Our Robot

During the summer we came to summer robotics camp to build a robot, that we used to practice building. Our chassis was made of 288 channel on each side and a 160 channel at the front. We used 2 flat plates at the middle to hold the expansion hub the reason we choose to put the hub in the middle was because it allows us to balance out the weight. Also allows us connect all motors with out worrying about the wire being to short. We have a motor powered arm with a servo going through the middle of the robot with 2 motor controlled regular wheels and 2 omni wheels not controlled by motors. These are passive motors. We used Textrix parts. This is a training design model created and used for coach training at UTD by Patrick Michaud.

This is our Scrimmage robot. We chose was a "A" chassis frame that is made out of 288" channels with 4 motor driven wheels and 2 omni wheels at the front for better mobility. We put the expansion hub at the back since we have most of our motors there and that would allow us to connect them with out having troubles with the wires. We also added flat plates as pushers at the front and the back. For the arm, we used a 150" channel and flats at the end with inside corner plates to attach to the hand that allowed us to garb the minerals. We used a servo to move the arm but the servo was too small and didn't move. We had foam in the rear of the robot to help get up the craters easily. We used Textrix parts.

Design

For the Rover Ruckus robot, we decided to switch to Rev Robotics parts because we were having issues with the Tetrix gear systems. For our new chassis we had trouble choosing which design would fit since we wanted to have a collector at the front of our robot. We were going to use a gear system with rubber bands tied to it so it could gather the minerals but we decided to scratch that idea because it was too complicated. Besides, we didn’t want to get stuck in the crater and didn't have enough time to waste. At the beginning we focused on the robot more than the attachments because we realized that we would need to build up to help balance out the weight. There are traction wheels at the back and 2 omni wheels at the front for better movement. For this robot we had to use 2 expansion hubs for two existing and one future attachments, two sensors, two batteries, three servos, and three motors.

Strategy

We built a linear actuator lift and claw attachment to lift our robot from the ground and hang from Lander for 30pts and latch at the end game for 50pts. We added a front Pusher to push the minerals into the Alliance Depot for 2pts each. We designed and built a 3D Marker and Marker Placer for an extra 15pts. We used TinkerCAD to create the Marker. This gives us a range total of 125-150 points. We made cascading slide with a scooper that is moved with servos we are going to this attachment to get minerals from the crater to then move them to the depot
