Robosavvy found so many fresh ideas for their new humanoid robot design from GrabCADrs. This design is supposed to look great, be agile, and give for entertainment and educational value to users, a worthy Challenge that our Community was eager to solve. They are now set to launch this new open-source humanoid robot with hopes of making it at a reasonable cost.
Why is RoboSavvy focusing on this mission?
Comparable education and research humanoid robots cost over $10,000 due to their plastic molded shell parts, expensive actuators and closed-source business approach. They want this to be an open-source robot that will outperform its rival platforms while keeping the cost of materials to about $1,000. They will achieve this by utilizing materials and fabrication methods available to anyone. Materials include aluminum sheet and 3D printed parts for structure, vacuum formed polycarb exterior shell, servos for actuation and low cost electronics including Raspberry Pi for brains.
The RoboSavvy team expects to do some modifications, incorporating ideas from the full-range of winners, with the chosen design as the main inspiration. They will also handle the electronics involved in power management and servo control, in addition to developing the core open-source software to make the robot move, including ROS support, simple python scripts and physics simulation.
Meet the winner: RoboSavvy Humanoid Design - unl by joshua.chung
Joshua's design has clever double knee joint which may work with AX12 if the position curve of the servos is synchronized and the PID compliance curve is tweaked so the servo doesn't kill itself while transitioning from one position to the next. Or, we could replace the AX12 firmware with custom firmware we have written which allows it to behave as a speed/torque-control servo. It has an unusual foot design. It has no hands. but melisa hands can be added. It has lots of shells and 3D printed parts, so building this will be challenging.
