Glenn High School Capstones
Simulated Lunar Operations
Celestial bodies such as Mars or the Moon offer very little or no atmosphere that would enable rovers to utilize conventional wheels that we use on Earth. Researchers at the Simulated Lunar Operations (SLOPE) facility develop innovative airless wheels that can navigate lunar and Martian terrain including loose granular soil, dense high shear strength soil and a bedrock-like material.
Capstone Summary
For this capstone, students will design and fabricate a wheel that does not inflate and can function in an environment with little or no atmosphere. Students must fabricate a five (5) inch diameter replica of the current Mars Curiosity Rovers in order to collect baseline data for comparison of results of their wheel design. Student designed wheels must not exceed five (5) inches in diameter and perform on dry sand over six (6) feet on a grade of seven (7) degrees while carrying as much weight as possible. Wheels will be evaluated by vehicle motion generated by traction forces only. Any motion generated by propulsion forces observed by “kicking up” sand will not be considered.
Test Rig Components and Specifications
Test Vehicles may be commercially purchased. It is recommended that motor specifications include a 75:1 gearbox, voltage range or 2 – 7.5 Volts, stall current of 6.6 Amps @ 7.2 Volts, no-load current for 420 mAmps @ 7.2 Volts per motor, no-load output shaft speed at 7.2 Volts, and stall torque at 7.2 V of 11 kg-cm (160 oz-in) per motor. The test vehicles should utilize a microcontroller board as a general-purpose dual motor driver.
