AI Summary

LeSlider extends the SO-101 robotic arm with a linear slider motor to create a 7-degree-of-freedom system for teleoperation and dataset recording using the LeRobot framework.

How It Works

1
🔍 Discover LeSlider

You see a cool demo of a robot arm sliding back and forth on a rail, perfect for making your robot reach farther.

2
🛒 Gather your parts

Buy a few extra pieces like a rail, wheels, bolts, and a motor to add to your existing robot arm kit.

3
🖨️ Print custom pieces

Use your 3D printer to make legs, a base mount, pinion gear, and track segments that fit perfectly.

4
🔧 Assemble the slider rig

Bolt everything together, attach your robot arm to the sliding base, and connect the new motor to the chain.

5
💻 Set up on your computer

Follow simple instructions to prepare your computer so it can talk to both arms and the slider.

6
⚙️ Calibrate your arms

Guide each arm to its middle position and test its full range so movements feel smooth and accurate.

7
🎮 Take control

Use one arm as leader to mirror the other, and arrow keys to slide it forward and back – watch it come alive!

📹 Record your demos

Capture videos and movements of your sliding robot arm to train smart AI behaviors.

What is leslider?

Leslider is a simple slider add-on that mounts an SO-101 robot arm on a linear rail, turning it into a 7-DOF manipulator with keyboard-controlled base travel. Built in Python as LeRobot plugins, it handles teleoperation where a leader arm mirrors the follower (including base rotation), records datasets with slider actions/observations, and visualizes camera streams in Rerun. Users print parts, assemble with cheap V-slot extrusions and an extra servo, then run uv sync for CLI tools like lerobot-teleoperate and lerobot-record.

Why is it gaining traction?

It stands out with turnkey hardware BOMs, 3D-printable CAD on Onshape, and pre-made YAML configs for calibration, full-rig teleop, and recording—no custom scripting needed. Developers grab it for the seamless LeRobot workflow extension, adding linear reach to tasks like sliding and grabbing without rewriting robot interfaces. At 47 stars, it's a simple GitHub repo hooking robotics hobbyists tired of fixed-base limitations.

Who should use this?

LeRobot users with SO-101 arms experimenting with extended-reach manipulation. Robotics students building simple GitHub projects for datasets or demos. Researchers needing a cheap 7th axis for teleop and policy training on sliding tasks.

Verdict

Solid pick for SO-101 owners—excellent docs and assembly guide make it dead simple despite 47 stars and 1.0% credibility score signaling early maturity. Fork the configs, print and wire up; skip if you're not in LeRobot ecosystem.
