Shake tables provide a critical tool for simulating earthquake events and testing the response of structures to seismic forces. However, most existing shake tables are either prohibitively expensive or proprietary, limiting their accessibility for educational and research purposes. To bridge this gap, we present Shakebot, a low-cost, open-source shake table designed specifically for engineering research and education.
Key Features of Shakebot
The Shakebot is built using affordable, high-precision components. This approach not only keeps the cost down but also ensures the reliability and accuracy needed for vibration testing. Here are some of the standout features:
- Open-Source Software with ROS: The shake table runs on the Robot Operating System (ROS), allowing for modular software integration and facilitating easy transition from simulation to physical experiments.
- Accessible and User-Friendly: The Shakebot’s low cost and simple setup make it ideal for students, educators, and researchers, especially in low-resource settings.
Specifications:
- Degree of Freedom: Single
- Movement Degree: Horizontal Table
- Dimensions: 290 x 810 mm (excluding control box)
- Payload: 45 kg @ 1 g
- Velocity: 2,000 mm/s
- Stroke: +/-140 mm (380 mm)
- Max. Operating Frequency @ 1kg 10mm: 25 Hz
- Position Precision: 0.08 mm
- Max. acceleration at 5 kg and 2,000 mm/s: 5 g
- Software: Python (supported by Robot Operating System)

Application in Precariously Balanced Rocks (PBR) Research
One of the most exciting applications of the Shakebot is in the study of Precariously Balanced Rocks (PBRs) by CALTECH. PBRs serve as natural markers that indicate the absence of significant seismic activity in an area. With the Shakebot, the researchers validated the simulations through physical testing.
By reusing the control programs developed in ROS, the CALTECH researches ensured that the ground motions used in simulations are identical to those applied in the physical experiments. This consistency was vital for validating the accuracy of the simulation and ensuring reliable results in both virtual and real-world settings.
Why Choose Shakebot?
- Affordable: Built using readily available components, Shakebot offers a high-performance solution at a fraction of the cost of traditional shake tables.
- Open-Source: With ROS-based software, Shakebot allows for extensive customization, making it suitable for a wide range of seismic research applications.
- Versatile: Whether you are testing small-scale structures or conducting PBR studies, Shakebot is a highly flexible tool for both education and research.
