Robots in this library

Fourier GR-2

A human-sized robot for movement and arm research. It suits engineering teams; the retained documentation is older, so today's configuration and support need checking.

Purchase stage: Not established. The representative specification/support check does not establish current exact-package orderability, stock or completed deliveries.

Price, software and support notes

Price: No comparable current exact-configuration public purchase price verified in this pass.

Unknown; quotation, regional terms or exact configuration still needed.

Regional scope: Current regional purchase, warranty and repair coverage is not fully verified; do not assume a UK offer from a global product page.

Software: It sits on the maker’s older documentation domain; confirm that it matches the delivered firmware and hardware. The maximum-torque summary and individual joint table use different values, so do not apply one maximum to every joint.

Support: Fourier’s retained GR-2 documentation supplies joint limits, electrical ports and controller information. It sits on the maker’s older documentation domain; confirm that it matches the delivered firmware and hardware. The maximum-torque summary and individual joint table use different values, so do not apply one maximum to every joint. Warranty, repair shipping and available replacement modules remain quotation-specific.
