Embraer Phenom 300 Hydraulic Power Unit – Robomule
Editor's Note – The Robomule has been discontinued and is no longer available for purchase. Its successor – the Alberth Aviation MM-3200 Mobile Mule – offers expanded aircraft compatibility, improved portability, and the same core capability of supplying hydraulic power for operational checks without the need for a traditional hydraulic power cart. PJi is proud to carry the Mobile Mule and support its use across a wide range of business jet and general aviation aircraft.

Key Takeaways
- Embraer validated the Robomule as an approved alternative hydraulic ground power source for the Phenom 300, suitable for performing hydraulic checks such as landing gear cycle checks.
- Rather than replacing the aircraft's hydraulic system, the Robomule drives the aircraft's engine-driven hydraulic pump (EDP) via a motorized accessory drive, using the aircraft's original pump, filters, pressure regulator, and fluid already installed on board.
- The Robomule connects directly to the Phenom 300's EDP without requiring an adapter or spline change, and is operated by a standard 28V DC external ground power unit.
- Because it works within the aircraft's existing hydraulic system, the Robomule eliminates the risk of contamination, air ingestion, over-pressurization, and fluid loss – common concerns with external hydraulic power carts.
The Robomule was recently featured in the Embraer Executive Jets Newsletter as an alternative hydraulic ground power source. Please review the full article below from Embraer...
Embraer validated the Robomule as a Phenom 300 alternative ground power source. The Robomule is used as a power source for performing several hydraulic checks, such as landing gear cycle checks. The Robomule is connected to the engine drive hydraulic pump (EDP) for the Phenom 300 without requiring an adapter or spline change, and is designed to work well across all aspects of the maintenance event.
The Robomule utilizes the aircraft’s original equipment, engine-driven hydraulic pump, filters, pressure regulator, and fluid installed on the aircraft by providing a motorized accessory drive to the aircraft hydraulic pump (EDP), rather than the aircraft’s turbine engine, as shown below. The unit is operated by a 28V DC external aircraft ground power unit.
The Robomule’s adaptation substitutes an external hydraulic power cart, prevents contamination of the hydraulic system, eliminates the risk of air entering the hydraulic system, and prevents overpressurization of the aircraft’s hydraulic system. Also, the Robomule does not allow or provide a method for fluid loss or leaks, and is quick and easy to install and utilize.
The Robomule requires aviation experience and aviation technical skill to adapt to the aircraft and use it safely, properly, and efficiently. Further information for the operational check using the Robomule is available on Flyembraer AMM 29-10-00-710-803-A, as well as its characteristics in the Item (3716) – 030 – Non Tool Sheets – List of Standard Tools.
