The key fob that came with the receiver has 4 buttons, and we plan on having each button control all servos at once. The four buttons will control the forward, backward, left, and right movements of the spider. We also ordered about 30 micro bearings which recently came in. Although, we are still waiting for the servos we ordered to arrive. We need the dimensions of these servos in order to submit our final design of the spider to be 3D printed. Another post with the final designs of the spider, the coding for the spider, and other updates on the project are soon to come.

Update on items purchased and other info
The group met earlier this week to further discuss the project, and to start the programming of the spider. Our RF M4 Reciever, 315MHz momentary type, recently arrived and we made a quick video to demonstrate how it will work. The receiver is connected to the breadboard, which uses the arduino board as the power source, and we have each button light up an LED.

Wireless Controller and information update
After a long duration of research and thought, we have come to the decision of adding a wireless controller to the spider. This wireless controller will be purchased from the website adafruit and is already programmed. This will make the setup of attaching it to the spider simple. The parts are shown below. they are labeled as a simpler RF M4 receiver.
Second we would like to give some sources on the board we will be using. As said before it is a Servo-pod by New Micros, Inc. The link to the website can be seen below. The specifications and features of this board make it a prime candidate for motion controlled designs and can be seen on the website by following the first link. The programming we plan to use is isomax. Some information on it can be read about on the second link.

Spider Update
The design of the spider has been further completed and the legs are now included. A bottom and side view of the spider can be seen below.
The legs will use six more servo motors to move it forward and backwards. 15 servo motors were purchased and will be used to move the spider. One of the problems that we ran into however was that the volume of the parts required to fully construct the spider are a bit more than the available material. We will be looking for a solution to this problem and may end up purchasing more material to accommodate for it.
Our first part was 3D printed on Wednesday 11/20. There was a problem with the printing due to it printing the wrong part at first. This set us back a few hours, although the correct part was printed out soon after. A few pictures of the part can be seen below. The servo was placed inside to test if it fit and it was a snug fit.
To be done in the future is further modeling of the parts in solid works which then need to be printed. The board that we are using is the servopod and the programming language is isomax. This code is going to be completed soon after the part if not at the same time. The whole group was present on Wednesday for over an hour completing parts, printing, and discussing the project as it is now and future ideas.
Another post updating the progress of the spider will be in the near future. We will have solid parts of the legs and more to come.

Initial spider concept and idea
The basic idea of the spider and its movement has been hypothesized. We are attempting to have the spider behave in a way similar to that of a cockroach. This movement is done with 6 legs in which 3 move in a upwards and forwards direction while the other 3 move down and backwards. This group of three legs are located on the creature as follows, the two outside legs on one side and the middle leg on the other side In order to visualize this a video of a cockroach walking can be shown below.
This behavior of walking was analyzed and mimicked to create a mechanism that will allow this movement. Specifically a frame is needed to hold 6 servo motors. The servo motors will move the legs forward and baakwards while the frames moves the motors up and down. This can be seen in the animation shown below.
This view of this previous animations is with a perspective displaying the bottom of the spider. Another view of the animation showing the mechanism that specivically raises each motor up and down is shown in the next animation below.
The whole team was present on Wednesday for about an hour discussing the overview of the project, what to be done next, generating prototype parts for the spider, and possible materials that need to be purchased.
A blog post displaying the prototypes of the parts, time spent working on the project of the members, and a further update in general of how the project is going and where to proceed is soon to come.
