Sal's RiSE Tests

Static Test

  • RiSE is powered and holding motors using position control (Under the RiSE Force Control Mode)
    • Tripod configuration with the wings at 45 degrees
    • Crank at zero degrees
    • Wing and Crank gains: Kp = 10, Kd = 0.5
    • Front right, middle left, back right feet touching
    • Tail is also in contact
  • Wall is at 40 degrees from horizontal
  • Using sticky feet (EarlyFootDesigns)
  • The wall surface is Xerox printer paper

  • Recorded the forces for each foot as:
  X Y Z
Front-right 0.78 N -2.53 N -1.87 N
Middle-left -1.83 N -9.46 N -8.61 N
Back-right 0.60 N -6.67 N -6.37 N

  • Additional two static tests
  • Except the tripod was reverse to measure the Middle-right foot
  • Only right feet were measured
  • Feet have been cleaned since Aug 9, trial
  • Recorded the forces for each foot as:
  X Y Z
Front-right 0.88 N -1.81 N -1.73 N
Middle-right 2.25 N -9.64 N -9.89 N
Back-right 1.76 N -10.68 N -7.92 N

  X Y Z
Front-right 1.13 N -2.78 N -2.58 N
Middle-right 2.38 N -9.19 N -9.83 N
Back-right 2.31 N -8.59 N -7.79 N
  • Note: the Middle-right foot is going to have reversed forces in the X-direction from the Middle-left foot data

  • Series of statics tests
    • Six feet each (except the data was lost from two front foot trials)
    • Right feet only
    • Quick cleaning of feet using rubbing alcohol
