Open Platform Humanoid Project

ROBOTIS OP2 is an affordable, miniature-humanoid-robot platform with advanced computational power, sophisticated sensors, high payload capacity, and dynamic motion ability to enable many exciting research, education and outreach activities.
“ROBOTIS OP2” is a new version of “ROBOTIS OP” that was formerly known as “DARwIn-OP”.

Visual differences with ROBOTIS OP

The only difference is the mini HDMI port connector from ROBOTIS OP2. Also, the location of the ports differ from ROBOTIS OP2 with respect to ROBOTIS OP. The Mode, Start, and Reset buttons remain unchanged. ROBOTIS OP2 lacks the 3.5cm microphone and audio jacks. In practice these were not implemented with ROBOTIS OP so the loss of these ports from ROBOTIS OP2 will not affect robot operations.

Advantages of ROBOTIS OP2 compared to ROBOTIS OP

As stated above the changes come in the form of an updated PC. The advantages of the new PC are listed as follows:
▪ user-replaceable SSD
▪ user-replaceable RAM
▪ increased compute power (obviously)
