Developer Seeks Advice on Compact, Low-Center-of-Gravity Design for 3–5 kg Metal Robot Soccer Chassis
1 reports · 1 sources
A developer is converting a cardboard/wood prototype into a metal chassis, targeting a 3–5 kg class competitive mobile robot, and plans to first use a single base plate to mount 300 RPM Johnson motors and BTS7960 drivers. He is publicly asking for advice on two design questions: how a small 300 mm × 300 mm class metal robot can achieve a compact body and low center of gravity to withstand heavier opponents; and whether a 100% invertible robot should use a sandwich structure of base plate + standoffs + top plate, or a bent sheet-metal shell. He also hopes to get prototyping methods for converting the cardboard model into aluminum plate cutting and drilling dimensions and avoiding mistakes in the first machining attempt. There are currently no design conclusions or solution feedback.

- How to design a compact, low-center-of-gravity body for a 3–5 kg metal robot soccer chassis? Seeking advice
A developer is converting a cardboard/wood prototype into a metal chassis for a 3 kg–5 kg class competitive mobile robot, planning to first use a single base plate to mount 300 RPM Johnson motors and BTS7960 drivers. Their core questions are: how a small 300 mm×300 mm-class metal robot can achieve a compact body and low center of gravity to hold off heavier opponents, and whether a 100% invertible robot should use a base plate + standoffs + top plate sandwich structure or a bent sheet-metal shell. They also want prototyping methods for converting the cardboard model into aluminum plate cutting and drilling dimensions to avoid mistakes on the first machining attempt.
