They also play "real" instruments, as their Meccano gears drive arms that bow and plonk.
To verify the effectiveness of the proposed algorithms, real experiments were performed for a two DOF SCARA-type direct-drive arm.
A robomech is a multi-input multi-output parallel-drive arm equipped with several end effectors to perform tasks that require the simultaneous execution of coordinated multi functions.

RMSE = SQRT(∑ xi - Xi /n) where xi = driven arm position (or target velocity during sequence training) and Xi = matching arm position (or tracking arm velocity during sequence training).

Driving arms purchases in the continent is Algeria's long-standing rivalry with Morocco and Uganda's involvement in South Sudan's civil war, according to Pieter Wezeman, senior researcher at Sipri.
