After researching hardware implementations and control algorithms we designed our first revision crissioned Zeus (after the shocking results expected). Zeus was designed to have motor control circuitry, input protection, and all the required voltage regulation. The four banks of headers also allowed the Zeus to be sandwiched directly to the microcontrollers developer board. https://images.squarespace-cdn.com/content/v1/5e62bdb31932850372b98951/1584221694945-QBNST4CNXE4WBZDX60VR/zeus_pic.jpg Zeus - Motor Control Tobias Keene, D.D.S. Hailing from Richmond, Virginia, Dr. Tobias Keene brings a bit of unabashed Southern hospitality to all his patients. He moved to Washington, D.C. over thirty years ago as a freshman at Ivy College. Right after graduation, he attended World University’s School of Dentistry. Before opening Keene Dental in 1994, he worked for free clinics and some of the finest practices in the District. He is part of the 123 Dental Association and stays up-to-date on the latest dental discoveries. When not striving to keep his patients happy and healthy, he’s enjoys hiking with his family in Rock Creek Park. https://images.squarespace-cdn.com/content/v1/5e62bdb31932850372b98951/1584221800503-AGOPLPQR4T77QUX6K365/zeus_pic.jpg Zeus - Voltage Regulation As Zeus was designed to work with input voltages between 24 and 48 volts, the voltage regulation needed to create 12, 5, 3.3, and 1.2 volts. https://images.squarespace-cdn.com/content/v1/5e62bdb31932850372b98951/1583539721948-VY8D3H7ODZN94EK4EJ6L/IMG-20191213-WA0001.jpg Zeus - Input Protection Zeus employs a hot swap controller to limit the inrush current created by the large capacitance. The hot swap also acts as a resettable fuse providing protection from hardware and human caused shorts. The use of lab power supplies with their internal current limiters released some black smoke back to the aether as shown. https://www.faustoem.com/kevin daily 0.75 2024-02-26 https://images.squarespace-cdn.com/content/v1/5e62bdb31932850372b98951/1585237977591-I76PXXHZBD2NE2UF5THU/cropped_personalpage.png About Kevin - Kevin Heyer I am an electrical EIT and recently graduated from British Columbia Institute of Technology with a bachelors in Electrical Engineering and a diploma in Mechatronics and Robotics. I have a passion for all things hardware and low level programming such as FPGA’s, PCB design, and embedded programming. I worked for two years assembling and testing PCBA’s, a summer designing and testing PCB’s for Zaber Technologies, and a semester working as an assistant lab instructor at BCIT. https://www.faustoem.com/hades daily 0.75 2020-06-13 https://images.squarespace-cdn.com/content/v1/5e62bdb31932850372b98951/1584222382172-FE3AQDZ7UZ2DO9GBXB1Z/What-is-EtherCAT-1.png Hades - EtherCAT The hades revision has integrated EtherCAT communication for real time capabilities with higher bandwidth. The communication also allows for the devices to be connected in series to allow one master device to control multiple actuators. The RJ45 connection also introduces isolation between each motor driver ensuring communication. https://images.squarespace-cdn.com/content/v1/5e62bdb31932850372b98951/1583535118661-NBVMDGADGLAE8FFCZN63/hades_pic_bot.png Hades - Motor Control Hardware Tobias Keene, D.D.S.

The board also includes resettable input protection, voltage regulation, CAN, and interfaces to our custom encoder board. https://images.squarespace-cdn.com/content/v1/5e62bdb31932850372b98951/1584222159573-7TTAGFR4RKLZPAL2XEVD/micro_map.png Hades - Microcontroller The microcontroller used is the TMS320F28379D which is specifically designed for motor control applications. It features a 200MHz dual core with 16 bit 1MSPS and high resolution PWM. This gives a sizable of headroom allowing us to run the motor control loop at 40kHz while also using a real time operating system to handle communications, safety systems, and various housekeeping. https://images.squarespace-cdn.com/content/v1/5e62bdb31932850372b98951/1584222250677-39H9K7T7Y3AB5M8MU4O8/image-asset.jpeg Hades - Current Status After the mess of delays caused by COVID-19 we have finally been able to start assembling and testing Hades. As of the beginning of June we have started testing the voltage rails. https://www.faustoem.com/our-story daily 0.75 2020-03-07 https://images.squarespace-cdn.com/content/v1/5ce6d339a8ffbf0001a8fb20/1560446521854-TDUPBZUSA14IJEXD2N03/plant-textures-2.jpg About Us https://www.faustoem.com/mechanical daily 0.75 2020-03-26 https://images.squarespace-cdn.com/content/v1/5e62bdb31932850372b98951/1585236343906-RPLRTWWIDJMPG1N9HIX7/secondJoint.png Mechanical - 3D Printed Joints The mechanical design is centered around 3D printing as this is more readily accessible to students and hobbyists. The goal of the mechanical design is to provide effective gearing without introducing backlash. The current design is a 3D printed nylon cycloidal gearbox with a 22:1 gearing ratio. https://images.squarespace-cdn.com/content/v1/5e62bdb31932850372b98951/1585238891539-NBIG8YIG6SMZOC95LT6M/gearbox.png Mechanical - Gearbox Tobias Keene, D.D.S.

Maybe you want to launch a business. Maybe you want to turn a hobby into something more. Or maybe you have a creative project to share with the world. Whatever it is, the way you tell your story online can make all the difference. Don’t worry about sounding professional. Sound like you. There are over 1.5 billion websites out there, but your story is what’s going to separate this one from the rest. If you read the words back and don’t hear your own voice in your head, that’s a good sign you still have more work to do. https://www.faustoem.com/user-interface daily 0.75 2020-03-09 https://images.squarespace-cdn.com/content/v1/5e62bdb31932850372b98951/1583795551006-I4ILMU0GI39LZJ5LOOS6/UI_Nothing.png User Interface - Custom Designed Designed from the ground up in order to meet all the configuration and troubleshooting.
