MechaCanvas is a browser studio for building real robots. Pick from 41 official URDF models (24 humanoids, 16 arms, a quadruped) or import your own URDF/USD, pose joints in a 3D viewer, wire sensors and servos on a virtual breadboard, and program behaviors with blocks. The same behavior runs in the in-browser simulator and can stream over Web Serial to an ESP32 runtime or ROBOTIS/Feetech smart servos. No install, 8 languages.

GPT-6 Astra Challenge

What real task does your product handle with GPT-6 Astra?

Maker

GPT-6 Astra acts as the engineering intelligence behind our robotics development workflow. A user can describe the robot they want to build in natural language, and Astra translates that intent into a structured robot architecture. It reasons across motors, drivers, sensors, controllers, power requirements, communication protocols, and software constraints; identifies incompatible components; suggests alternatives; and helps generate wiring, firmware, control logic, and deployment steps. Instead of simply generating robotics code, Astra works with our hardware constraint system to help users move from an idea to a physically feasible robot design. The real task is turning human intent into an engineering-valid robotics system that can progress from hardware selection to simulation and eventually deployment on real hardware.

Hi everyone, maker here! I built MechaCanvas for a hackathon because getting from "I have a robot idea" to "a motor actually moved" usually means installing ROS, a CAD tool, a simulator and a firmware toolchain first. I wanted all of that to fit in one browser tab. What you can try right now, no sign-up needed for most of it: - Open the robot library and load a humanoid or arm (all official URDFs from Unitree, ROBOTIS, AGIBOT, LimX, Franka, UR and more) - Drag joints in the 3D viewer and save motion steps - Wire an LED, sensor or servo on the virtual breadboard and see the circuit checks - Snap behavior blocks together and run them in the simulator - Import your own URDF or USD model The hardware path (ESP32 runtime and ROBOTIS/Feetech servos over Web Serial in Chromium) is the newest part and still being tested on physical motors, so feedback there is especially welcome. Which robots or parts should I add next? Happy to answer anything.
