I've copied the game state from your screenshot into DriftingDroids:

The latest released version (1.3.7) of DriftingDroids finds a 9-moves solution, because it doesn't allow the red robot to move straight to the goal:
1: ↑ red North
2: ← red West
3: ↓ red South
4: ← red West
5: ↑ red North
6: → red East
7: ↓ red South
8: → red East
9: ↓ red South
However, the latest code change (commit 67057cf, implemented in response to issue #13) allows the program to find two 7-moves solutions, with the red robot moving straight to the goal:
1: ↓ yellow South
2: → yellow East
3: ↓ yellow South
4: ← yellow West
5: ↓ green South
6: → yellow East rebound
7: → red East
1: ← red West
2: ↓ green South
3: ← green West
4: ↑ green North
5: → red East rebound
6: ↓ green South rebound
7: ← red West
So, the issue you've reported is not a bug nor a missing feature of DriftingDroids. Please make sure that your program uses the latest code of the DriftingDroids solver.
OK, so this is the same problem as solved in #13. Now I remember: I tested in Roboyard 7.1 which still uses the solver without that fix.
sorry the bother again.
I hope I will soon be able to implement the board-setting im/export into Roboyard ;)
This puzzle is solved best in 7 moves, but the solver only finds a solution with 9
I guess it ignores a solution, where the red uses the staight line to the goal
