Electric excavators require more than replacing a diesel engine with an electric motor. They demand a carefully engineered combination of drivetrain, motion control, energy management and software.
Dot Robot designs and integrates the mechatronic systems behind electric excavators. By combining hardware and software into one coherent architecture, we help OEMs and innovators build electric machines that perform reliably in real-world construction environments.
Electric excavators operate under highly dynamic conditions. Slewing, lifting, driving and hydraulic functions often occur simultaneously, resulting in short but intense power peaks. At the same time, available onboard energy is limited and must be managed carefully to maintain uptime and performance.
Simply combining off-the-shelf components rarely leads to a robust solution. Without tight integration between drivetrain, power electronics and control software, machines suffer from unpredictable behavior, inefficient energy use or reduced reliability.
Dot Robot approaches electric excavators as integrated systems, not as a collection of individual components. We design architectures in which electric drivetrains, motion control and energy management are developed together and validated as one.
By aligning hardware choices with control software and operating profiles, we ensure predictable performance under real working conditions. This reduces development risk and enables electric excavators that are suitable for daily operation; not only for demonstration or testing environments.
Electric drivetrains & motion systems
We design and integrate electric drivetrains tailored to excavator duty cycles, including traction, slewing and auxiliary motion systems.
Control software & system architecture
We develop control architectures that coordinate motion, torque and power distribution, ensuring smooth operation and operator confidence.
Energy management & charging integration
We implement energy management strategies that balance performance, efficiency and charging constraints, including integration with smart charging concepts where applicable.
Prototyping, testing & industrialization support
From early prototypes to validated systems ready for series production, we support development, testing and integration throughout the project lifecycle.
Electric excavator development takes different forms depending on the starting point. Dot Robot supports a wide range of projects, including:
Electrification of existing excavator platforms
Development of new, fully electric excavator concepts
Scaling prototypes into reliable, repeatable production systems
In each case, the focus remains on system performance, reliability and long-term scalability.
Relevant experience in electric heavy machinery
Dot Robot has experience in developing and integrating electric motion systems for heavy-duty and off-highway applications. This includes projects in industrial machinery where high loads, safety requirements and uptime are critical.
Our experience in these domains translates directly to the challenges faced in electric excavator development.
Whether you are exploring electrification or already developing an electric excavator platform, Dot Robot can support you with system-level engineering and integration.
