NASA SPEED challenge V1 · 模型 57222
Ejection system for NASA capsules using SPEED guiding vehicle. By exchanging capsule bottom support and adjusting the height of release cylinders and M14 lock screw, any of given NASA capsules can be mounted. The ejection system is considered to receive 5V signal to Arduino Nano and then transfer the signal to NEMA 17 motor (has its own power supply), which rotates 18 degrees counter clockwise, unlocks outer shaft, and by spring action it shoots upwards capsule bottom support and CAPSULE. Simultaneously, it unlocks upper lock mechanism which disassembles as soon as it leaves SPEED vehicle. All parts can be 3D printed except spring and inner shaft which must be machined. Other standard parts such as screws, nuts, bearings can be bought. Insulated housing for the NEMA 17 motor, battery and Arduino is not made at the moment, but is considered space wise.
