Robotics Engineer Interview Questions and Answers for Freshers
Q1. how many GPIOs are there in RPI
The Raspberry Pi (RPI) has a varying number of GPIO pins depending on the model.
The original Raspberry Pi Model A and B have 26 GPIO pins.
The newer Raspberry Pi Model B+ and later models have 40 GPIO pins.
Some Raspberry Pi models also have additional GPIO pins dedicated to specific functions like I2C or SPI.
GPIO pins can be used to connect and control external devices such as sensors, motors, and LEDs.
Q2. what are ros topics and nodes
ROS topics are communication channels for exchanging data between nodes in a Robotics system.
ROS topics are named buses where nodes can publish or subscribe to messages.
Nodes can publish data to a topic, and other nodes can subscribe to that topic to receive the data.
Topics enable asynchronous communication between nodes in a distributed system.
Topics can be used to transmit sensor data, control commands, or any other information in a Robotics system.
Examples of topics in ROS...read more
Q3. what are the DH parameters
DH parameters are a set of four parameters used to describe the kinematics of a robotic manipulator.
DH parameters define the geometry and motion of each joint in a robot
They include parameters such as link lengths, joint angles, and link offsets
DH parameters are commonly used in robotics to model and control robot manipulators
They are used to calculate the transformation matrices between adjacent links in a robot arm
Q4. PointCloud2 msg type in ros
PointCloud2 is a message type in ROS for representing 3D point cloud data.
PointCloud2 is used to store and transmit large amounts of 3D point cloud data.
It is a flexible and efficient way to represent point cloud data in ROS.
PointCloud2 messages consist of a header and a data field, which contains the actual point cloud data.
The data field is organized as a binary blob, allowing for different data types and structures to be used.
PointCloud2 messages can be visualized using to...read more
