The final setup looks like this:
Finally, we have been very busy putting the finishing touches and repairs on our robotic arm, SASHA 6.0, and have been working on a tentative project, SASHA 7.0. SASHA 6.0 will soon be equipped with the same Skype video chatting technology implemented on SASHA 5.2. Stay tuned for more updates on this!

The NASA project is where we will attach a camera onto a camera stand which we installed onto the top of our old vex robot, SASHA 5.2. This new robot is SASHA 6.1 and it is going to be used as our NASA rover. This is a very advanced project that will take a while to establish and place the camera stand ou top of our robot.
After we esemble the camera stand on top of the robot, we will use a phone as our camera. The phone will have Skype turned on so it can show us everything that is going on in front of our Mars rover. We'll have a computer turned on so we can see whatever the rover sees from our computer. We can even direction the rover without being right next to it if we have the camera attached, just like they do with.the actual Mars rover. The only difference will be that ours us not as advanced as theirs.

Our first robotic arm is finished. We completed the arm and it is fully functional aside from one converter which was overloaded and quickly replaced. The robotic arm is open to improvements, but currently it is in testing phase so that we can determine where these improvements will be.

The basic layout of the arena starts with the cardboard base. Each base is raised about six inches and has several holes in it for columns on which the "mines" (or balls) will be placed. There are a total of four platform, connected by wooden bridges making it challenging to get around. There is one platform, the entrance platform, which does not have any holes on it. It is purely for the purpose of entering the arena and navigating around it.
The structure looks like this:

Here are the places we currently use (hint: each image is a link):

1. Define the problem - our problem is that we need an arm by tomorrow.
2. Brainstorm - we thought about our old arm idea that had only one arm in the front of the vex robot and the second design of our robot were we had two arms.
3. Research and generate ideas - we researched ideas from looking at other groups ideas which were pretty much all by the book, and then we decided to make our own design for the arm and put it on the top of the robot.
4. Identify criteria and specify constraints- we had many constraints that held us back including that we can only use one brain for the initial and final design, because we are using two brains for the testing, but we will have to change it back when we are done.
5. Explore possibilities - we have had several possibilities for the arm/arms on SASHA 5.2. we have had one arm in the front of the robot, one arm on either side, and now an arm on the top.
6. select an approach - we have decided to go with one arm on the top of the vex robot.
7. Develop a design proposal - we are going to construct an arm on the top of our vex robot, SASHA 5.2, which will be better than either of the other designs and well attached with screws.
8. make a model or prototype - we are currently working on constructing our arm on the top of the robot.
9. Test and evaluate the design using specification - we are going to test our arm with the vex micro controller and try to pick up the either the green vex ball or a tennis ball.
10. Refine the problem - we have created an arm on the top of our vex robot that will be capable of picking up and carrying the vex ball/ tennis ball.
11. Create or make solution - we created the vex arm.
12. Communicate processes and results - we have clearly documented all work on creating this vex arm on top of our robot.
SASHA 5.1 had to be dismantled because we had two arms with two brains for our testing phase when we decided to go with two arms, one on the front, on on the back. Now we have decided that we would go back to one arm but change it from the front of our vex robot design and put it on to the top. SASHA 5.2 is clearly much better than SASHA 5.1 because now it is smaller, and easier to control.
As you can clearly see in the above image, we have constructed our arm on the top of our vex robot instead of two,one on the front and the back of the frame. You can also see that we constructed another frame to hold the arm in place that goes above the main body that holds the brain and the battery.

Through the mandated use of the Engineering Design Process, we've been able to overcome these, and continue on with the development of SASHA 5.1. The robot in it's latest form contains two arms, two brains, five motors, two transmitters, and requires two remotes to run. We believe that right now, we are done with all developments and that no further ones will need to be made.
The robot, SASHA 5.1, looks like this:
- Inability to pick up a ball (no arm)--This led to development of SASHA 5.1
- Inability to hold ball
- Lack of speed
- Lack of power
- Incontrollable arm
- Extremely unbalanced robot (this led to several developments/changes)
- Inability to turn
- Lack of controller ability to control the robot properly
As always, subscribe to our blog and stay posted for additional developments.

However, while this robot used to be SASHA 4.1, and was later upgraded to 5.0, it is now known as 5.1. We've done too much work on it for it to be the same as the old SASHA 5.0, the miniature drone-capable robot. It now has mine sweeping capabilities, two arms, and two brains. It is larger than we expected it to be, and it is definitely not as fast, versatile, or stealthy as the original. There is no way we could continue this construction without the robot being completely different from the original product, as our objectives have changed. Although it's not a brand new robot, this robot is definitely new. We may never see SASHA 5.0 again, but it'll always be a part of 5.1. These additions have put SASHA 5.0 past what we've ever imagined for it. Welcome to our lab, SASHA 5.1.

This crude sketch shows how the final robot will be arranged. There are two brains, and the other arm will be situated on the opposite side from the existing one. In addition to this, we will probably be outfitting the robot with all four wheels the same. The wheels we use will be the ones that are currently in the back (near the new arm's location). We'll continue to let you know how this development is coming, and keep you posted on all the progress we make.

At first, the wheels worked arcade style, so we had to change around the ports to get them to work tank style which is the style we prefer. The following images show our tests of the robot, including small adjustments made to better the robot, such as a small plate added in the bottom to hold the battery better.
- Special turning wheels from 3.0
- Moving arm from 4.0
- Possible small variety of Lego parts from 1.0 and 2.0
- Live video streaming capabilities from 3.0

We're taking a break from SASHA 5.0 to develop 4.1, a miniature robot that will use Robot C and might incorporate drone capabilities.
SASHA 4.1 will be a side project that will keep us busy while the considerations, planning, and building of 5.0 takes place.
|Our variety of parts, laid out for consideration|
|Tyler working with the aforementioned parts|
|We also use brand new parts from our VEX kit to complete our building|
|In addition to VEX parts, we will be using Lego Mindstorms NXT parts|
|All of them will come together in the hands of our builders|
Our group is working with a wide array and variety of parts, going to the deepest depths of our resources to create the tiny SASHA 4.1.
At the same time, SASHA 5.0 is not forgotten. We are working hard to produce 5.0 while also working on 4.1 at the same time. 4.1, since it is a miniature project, will be completed in much less time and therefore we are hoping to complete them simultaneously.
Also, finally, as promised, here is a copy of our presentation for the potential Robotics team members of next year. It displays the expertly crafted and designed SASHA 4.0, showing the work our group has been doing for the past few weeks.
