The initially proposed tasks were:
• Validation of the system to measure the stability of the rifle during shooting.
(task T4A)
• Relate shot stability with effort control parameters (task T4B).


Biathlon carabina


Because the IMU was attached externally to the carbine and could
bothering the athlete at the time of manipulation, it has been preferred to postpone these tasks until a sensorized carbine was available. For this, it was necessary to carry out a 3D design for the housing of the electronics and readapt the electronics so that it would be embedded inside the housing made in the wood as shown in the previous one. These Homeworks
additional, caused a delay in the validation tasks. In addition, during the assembly of the
barrel, due to a misunderstanding, the electronics were removed from the wood, which caused a
additional delay of two months. Due to this, it has not been possible to carry out the planned biathlon trials, but they may be carried out in future trials.
