Robotics, Automaton and Automation Design Solar Mars Bot Energy Storage Robot by Shenzhen Hello Tech Energy Co.,Ltd Solar Mars Bot is a mobile energy storage robot that combines solar power generation, battery storage and charging in one unit. Six photovoltaic panels on the top are moved by connecting rod motors, and a light tracking sensor finds the best angle to the sun. The energy storage module uses lithium iron phosphate cells for a long cycle life. Laser radar and a camera module allow the robot to avoid obstacles outdoors and to plan a route to the user. Charging is started automatically when the stored power is low.
