Move in arc with center X () Z () , radius () , start angle () , end angle () , along Y () in () in ms block is a stack block available in Robotic Arm extension for evive and other Arduino boards. The block moves the end-effector in an arc.
Input Parameters
- Circle’s center point on X-axis.
- Circle’s center point on Z-axis.
- The radius of how big you want your circle arm to carry the movement.
- The start angle of the arc.
- The end angle of the arc.
- Radius on the Y-axis.
- Time to complete the circle.

Note: This block is available in both Stage and Upload mode.
Example
In this script, we will make the robotic arm to make a complete an entire circle but breaking in the two arcs i.e. we will move over the robotic arm into two half circles and complete our circle.
- Define PWM pins for the servos connected.
- The arm will continuously make the arc from the start angle to the end angle with a specified radius and time i.e from 90° to 270°. Wait there for two seconds.
- The arm will again make an arc from 90° to 270° thus completing the entire circle.

Note: Before working with the Robotic Arm, we need to calibrate the robotic arm. To calibrate the robotic arm, click here.
