Possibly ≤ 1 weekShipping: 8–13 business days. Rotrics' policy says orders ship within three business days and take 5–10 business days to the US, with $45 shipping on orders under $1,000 (October 2026). RobotShop lists the Starter Kit as on demand. Rotrics store ↗

Remote control: Connects over USB serial. The official pydexarm Python module wraps Marlin G-code so a laptop script can move it directly.

Overview

Launched on Kickstarter in January 2019 as the 'Hexbot', it raised over $840K from 1,600+ backers and was rebranded DexArm that November. The company says all backer orders shipped by October 2020. It is a modular multi-tool desktop arm (laser engraver, 3D printer, plotter, gripper) rather than a manipulation research arm. The store still lists it, but public development has slowed, with the last push to Rotrics' Marlin firmware repository in December 2024.
