L3Harris developing a twin arm for its T7 UGV

The L3Harris UGV dual arm would have substantial applications in the security and police areas.

L3Harris expects to have a prototype of a new dual arm for its T7 UGV ready to demonstrate late in 2024 or early in 2025 with security and police personnel among the eventual solution’s targeted customers.  

The weapon which will combine a large lifting arm with five degrees-of freedom (DoF) and a smaller more dexterous arm for more intricate work with seven DoF. The dual arm will also be adapted to the T4 platform.

For the T7, the connection will be at the wrist and it will be to the main chassis of the T4 with the dual arm system serving as the primary manipulator for both. The heavy arm on the dual system will have a reduced lift capacity compared to the existing heavy arm on the T7.

While the development is occurring partially within a US Army effort, both UGVs are in service with security or police personnel. Applications for these types of users are apparent, ranging from package lifting and opening, to operating door handles, while also being able to heavy lift.

L3Harris is pushing the development of the integration of the dual arm system which is also separately being developed under the US Army’s Enhanced Robotics Payload (ERP) programme. Work is underway to enable control of each arm separately with L3Harris’ haptic control system.

The British Army operates 122 T7s and has ordered 50 T4s and the US Air Force’s 96th Test Wing at Eglin Air Force Base also operates T7s while the potential applications for the dual arm in a post-war Ukraine is also apparent.
