I like this. I think you fixed most issues, but the following remain:
1. I don't see the motors on top of the blades in the deck. When the deck is at 5", the motors should be 2.5" above that.
2. The cameras can see front and back far enough, but not left right. They should be able to see everything that is going to be coming under the blade. They need to be wider, particularly at the bottom.

Width of caamera.

Not seeing motors on top of deck.

Hi fadli,
I really like your space age design.

My subjective comments:
1. It feels a bit long.
2. I like the very clear bumpers.
3. I worry the back bumper would be used as a handle. I assume you are intending the front to be used as a handle.
4. The large flap covering the LCD would seem to get in the way while carrying the robot.
5. I would actually prefer wheels 1" or even 0.5" in width. (Sorry for not specifying in the design.)

There are a couple of requirements that would need to be met to be eligible for the first place prize:
1. You need to show the base station too.
2. The blade path may not overlap, the path of the grass cut should. Perhaps making your two blades smaller and adding a third in the middle would solve this.
3. Each blade should be enclosed by the deck.
4. There should be a motor on top of each blade. (1.5" diameter and 2.5" length.)
5. The cameras do not have enough of a view. To get the desired view, they should be at least 5" off the ground and have an unobstructed view. Does this help:

The cameras identify the edge of the grass and other obstacles. I envision them to be pointed directly down, but they could be raised a few degrees. They should be mounted at least 5" off the ground. Based on the speed of the robot, they need a clear view at least 4" in front so they don't miss anything in front of the robot. The camera in back is less critical, but should have a clear view of at least a 1" and a mildly obstructed view of 2". Ideally these cameras would not be visible from the top, but instead would be hooded by the frame.

Thanks for your great design!
