Wearable Soft Robotic Actuator

Fig. 1. Bare Exoskeleton

Fig. 2. Exoskeleton worn on Hand

This slide displays two images showing the soft robotic actuator device - first as a bare exoskeleton structure, and second demonstrating how it is worn on a human hand.

Myo Armband

Fig. 3. Tatarian, K., et al., (2018).

This slide shows the Myo Armband, which is a wearable sensor device used for electromyography (EMG) signal detection.

Difficulties Throughout REU Process

• Myo Armband Unsupported
• Changing the experimental setup
• Air Leak in Index Finger
• Designing wearable Apparatus

Results

Figure 5:

Two Graphs: The top plot, "Human Hand Sensor Array," shows multiple colored lines fluctuating between 1200 and 1400 on the Y-axis over a time period of 0 to 35 on the X-axis. The bottom plot, "Human Hand EMG Trial," displays multiple colored lines ranging from -100 to 100 on the Y-axis over a time period of 0 to 2 multiplied by 10⁴ on the X-axis.

Results

Figure 6:

Titled "Human Hand Sensor Array and Valve Control," this figure consists of four pairs of plots stacked vertically. Each pair has a top plot showing multiple colored lines fluctuating between 1200 and 1400 on the Y-axis, and a bottom plot with a blue line that's either at 0 or 100 on the Y-axis. The X-axis for all eight plots is labeled from 5 to 6.5.

Results

Figure 7:

This figure presents a table and a matrix. The table, "Table 1. Average Neural Network Accuracy," has four columns: "Human," "No Human 1," "No Human 2," and "Surface." It contains data for ten trials and rows for "Average" and "Std. Dev." The matrix, "Test Confusion Matrix," is a 10x10 grid with rows labeled "Output Class" and columns labeled "Target Class." The cells contain numbers and percentages, with some cells highlighted in green.
