Design and DIY for e-stim robot
Design and DIY for e-stim robot By hvprvbo 1. Design of hardware system The hardware system is mainly composed of two parts: the PLC and the button drive module. The user designs the e-stim command list in the computer, and then burn the e-stim command list into the EEPROM in the PLC. The PLC controls the button drive module to realize automatic control of the e-stim device. For PLC chip, the STC15W408AS(STC MCU Limited) is used. We use serial port to communicate with the computer. The e-stim command list is burn into the EEPROM on the PLC chip. When the electro play is started, the PLC reads the command list from the EEPROM and controls the e-stim device via button drive module. The button drive module need to take over the action of hitting the buttons on e-stim device. For a considerable number of e-stim device, this button is a switch. When pressed or released, the corresponding node in the circuit is switched on and off. This behavior is very similar to the on/o
