Micro Rover Final PCB Layout

By: Eagled’Or Am (Electronics and Control Engineer) After completing the final Eagle schematic, the next step is to switch to the board layout in order to design the PCB. Since space within the rover is limited, the size of the PCB had to possess dimensions less than 3.30” x 2.50” x 0.50” (L x W […]

Micro Rover Updated Schedule

By: Rafi Koutoby (Project Manager) Attached is the updated schedule for team Micro Rover. Due to the major change in design of the rover as a result of the new requirement of it being able to carry not just a Samsung Galaxy S2 (which we are utilizing as the main reference for our rover dimensions), […]

Micro Rover Final Eagle Schematic

By: Eagled’Or Am (Electronics and Control Engineer) Aside from the simple pin changes, the main difference between the final Eagle schematic and the preliminary Eagle schematic was that I was able to find the actual module for the 7805 voltage regulator and the SN755410 motor driver. Previously, I just drew the module as a placeholder […]

Micro Rover Updated Interface Definitions

By: Eagled’Or Am (Electronics and Control Engineer) Displayed below is the final Interface Definitions created for the Micro Rover. After a series of tests with the components and additional trade-off studies conducted, there were a few changes made to some of the components and the pins. The original interface definitions can be found here. As […]

Micro Rover Final System Block Diagram

By: Sherman Xa (Mission, Systems, and Testing Engineer) After much discussion with the team and Professor Hill, we had made a significant number of changes to the original Micro Rover project. One major change that we altered was the chassis, which is planned to be an expandable chassis to incorporate different compatible devices that are […]

Micro Rover Selected Motor Driver

By: Eagled’Or Am (Electronics and Control Engineer) Previously, a motor driver trade-off study was conducted comparing a variety of motor drivers. The motor drivers compared were the L293D, the L293B and the L298P. These motor drivers all had certain characteristics that made them a good choice to be the motor driver for our Micro Rover. […]

Micro Rover Motor Driver Trade-Off Study

By: Eagled’Or Am (Electronics and Control Engineer) In order to protect the motor driver from the inductive kick produced by the motors, it is preferable to include diodes in order to protect the motor driver and other components. When we were choosing the components, we did not account for the addition of diodes because Mini […]

Micro Rover Updated Design and Dimensions

By: Ahmed Abanumai (Manufacturing Engineer) The customer desired to add a new feature to the rover in which he wanted the rover to be cut in half and be adjustable, hence creating a ‘universal chassis.’ The main advantage of this design is that the user would not be restricted to a Samsung Galaxy S2 (like […]

Micro Rover Preliminary Eagle Schematic, Fritzing Diagram, and PCB

By: Eagled’Or Am (Electronics and Control Engineer) The purpose of this Eagle schematic is to recreate the interface definitions in a way that will help visualize how the components are interacting. The program used to create this schematic is CadSoft Eagle Light Version 7.2.0. It can be downloaded for free through this link from CadSoft Computer. When […]

Micro Rover Arxterra and Code Implementation Test

By: Sherman Xa (Mission, Systems, and Testing Engineer) As we are reaching the end of the design and planning stages of our Micro Rover project, we are entering the testing stage. The first assignment is to implement the old Mini RoSco code and learn how they operated between Arxterra Control Panel and the Arduino microcontroller. […]
