Motor locking mechanism including memory alloy wire

A stabilization system comprising:

• a payload;
• one or more locking systems, each of the one or more locking systems including:
• a motor configured to adjust an attitude of the payload, the motor comprising a stator and a rotor configured to rotate relative to the stator;
• a sliding structure capable of engaging the rotor to lock the rotor;
• a memory alloy wire configured to engage the sliding structure to exert a first force to move the sliding structure in a first sliding direction from a first position to a second position when electrical energy is applied to the memory alloy wire, where the applied electrical energy causes the memory alloy wire to shorten, the shortening exerting the first force to cause movement of the sliding structure through the engagement of the memory alloy wire with the sliding structure;
• and
• a restoring structure to engage the sliding structure to exert a second force to move the sliding structure in a second sliding direction from the second position to the first position.
