Our Soluton


“Geothermal energy” refers to the energy stored as heat below the earth's surface and a significant amount of heat of around 30° C is available at depths of 250 metres. This geothermal energy can be extracted using drilling.

Conventional Drilling Method

Our Solution


Issues with the current techniques to access geothermal energy include:

  • large space requirement for the geothermal probe (minimum need of 50 sq.m.) and location restriction as a distance of approximately 10 m must be maintained from the adjacent borehole or underground construction traffic systems

  • high costs due to the reconstruction of the destroyed landscape

  • high energy leading to a larger carbon footprint

  • environmental hazards such as earthquakes due to high hammering impact on the earth

  • delayed detection of water table penetration and noise pollution of about 120 dBA

  • high acquisition costs (approx. CHF1.5 million) and personnel costs lead to a high price of currently CHF 16'000 per 250 m borehole or CHF18'000 incl. geothermal probe.

About 3.2 million geothermal heat pumps will be installed in Switzerland and Germany by 2035. Our robot can do away with all the conventional disadvantages mentioned above.

Borobotics introduces 'Grabowski' - our first drilling robot that is based on the well known story character created by Luis Murschetz in 1972. Grabowski is also known as 'Mister Mole'.

Our solution in contrast to the conventional method is:

  • cost-effective and space-saving construction implies that more households can benefit from geothermal energy, and this transition can be accelerated

  • quiet and compact

  • energy efficient

  • low cost of drilling the borehole as the drill itself has low manufacturing costs and an autonomous mode of operation in manufacturing costs

  • clean and environmental friendly as the bore robot consumes only 127 kg CO2 per drilling; implying a saving of 14.4 million tons of CO2 on all geothermal probes until 2035
