Un-Flippable Rover

AutoCAD Blueprint Guide: Un-Flippable Rover I have generated a 3D conceptual render of the robot for you (you should see it right in our chat window!). Notice how the wooden chassis is sandwiched entirely between the diameter of the giant rubber wheels. This is the secret to the un-flippable design. If the robot rolls over, the electronics never touch the ground; only the wheels do! Here are the exact dimensions and layout rules you need to follow when drafting your 2D/3D models in AutoCAD or SolidWorks: 1. The Core Chassis Dimensions You will need to cut two identical rectangular plates of plywood. We will use standoffs to separate them (creating a "hamburger" effect to hide the heavy batteries inside). Length: 250 mm (25 cm) Width: 150 mm (15 cm) Thickness (per plate): 5 mm or 8 mm plywood. (Make sure to fillet/round the 4 corners in AutoCAD so they don't catch on rocks). 2. Motor Mounting Holes (The Most Important Part) You are using four 12V Side-Shaft DC Motors. They need to be mounted underneath the bottom plate. Wheelbase (Distance between front and rear axles): ~180 mm. Mounting Brackets: Leave four rectangular footprints (approx 30mm x 30mm) near the 4 corners of the bottom plate. Drill holes for standard L-brackets to mount the motors securely to the wood. 3. Dedicated Electronics Placement (Top Plate) The top wooden plate is your "Dashboard." You need to draft mounting holes for the following components so you can screw them down securely: Dead Center: The ESP32-CAM & L298N Motor Driver. Draft a 50mm x 50mm footprint in the absolute center. Front Edge (Center): The Camera Mount. Leave a 25mm x 25mm slot at the very front to mount a small L-bracket that holds the ESP32 camera lens facing forward. Front Edge (Left & Right): The Sensors. Draft two circular zones (approx 20mm diameter) on either side of the camera for your MQ-135 and MQ-2 Gas Sensors to point forward and sniff the air. Dead Center (Underneath): The MPU6050 Gyroscope. It MUST be placed exactly in the center of the robot's physical mass to correctly calculate flips and gravity. 4. The Internal Payload (Sandwiched Area) Between the top wooden plate and bottom wooden plate, you will place metal standoffs (approx 35mm tall). In this "sandwiched" area, you will store: The Heavy Battery Pack: (Draft a 75mm x 40mm box for the 18650 holder). The Buck Converter: (Draft a 45mm x 20mm box). Placing the heavy batteries at the bottom lowers the center of gravity, making the robot less likely to flip in the first place! AutoCAD Next Steps: Draw the 250x150mm rectangle. Place the four motor brackets. Draw a side-profile view to verify that your chosen wheels (e.g., 100mm or 130mm diameter) will extend above the top plate and below the bottom plate.
