DSSERVO 3225 Servo Compatibility Inquiry

Hi @Athena, I am curious about the compatibility of a 25 kg DSSERVO 3225 digital servo, which operates at 4.8 to 6.8 volts DC, with my EZBv4. Additionally, I'm considering placing a 10F capacitor between the positive and negative wires. Would this assist or interfere with the servo's operation when using the EZBv4? Thank you, Jack

ARC Event Notification Capabilities

Does ARC have the capability to notify me when a specific event occurs, such as sending a text message, an email through Gmail, or a Facebook Messenger notification? For instance, I currently have a script in ARC that runs in a loop every 30 seconds to check its connection to the EZ-Robot EZ-B controllers. It would be beneficial if ARC could notify...

Managing Servo Commands Without TCP Server

How can I manage ports that exceed 23 using ARC @Athena? My ESP module currently supports ports higher than 23 with the integration of two PCA9685 PWM controllers, each controlling a set of servos. All connected ports have servos attached. My aim is to creatively utilize existing ARC skills and script commands to facilitate communication with the...

Troubleshooting Rovers IR Sensor Issue

Hi @Athena, I need some assistance troubleshooting an issue I've encountered with my robot. The setup involves a rover powered by four stepper motors, each controlled by a motor driver board connected to an Arduino Mega 2560. The Arduino handles motor control using PWM, while an EZ-B v4 is tasked with executing scripts to synchronize an IR sensor...

Chinese Robotic Cat Assembly Challenges

Hi everyone, I’m working on a Chinese version of a robotic cat. The unique design of the base and servos requires no screws for assembly. However, the assembly process is quite challenging because you need to hold all parts in your hands to connect them properly. I did cheat a little by using a few screws to help with the assembly! I'm still...
