Shrinking the Hacksmith Orbitron BattleBot Right down to a 150g Antweight Machine

For geeky engineer varieties (we all know our readers), the BattleBot idea is among the most interesting “sports activities” possible. Operating round whereas holding a ball is boring athleticism. However designing and establishing robots that combat to dying in a contemporary televised Colosseum? That takes brainpower and fabrication ability, which turns into particularly obvious within the decrease weight lessons. In order for you some proof, check out Workforce Panic’s antweight duplicate of Hacksmith’s Orbitron.

Workforce Orbitron is a gaggle of scholars from Ontario, Canada’s College of Waterloo. In 2023, the huge Hacksmith Industries YouTube channel mixed forces with the group. The ensuing Orbitron BattleBot is a 250-pound behemoth that competes within the heavyweight class. Its distinctive weapon setup consists of two chain-driven vertical spinners, which flip over opponents. Orbitron even has autonomous functionality and may assault different BattleBots with out direct management from a human operator.

As a enjoyable solution to work together with followers, Workforce Orbitron launched a small 3D-printable scale mannequin of Orbitron. That may’t combat and even transfer underneath its personal energy, but it surely gave Workforce Panic the thought to construct an antweight model of Orbitron that may. Guidelines for antweight lessons differ, however Workforce Panic determined to stick to the everyday 150g weight restrict. That’s a few third of a pound, which is extraordinarily restrictive and difficult.

Just like the heavyweight Orbitron, this antweight Orbitron is a four-wheel drive BattleBot with two spinner weapons. 4 tiny DC gearmotors sit within the robotic’s 3D-printed plastic body to drive the wheels. Every spinner has a extra highly effective brushless DC motor, like what you’d discover on a small drone.

And that is the place Workforce Panic began to get intelligent with weight discount. The spinners and their motors connect to mounts constituted of PCBs. Not solely are PCBs sturdy, however this additionally eliminates some components. The spinners themselves had been fabricated utilizing PCBWay’s metal 3D printing service. That allow Workforce Panic design them to be very light-weight, but additionally sturdy.

Workforce Panic doesn’t specify the controller used for this construct, but it surely seems to drive the wheel gearmotors straight. The 2 brushless DC motors appear to have devoted miniature ESC (Digital Pace Controllers). Energy comes from a pair of itty-bitty lithium batteries.
