Robot Tank V2

thingiverse

I redesigned the Arduino Robot Tank by velli. My only issue was that the plastic grinding against plastic caused it to overheat and lock up at high speeds. To resolve this, I modified a version using 608 bearings for a buttery smooth ride. Here are some details about each part: * robot_bottom_rpi_motor.stl: This is the bottom section of the robot with mounting points for the Raspberry Pi 2 and motor driver. * robot_top_solid.stl: This is a solid top piece with no mounting points for any components. * waveshare_camera_mount.stl: This only fits the Waveshare RPi camera. * robot_top_batter_and_charger.stl: I designed this to work with the ESKY000152 charger, which can be found on eBay. It also accommodates a 2-3 cell Li-Po battery pack from HobbyKing. I created new parts that improve performance: * wheel_608_bearing.stl: This wheel design features a place to embed a 608 bearing and has been widened for better stability. * wider_track_link.stl: These track links are designed for the wider wheels and provide improved traction. * Wheel_cover_608_bearing.stl: This part covers the outside of the robot and plugs into the bearings on the wheels. * motor_mount_608_bearing.stl: I created this mount to hold the motor in place, with a spot for a 608 bearing. I also made a few modifications to existing parts: * Motor_cover.stl: This is the original part from velli's design. * robot_bottom_rpi_arduino_motor.stl: Similar to the previous version, but with two additional Arduino Nano vertical mounts. Print Settings: * Printer Brand: Printrbot * Printer Model: Printrbot Simple Metal * Rafts: No * Supports: No Important Notes: The wheel_608_bearing.stl part requires supports touching the build plate. It's best to print this part at a 0.1 layer height and 70-100% infill. The other parts can be printed with your desired settings.
