As the energy transition calls for increasingly complex field operations, DSOs strive to enhance risk management, improve ergonomics and open work opportunities to a more diverse set of employee profiles. In 2018, Enedis launched a project to automate medium voltage works, which included a proof of concept of remotely operated robotic arms for the manipulation of tools on overhead lines. The resulting prototype, called TST-Bot, was designed to support several use cases while reducing physical effort and improving the safety of technicians.
The TST-Bot is built on a spider lift platform equipped with two robotic arms and is designed to allow operation under a wide range of weather conditions. The robotic components of the TST-Bot passed several tests conducted to ensure their reliable performance when in contact with energised components. Throughout 2025, the TST-Bot will be tested by four Enedis live working teams as the first step towards the potential industrialisation and rollout of the solution across the entire Enedis service area.
