The RoboMower is a line of robotic lawn mowers manufactured by Friendly Robotics. They run off a 24-volt rechargeable battery pack and use three mulching blades. A perimeter switch powers a loop of wire placed around the yard to provide a boundary for the mower.
Operating manuals for the current models are available on the Friendly Robotics web site. Although the manufacturer does not supply repair information to the general public, we have Troubleshooting and Repair pages with information collected, created, or discovered by RoboMower users.
Here are some photos and notes to take apart a RoboMower.

What is a Woot Mower?
Woot! is an Internet commerce company based in the Dallas suburb of Carrollton, Texas, which operates a website of the same name. Founded by electronics wholesaler Matt Rutledge, the site debuted on July 12, 2004, with a unique business model, offering a single discounted product per day, instead of the wide range of choices available through traditional online retailers such as Amazon.com. This model was evolved from Synapse Micro where products are sold to the wholesale computer dealer market. Woot’s novel, irreverent approach quickly attracted a robust community of customers, who share their opinions on the site’s community forums. Product selections tend to emphasize (but are not limited to) computer components and electronic gadgetry, all sold at closeout prices.
The Friendly Robotics RL500 Robomower was the first product sold at Woot.com when it launched on July 12, 2004 and was sold several other times over the next couple years. It was last offered for sale on February 25, 2005. It usually was offered for either $179.99 or $219.99, plus $5 S&H, making it an incredible deal. A typical description as posted on their site can be found here.
- Scientific American magazine, May 2006, pp. 88-89, has an article about how the RoboMower works with some nice translucent diagrams.
- Robot magazine, Spring 2006, pp. 68-70, has an interview with Tyler Ramage from Robo Direct and frequent contributor to the RoboMower Yahoo Groups list. The article has pictures of the mower inside and out, information about how it works, and some of the history of the product. (The listing in the table of contents is very small and easy to overlook.)
