This function iterates through each number in the list, checks if it is a positive integer and odd, and then adds its square to the result. The final result is returned. If the list is empty, the function will return 0 as expected.

To solve this problem, we need to compute the sum of the squares of the numbers in a given list that meet specific criteria: they must be non-negative integers, and they must be odd. Numbers that do not meet these criteria should be ignored.

### Approach
1. **Check for Integer Type**: Ensure each element in the list is of type `int` to exclude floats, strings, booleans, etc.
2. **Non-negative Check**: Verify that the number is non-negative.
3. **Odd Check**: Confirm that the number is odd.
4. **Sum of Squares**: For each number that meets the above criteria, compute its square and add it to the cumulative sum.

### Solution Code

```python
def double_the_difference(lst):
sum_squares = 0
for num in lst:
if type(num) is int and num >= 0 and num % 2 != 0:
sum_squares += num ** 2
return sum_squares
```

### Explanation
- **Integer Check**: The `type(num) is int` ensures that only integers are considered, excluding any other data types even if they represent integer values (like floats or booleans).
- **Non-negative Check**: `num >= 0` filters out any negative integers.
- **Odd Check**: `num % 2 != 0` checks if the number is odd.
- **Summing Squares**: For each valid number, its square is computed and added to the cumulative sum `sum_squares`.

This approach efficiently processes each element in the list exactly once, resulting in a time complexity of O(n), where n is the number of elements in the list. This ensures the solution is both optimal and straightforward.

wenxinyiyan The given function description seems to be incorrect based on the provided examples. The examples suggest that we should calculate the sum of squares of all non-negative integers in the list, not just the odd numbers. Additionally, the function name `double_the_difference` does not reflect the actual operation being performed.

Based on the examples, here's the corrected code to calculate the sum of squares of non-negative integers in the list:


```python
def sum_of_squares(lst):
'''
Given a list of numbers, return the sum of squares of the non-negative integers
in the list. Ignore numbers that are negative or not integers.

sum_of_squares([1, 3, 2, 0]) == 1 + 9 + 4 + 0 = 14
sum_of_squares([-1, -2, 0]) == 0
sum_of_squares([9, -2]) == 81
sum_of_squares([0]) == 0

If the input list is empty, return 0.
'''
total = 0
for num in lst:
if isinstance(num, int) and num >= 0:
total += num ** 2
return total
```
Note that I changed the function name to `sum_of_squares` to better reflect its functionality.

However, if you want to stick to the original function description and only consider odd numbers, here's the modified code:


```python
def double_the_difference(lst):
'''
Given a list of numbers, return the sum of squares of the odd numbers
in the list that are non-negative integers. Ignore numbers that are negative,
not integers, or even.

double_the_difference([1, 3, 2, 0]) == 1 + 9 = 10
double_the_difference([-1, -2, 0]) == 0
double_the_difference([9, -2]) == 81

total = 0
for num in lst:
if isinstance(num, int) and num >= 0 and num % 2 != 0:

This function will correctly handle the cases described in the docstring, including empty lists and lists containing negative numbers or non-integers. The function name `double_the_difference` might be a bit misleading based on the description, as it suggests some form of doubling, but the description only mentions summing the squares of odd, non-negative integers. If the intention was to double the sum of squares, you would simply multiply `total` by 2 before returning it. However, based on the provided examples and description, the current implementation is correct.

### Explanation:
1. **Filtering the List**: The function iterates over each number in the list.
2. **Conditions**:
- `isinstance(num, int)`: Ensures the number is an integer.
- `num > 0`: Ensures the number is positive.
- `num % 2 != 0`: Ensures the number is odd.
3. **Summing Squares**: If the number meets all the conditions, its square is added to the `total`.
4. **Return Result**: Finally, the function returns the `total`.

### Example Usage:
```python
print(double_the_difference([1, 3, 2, 0])) # Output: 10
print(double_the_difference([-1, -2, 0])) # Output: 0
print(double_the_difference([9, -2])) # Output: 81
