- Saft Li-ion battery packs can power the Mirokaï robots developed by Enchanted Tools throughout an eight-hour shift
- Bespoke battery packs manufactured in Poitiers, France, are based on Saft’s latest lithium-ion technology
- Enchanted Tools expects to manufacture 100,000 of its humanoid robots over the next decade
Saft, a subsidiary of TotalEnergies, has signed a contract with Enchanted Tools to supply rechargeable battery packs for the new generation Mirokaï humanoid robots. The Mirokaï battery packs are based on Saft’s latest MP176065 xec lithium-ion (Li-ion) cells configured to power the robots throughout a long working shift.
A reliable battery is essential to the success of our Mirokaï robots. But we were faced with a real challenge: finding a solution that met our requirements in terms of autonomy and lifespan. It also had to fit in with the unique and original design of our robots.
“That’s when Saft came up with a relevant and effective solution. With the new Saft battery, we achieve autonomy of several hours with only very short recharge cycles, matching the needs of our users,” said Jérôme Monceaux, CEO of Enchanted Tools.
Enchanted Tools has created the Mirokaï concept to meet the booming demand for humanoid robots, especially in hospitals. The robots are designed to combine the useful and the wonderful, using multiple artificial intelligence features to interact with users, orient themselves autonomously and perform logistical tasks in contact with untrained users. Inspired by an original imaginary world, Mirokaï robots have a unique design and innovative technical features; an interactive face that reacts to situations in real time, two arms that can manipulate objects, and an innovative movement system based on a rolling globe.
“This is a very exciting development for Saft. We have a long track record in robotics, especially in providing batteries for automated guide vehicles (AGVs). But the Mirokaï project is the first time that we have given life to humanoid robots,” commented Cedric Duclos, CEO of Saft.
Saft is manufacturing the 25.55 V Mirokaï batteries at its factory in Poitiers, France. They are based on Saft’s latest MP176065 xec high-energy, fast-charging cells configured to deliver a capacity of 16.2 Ah and a nominal energy of 414 Wh. The battery packs are engineered specially to fit the battery housing on the back of the robot while providing a high level of thermal management to handle the heat generated during both charging and discharging cycles.
So far, Saft has delivered battery packs for 28 Mirokaï prototypes. However, production is expected to ramp up sharply from 2026 to support Enchanted Tools’ goal to deliver 100,000 humanoid robots over the next 10 years.
