Application Cases

Experiment Name: Power Amplifier-Driven Dielectric Elastomer Robot

Research Direction: Bionics

Experimental Content:
By applying high voltage to the actuation unit of the robot, observe its motion process within one voltage cycle.

Test Objective:
Utilize dielectric elastomer actuators to fabricate a bio-inspired soft robot capable of running.

Test Equipment:
Signal generator, power amplifier (Aigtek ATA-7030 high-voltage amplifier), dielectric elastomer robot, high-speed motion camera.

Experimental Procedure:

As shown in the figure above, the setup includes a signal generator to produce an excitation signal with a frequency of 3 Hz and a square waveform. The signal is then amplified by the high-voltage amplifier (Aigtek ATA-7030) to 5.5 kV, which powers the robot to induce motion. A high-speed camera captures the robot's movement images.

Experimental Results:

1. Initial powered state of the robot,

2. Rear feet lift, and the body rises,

3. Body reaches maximum upward angle,

4. Power is cut off, initiating a jump,

5. Body becomes airborne,

6. Robot lands.
