By Mason Nguyen, Project Manager and Elaine Doan A hexapod is a six legged robotic capable of moving in all six degrees of freedom forward/backward, left/right, up/down with the combination of pitch, roll, and yaw rotations. The objective is to deliver a hexapod that will need to operate safely during class room demonstration, capable of […]
By Maxwell Nguyen Along the designated course shared by the Rover, Spiderbot, and Hexapod, the most notable obstacle was a sprinkler head with the height of four inches. The orginal Arxterra RoSco is design to travel primarily through flat surfaces and is not equipped to move over obstacles at such height. In order to clear […]
By Chau To Optoisolator is a component that transfers the signal between 2 isolated circuits. It consists of an LED and a phototransistor as shown in (Figure 1). When a signal is applied at anode (cathode is usually connected to ground), the LED will emit light that shines on the base of the phototransistor turning […]
By Mustafa Alkhulaitit – Project Manager Up to this point, our team has been working on two main features of the 3D printer: the frame and the heat bed. After receiving the frame, our team has started assembling it and getting it ready to transfer the electronics to the new frame. The frame needed multiple […]
By Maxwell Nguyen, Project Manager The rover team is researching new ideas for treads/tracks for the rover. The current tread belt is one continuous belt that takes hours to print. In addition, one small mistake could potential ruin the entire track and make it completely useless. In order to fix this problem, we will be […]
By Mustafa Alkhulaitit, Project Manager While waiting for the frame to be cut and ready for installation, our group has taken a step to save time and minimize any delay due to certain circumstances. The first upgrade that the advanced 3D printer team started working on was the LCD controller. We thought this upgrade was […]
By Tuan Vo, Project Manager Material of aircraft: To build the body of the aircraft, we have decided to go with plastic foam. A 12”diameter X 4”high wheel of foam weighs in at 98grams. We will cut the foam to mount the fans and components using a hot knife. In this project, one of the […]
By Tuan Vo, Project Manager Battery: When picking the battery, three requirements must be taken into consideration. 1) the battery must have enough power to run the fans for the required amount of time. 2) the discharge rate must be high enough to provide the fan with required current to operate. 3) weight must be […]
By Tuan Vo, Program Manager Introduction: Weight is the number one factor when determining our components that will be used on our aircraft. As stated in the Preliminary Design Document, we decided to use the fans and speed controllers given to us. Purpose: To identify and expatiate on the equipment and materials selected for the […]
