The ST Robotics R12 5-Axis Articulated Robot Arm is a complete self-contained five vertically articulated robot arm system designed as a cost-effective solution for bench top automation. It has a useful 500mm reach and a 500g payload. The hand terminates in a mounting plate to which can be mounted one of our low-cost grippers, vacuum pickups or your own device.
R12 is a low-cost entry to real industrial robotics, fast, accurate and reliable and easy to program yet capable of the most complex tasks. It is a breakthrough in benchtop robotics, light and fast, using high-efficiency digital motors driving through steel-reinforced polyurethane timing belts. Optional incremental optical encoders provide exceptional integrity as well as safety (see below).
R12 is a professional tool made to industrial standards, machined from solid alloy and finished with aesthetic acrylic covers. The system is supplied complete with controller, all cables, connectors, software, and comprehensive manuals, ready to unpack and use immediately.
The R12 package includes the K11 controller that is simple and reliable using a partnership of CPU and DSP micro-processors and compact micro-stepping drives. ROBOFORTH II embedded software gets you started easily yet permits the most complex motions, interfaces and peripherals to be programmed, assisted by ROBWIN project manager that brings everything together on one Windows screen.

Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
While the same return policy applies, these orders require a separate contact process for returns.
