) A two degree of freedom robot leg as described in lecture has limb length characteristics: l1 = 0.49 m = length of limb 1 between hip and knee l2 = 0.54 m = length of limb 2 between knee and foot The rotational joint angles are currently set at: Joint angle θ1 = 65 degrees = angle between limb 1 and horizontal (at the hip) Joint angle θ2 = 18 degrees = angle between limb 2 and the straight-ahead direction of limb 1 (at the knee) Given the information provided above, find the (xF, yF) coordinates of the foot. That is, find the x coordinate of the foot designated as xF and find the y coordinate of the foot designated as yF with the given setting of the joint angles and given limb lengths.
11) A two degree of freedom robot leg as described in lecture has limb length characteristics:
l1 = 0.49 m = length of limb 1 between hip and knee
l2 = 0.54 m = length of limb 2 between knee and foot
The rotational joint angles are currently set at:
Joint angle θ1 = 65 degrees = angle between limb 1 and horizontal (at the hip)
Joint angle θ2 = 18 degrees = angle between limb 2 and the straight-ahead direction of limb 1 (at the knee)
Given the information provided above, find the (xF, yF) coordinates of the foot.
That is, find the x coordinate of the foot designated as xF and find the y coordinate of the foot designated as yF with the given setting of the joint angles and given limb lengths.
