This paper presents a design of a low-cost, lightweight powerline inspection robot:Robonwire. Though commercial and research robots for inspecting and monitoring powerline are available, the weight of the robot is high and it requires a lot of human effort during set-up and operation. We focus on developing a laboratory scale robot for power line inspection. The robot has three arms and a base frame which houses the electrical and electronic elements to control the locomotion and avoiding obstacles. It uses three powered motors with wheels one for each arm providing the mobility of the robot on the wires. Each arm has two joints. The upper joint connects the arm body to the wheel assembly while the lower one connects the arm body to the base frame. The obstacle avoidance is achieved by lateral rotation of arms in sequence. This paper presents the initial phase of the development in which a robot is built for travelling on wire. The motion planning for obstacle avoidance and simulations for torque requirement analysis of joint motors are also presented.
