Most vendors in motion controls create motor control boxes that only control their motors.
For user input, they may not have any physical controls or just buttons. The majority of control comes from proprietary apps. Their controllers have limited resources and capabilities inside them as they rely on the processing power of phones and tablets.
The SA2.6 is a powerful motion control computer, handling processing and input/output to a number of resources in real-time and with almost no latency. Under the hood, we have 4 microprocessors and two motion coprocessors that split duties to accomplish the tough task of coordinating many disparate systems and juggling inputs and outputs.
