Break away mocap tracker

A motion capture tracking device comprising:

• a base portion, a detachable end cap coupled to the base portion and a plurality of motion capture markers coupled to the end cap;
• the base portion comprising:
• (i) an alignment body having first and second opposing surfaces and a sidewall extending fully around an outer perimeter of the alignment body between the first and second opposing surfaces;
• (ii) one or more base portion magnetic elements coupled to the alignment body;
• and (iii) a collar coupled to and extending away from second surface of the alignment body, wherein the collar includes a generally circular channel extending longitudinally through the collar and a clamping mechanism operable to tighten the collar to mechanically secure the base portion to a rod;
• and
• the detachable end cap comprising:
• (i) a front plate;
• (ii) a sidewall extending away from the front plate towards the base portion and defining an end cap recess having an inner perimeter such that the alignment body of the base portion can be fitted within the recess and mated with the detachable cap;
• and (iii) one or more end cap magnetic elements coupled to the detachable end cap and operable to cooperate with the one or more base portion magnetic elements to magnetically secure the end cap to the base portion when the end cap recess is fitted over the alignment body.

A motion capture tracking device comprising:

• a base portion having
• an alignment body having an exterior perimeter sidewall surface that defines a polarized mounting surface;
• one or more first magnetic elements coupled to the alignment body;
• and
• a collar coupled to and extending away from the alignment body, the collar having a generally circular channel extending longitudinally through the collar towards the alignment body and including at least one fastener hole extending into the collar at an angle perpendicular to the generally circular channel and a fastener operable to tighten the collar around an object inserted into the generally circular channel to secure the base portion to the object;
• an end cap magnetically attachable to the base portion, the end cap having
• a front plate;
• a sidewall extending away from the front plate and defining an end cap recess opposite the front plate and having an inner perimeter such that the end cap can be fitted over the alignment body and mated with the base portion;
• one or more second magnetic elements coupled to the end cap and operable to cooperate with the one or more first magnetic elements to magnetically secure the end cap to the base portion when the end cap recess is fitted over the alignment body;
• and
• a plurality of threaded holes spaced apart along an exterior surface of the sidewall;
• a plurality of motion capture markers coupled to the end cap, each motion capture marker in the plurality of motion capture markers comprising a post having a first threaded end that is coupled to one of the threaded holes in the plurality of threaded holes, a second end opposite the first end, and a motion tracker ball coupled to the second end;
• wherein at two or more of the plurality of motion capture markers have posts of different lengths.
