1. The resistor with small resistance value and the resistor with high power in the circuit board are easy to be damaged

The resistor with a small resistance value in the circuit board is often used to limit the current on the power supply line, that is, to act as a fuse, and if the current is too large, it will first blow it off. In addition, many ground capacitors are used on the power supply line to filter, and the size and capacity are generally large, and if the voltage or current is unstable, the capacitor will break down and cause leakage.

2. Fault characteristics and repair of capacitor damage in KUKA robot circuit board

Faults caused by capacitor damage in circuit boards are common in electronic industrial robots, especially electrolytic capacitor damage***. Capacitor damage is manifested as: 1. Capacity decreases, 2. Capacity is completely lost, 3. Current leakage, 4. Short circuit.

3. Determine the quality of the operational amplifier in the circuit board

Understand the above points, so that you can judge the quality of the op amp without using the substitution method or removing the chip on the circuit board.

Obstacle avoidance control of the manipulator – KUKA robots Obstacle avoidance control of the manipulator – KUKA robots

The kinematic redundancy of freedom of the manipulator means that the manipulator has more degrees of freedom than is required at the end of the manipulator. Kinematic manipulators with redundant degrees of freedom have better functions than manipulators with non-redundant degrees of freedom. For example, a manipulator with non-redundant degrees of freedom has obstacles in the external environment.
