Plan your first robot arm

Start on a table. Understand the parts before adding wheels.

Not physically tested by Modurobot. The SO-101 is a different robot from the tall, telescoping-arm villa model. This guide does not connect that physical arm to the villa AI.

BEFORE YOU START

The scope of this version

A purchasing and test worksheet for the documented SO-101 platform. The motor kit and printed parts subtotal is $279.80; the camera adds $12. This is not an all-in robot price.

01

Choose the exact kit

Check the supplier SKU and current package contents. The motor kit and printed structures are separate products. Match the printed revision to the motors and leader/follower design; an adapter may already be included.

02

Finish the budget

Use the official bill of materials to confirm the required power supplies, USB cables, fasteners, clamps and computer. Reuse suitable equipment only after checking its requirements. Keep unpriced essentials in the shortlist.

03

Follow the manufacturer build

Use the official LeRobot SO-101 assembly, motor configuration and calibration instructions. Record kit revision, motor IDs, firmware and calibration files. This page does not replace that procedure.

04

Start with supervised movement

Secure the bench and follow the manufacturer setup procedure. First verify each joint, gripper and the stop procedure under direct supervision. Record any binding, heat, resets or unexpected motion before attempting a task.

05

Test one simple transfer

Choose one lightweight object and a fixed pickup/drop position. Record its dimensions, mass and lighting. Perform 20 supervised attempts and record successful transfers, drops, failed grasps and interventions separately. Twenty attempts are an initial comparison, not a reliability certification.

06

Publish what happened

Keep the same setup when comparing changes. Submit attempts/successes and failure details below. Upgrade one component at a time, repeat the same test and keep the old results for comparison.
