Matilda was one of four House Robots to be sold as part of the Robot Wars Construction Sets range, released in August 2019. Based upon the Series 3-4 version of Matilda from Robot Wars, is the most inexpensive of the four construction sets at £19.99 RRP, due to its lower quantity of pieces, at 160.
The Matilda Construction Set was sold as a box containing 160 stainless steel pieces, which the user could assemble using a set of instructions included as a paper sheet in the box. When fully assembled, the toy replicates Matilda as it appeared in Series 3-4 of the show, complete with chainsaw, despite the back of the construction set's packaging reflecting the Series 8 version of Matilda.
The toy runs on two wheels, and was oddly coloured silver, rather than the actual House Robot's purple colour-scheme. Nevertheless, the toy was otherwise an fairly accurate interpretation of the House Robot's design, with a number of holes being added into the metal struts to save weight, permit manual bending, and to make the toy somewhat resemble Meccano.
- Although the Matilda Construction Set enjoyed a quiet launch through online retailers in August 2019, the toy was first revealed as early as March 2018, and was not seen again between the official announcement and release, with Robot Wars offering no marketing on the toy's behalf.
- The Matilda Construction Set was not the first constructible Matilda toy to be released as Robot Wars merchandise, with the Matilda Pitstop Kit releasing first in 2001.
