Overview

A family of six-axis YAM arms supported by a Python and CAN control library with revision-specific models. [S001]

The preserved I2RT release v1.3.6 is a Python control library, with models and examples for YAM hardware. Its six-axis variants map to these selectors: YAM (yam), YAM Pro (yam_pro), YAM Ultra (yam_ultra), YAM Ultra 2 (yam_ultra_2) and Big YAM (big_yam). Select through --arm or arm_type=; no_arm covers a gripper-only robot. Ultra 2 keeps Ultra's kinematics but changes link inertials and the joint-four motor; a shared shape is not enough to select the model. [S001] [S002]

Gripper selection is separate. The identifiers are crank_4310, linear_3507, linear_4310, flexible_4310, yam_teaching_handle and no_gripper; the last selects a bare terminal mount. Linear grippers require a closed starting position or calibration because motor travel exceeds one revolution. The documented host route uses Python 3.11, Linux dependencies and CAN at 1 Mbit/s. [S001]

Read the specification labels literally: arm mass excludes the gripper and tips, and chain length sums joint-origin translations rather than measuring reach. Neither should be copied into a complete-arm specification without its qualification. [S001]

The MIT license covers this software repository. A complete hardware manufacturing pack, its rights and a current configuration-specific price were not established here. No robot code was executed and no physical calibration or support workload was measured. [S003]
