A ROBOTIS vice president presents the DARwIn-OP humanoid robot’s control system, hardware, software, and setup.
DARwIn-OP uses a main computer for high-level control and a CM-730 subcontroller for communications and real-time sensor handling. The CM-730 gathers data from devices such as the gyroscope, buttons, LEDs, and servos, then relays it to the main computer over a 1 Mbps RS-485 link.
The main computer runs an Intel processor at about 1.6 GHz, with 1 GB of memory and an SSD; memory can be expanded to 4 GB. It offers HDMI, Wi-Fi, USB, and microSD, and ROBOTIS ships the system with Ubuntu while noting that Windows XP or Windows 7 can also be used. The CM-730 uses a 72 MHz ARM Cortex processor and supports TTL and RS-485 communications.
The presentation describes actuator changes, including replacing contact-based potentiometers with magnetic sensors to avoid wear at the contact point. The robot uses a gyroscope, additional motion sensors, and four foot pressure sensors per foot. Its head includes a camera, and the presenter also describes microphones for sound direction and programmable full-color LEDs.
A standard battery provides roughly 20 to 35 minutes of operation, while an optional 2 Ah battery is said to last about 40 to 45 minutes. ROBOTIS offers an Open Darwin SDK in C++ for Linux with GCC, while allowing users to replace the shipped software or work in Windows. The planned tools cover motion editing, device management, and visual monitoring.
The presenter moves into a hands-on exercise and guides attendees through connecting power and using the switch. A later instruction notes that startup or preparation can take over a minute, so users should allow time before proceeding.
