Bolucap

Within the BOLUCAP project, we aimed to develop an ingestible sensor for the rumen, a sensor which captures the body temperature, overall activity, and rumen contractions of the goat. The rumen is the largest pouch of the stomach of ruminants like goats and cows.

Once in place, the sensor will collect data and transmit them to a gateway on the farm, where they will be translated into actionable advice for the farmer and insights into the health of the herd.

The outcomes

Within the BOLUCAP project, we were able to conceptually show the complete end-to-end chain, from harvesting raw data through a bolus to visualising the data on an online dashboard. The three main outcomes of the project are:

• A functioning rumen bolus containing sensors for monitoring temperature and movement. These sensor is able to withstand the acidic environment of the rumen and does not hinder the animal.
• A cloud-based web application to store, process, and visualize sensor data coming from a gateway installed in the barn. The online dashboard allows the farmer to inspect information on individual goats and on groups of goats.
• A Machine Learning algorithm that takes in the raw data obtained by the bolus, and outputs a diagnosis of the goats’ health, in the process also identifying outliers. To arrive at this result, we also used an embedded ML model derived, step-by-step algorithm on the bolus to balance the bolus’ energy consumption between wireless transmission and AI calculation.
