ⚡ DIY mobile robots face power supply challenges, leading to complex wiring setups.

  • 🤖 XLeRobot maintains compatibility with the LeRobot community’s tabletop dual-arm SO-100/SO-101 configuration, enabling seamless code and policy transfer.

Description

Overall Advantages/Goals of XLeRobot#

  • Cost-effective 💴: Complete build costs $660, or upgrade from existing SO100Arm and Lekiwi for $250.

  • Easy upgrade ⏫ (physical and electrical) for Lekiwi and SO-100/SO-101

    • Hardware: No motor ID changes or hardware modifications needed

    • Software: Identical tabletop single-arm/dual-arm setup—transfer your trained policies directly from SO-100/SO-101 arm

  • Practical and reliable 💪: Performs many daily tasks comparable to $20,000 market alternatives.

    • More tasks demonstrated in the LeRobot hackathon in Shenzhen, Shanghai and San Jose(Winners), and the first one.

    • Note: Not currently designed for in-hand dexterity 🤹, heavy lifting (over 1kg per arm) 🏋️, or highly dynamic movements 🏃

  • Rich open-source resources 📕

    • LeRobot’s plug-and-play code🧩 and extensive AI model library🧠

    • Backed by an active, growing community of contributors🧑‍🤝‍🧑

  • ⚠️Safety always matters⚠️: XLeRobot has inherent physical hardware limitations (low-torque motors, short arm length, wheel-based) that make it physically almost incapable of harming humans, while still maintaining its ability to perform many household tasks.

    • Low-torque motors🦾: Even in the case of accidental contact, the robot is highly unlikely to cause injury. Additionally, its torque limitations prevent it from performing high-speed, dynamic movements.

    • Short arm length🦵: In the unlikely event that it’s holding a sharp object, the robot can be quickly disabled by tipping over the IKEA cart.

    • Wheel-based🧑‍🦼‍➡️: It cannot climb over obstacles higher than 10cm, so you can easily restrict its movement using blocks or stairs in case of unauthorized access attempts.

These👆 are staged photos, but they demonstrate what the XLeRobot platform can achieve within its hardware limitations. (The scenes are a bit messy, but hey, that’s life!)


🎯 Who is XLeRobot For?#

  • 🚀 Startups & Labs: Build prototypes faster with the world’s cheapest modular platform

  • 👩🔬 Self Researchers: Experiment with embodied AI without breaking the bank 💸

  • 🎓 Education Heroes:

    • High School Teachers: Bring cutting-edge robotics to STEM classes 🧪

    • University Professors: Affordable platform for robotics/AI courses 📚

    • Students: From beginners to researchers 🎒→🎓

  • 🤖 DIY Enthusiasts: Perfect for indoor projects - plant care, delivery bots, home automation 🌱📦


Limitations#

(Hey, for this price, what more could you ask for?)

  • 🔒 Fixed height—adding a stable lifting platform would significantly increase costs and assembly difficulty

  • 📏 Smaller workspace compared to Aloha—while we maximize the SO100 workspace, the arm has size limitations, though XLeRobot still handles most tasks effectively

  • ⚖️ Limited payload capacity for a single arm—that’s why we use the IKEA cart

  • 🛒 Base movement precision may be affected by the IKEA cart wheels—this can be addressed through closed-loop feedback control

All things considered—cost, community support, ease of assembly, and practical utility—XLeRobot stands out as one of the most compelling low-cost robot for indoor application!
