The use of autonomous robots in agriculture has been increasing rapidly in recent
years, but is hampered by the complexity of data recording and processing. The prototyping
process involves many changes to the housing design during development. Using laser cutting to
make a housing is more convenient, faster and cheaper than milling or casting if only one body
needs to be made. To speed up the production of autonomous robot prototypes, the body was
made of birch plywood using laser-cut parts. The study analyses the efficiency of passive cooling
to make sure that birch wood plywood is suitable for the production of a robotic body for outdoor
use in agriculture. Under laboratory conditions, temperature measurements were made inside and
outside the housing to determine how the heat released by the electronic components dissipates
into the environment. An exponential model with a static coefficient and a time constant can be
used to determine the recommended operating time at different ambient temperatures when the
allowable operating temperature of the component is known. Air flow and heat transfer
simulations were performed to represent heat dissipation. Birch plywood can be used for the
production of prototype enclosures for agricultural robots, but the design must provide
technological solutions for heat dissipation to prevent overheating of electronic components.
