Trossen Robotics

Advanced

A US research robot-arm maker selling WidowX, ViperX, and complete ALOHA kits.

Trossen Robotics is a US robotics hardware company founded in 2004 by Matt Trossen, headquartered in Downers Grove, Illinois, and long focused on selling robot kits for research and education. It became well known in embodied-AI circles because its low-cost Interbotix arms are used in a huge number of academic projects: the BridgeData V2 dataset used a WidowX 250, and Stanford's ALOHA dual-arm teleoperation platform uses a ViperX 300 as the follower arm and a WidowX as the leader. The company now sells complete ALOHA hardware kits directly, in both stationary and mobile versions, including the leader and follower arms, multiple cameras, and data-collection software — letting a lab start collecting imitation-learning data within hours of unboxing.

ExampleMany labs reproducing ACT or Mobile ALOHA buy a complete ALOHA dual-arm kit straight from Trossen to collect their demonstration data.
