Here are some pictures as we continue work on our new Mars Rover.
Apprentice Machinist Lunamoth uses the vertical mill to modify an aluminum part for the Mars Rover. Cutting, drilling, and machining metal is Lunamoth’s favorite area of work. She is turning into a good machinist.
Lunamoth uses our mini drill press to drill holes onto the metal wheels in preparation for tapping the threads.
A new skill: Lunamoth uses our largest Milwaukee drill to tap 6-32 threads into the holes she drilled into metal wheels. The threaded holes will be used to secure the tread to the wheel (we don’t like glue). Tapping threads is very tricky (it’s very easy to snap the tapping bit), but she does a splendid job.
Lunamoth mounts a side-firing sonar sensor on the the rocker-bogie suspension system. She’s done most of the mechanical construction on the robot.
Lunamoth feeds the wires through the chassis tube.
After fishing the wires through the chassis tubes, Lunamoth solders the power, ground, and signal wires to the sonar sensors.
Lunamoth uses the electric heat gun to complete the heat shrinking on the wires she just soldered. (Red nail polish is optional when heat shrinking in our workshop, but always a plus!)
Slowly but surely, we’re making progress. We’ve completed all the wiring and soldering for the sonars, motors, and servos on the chassis, and we’ve assembled and installed the wheels. We sill need to complete the rover’s top, install the solar panels, build the mast head, and many other elements. Stay tuned.
