Neutron

Neutron is a heavyweight robot owned by Team Nebula, which attempted to enter Series 9 of Robot Wars, but was not selected to compete. It was a rebranded version of Tanto, originally built by Team Danby and loaned to Team Immersion to compete in the pilot episode of Series 8.

Design
Neutron is a highly compact robot, driven by two large wheels, exposed at each side, which allow Neutron to run inverted. Neutron features two pronged wedges, to lead robots into its primary weapon, a 300mm diameter, 25mm thick HARDOX disc, spinning vertically with a single tooth. The robot's small size allowed it to use thick, dense HARDOX armour, and holes are cut out of its frame to conserve weight. Neutron is remarkably quick at 24mph, although its exposed wheels create a weakness to spinners.

Qualification
Although the Neutron brand had not been developed at this stage, the core robot applied for Series 8 of Robot Wars under the name Tanto, and while it was not selected to compete in the main competition, it fought in the pilot episode, where it lost its group battle to Ka-Pow! and Turbulence. Although Neutron's team members Jack Tweedy and Craig Croucher were present on Team Tanto, the robot was captained by Adam Hamilton, and fellow member of Team Immersion, Matthew Pearman.

As the Tanto name was first used by Team Danby, the original creators of the machine, the newly formed Team Nebula decided to rebrand the robot upon purchasing it from the Danby brothers. After reaching out to the Unofficial Robot Wars Facebook group, asking for suggestions of astronomical names, Neutron was selected as the robot's new identity. Using this new name, Team Nebula applied to compete in Series 9 of Robot Wars with Neutron, but were not selected to compete.

Team Nebula would not attempt to enter Series 10 with Neutron, with Jack Tweedy instead joining Team Danby to compete with Apex, while Craig Croucher allied with Dave Lawrie to apply with Jellyfish and Ice Cream, although this also was not selected to compete.

Series Record

 * NOTE 1: In its prior guise as Tanto, Neutron was built by Team Danby. For their qualification record, see the Team Danby article.
 * NOTE 2: In Tanto's appearance at the Series 8 Pilot, shortly before its rebrand into Neutron, its team was captained by Adam Hamilton, who competed in Series 10 with Vulture.

Outside Robot Wars
Although Neutron has yet to compete at a live event, it has a prior history under its previous identity, Tanto. For more information, see the Tanto article.

Jack Tweedy is primarily a beetleweight competitor, competing with a variety of vertical spinners:
 * Hyperion - A two-wheel driven beetleweight with a broad wedge, and a vertical spinning disc. Inspired by the US competitor Riptoff, and debuted at the 2015 FRA Beetleweight Championships.
 * Noxa - An invertible beetleweight constructed from HDPE, armed with a drum spinner.
 * Ash 2 - A beetleweight armed with a 2mm Grade 5 titanium wedge, and a 20m HARDOX disc, spinning at 8000rpm.
 * Phobos - An invertible beetleweight armed with a horizontal spinning disc, having originally been designed to feature a vertical disc.
 * Tempus - A beetleweight armed with a large disc, spinning vertically. Achieved third place at UWE Bot Brawl 2018.

Aside from his involvement with Dave Lawrie's team, Craig Croucher is the captain of Snappy Robotics. His robots include:
 * Mr Snappy - A four-wheel driven invertible beetleweight built in 2014, armed with a lifter while being designed for pushing.
 * Mr Snappy 2 - An updated version of the same design, using a two-wheel drive, before it was retired in 2016.
 * Snappy - Croucher's currently active rendition of Snappy, which briefly operated with a gripping weapon before returning to a design similar to Mr Snappy.
 * Mr Cat's Mouse House - A two-wheel driven beetleweight, equipped with a plastic bowl, designed to trap robots in a fashion similar to Tentoumushi. Achieved third place at the UWE Bot Brawl 2018.
 * Mini Snappo - A wedge-shaped antweight armed with a flipper.
 * Snappucino - An antweight made from a kit sold by Alex Shakespeare, armed with a lifting panel.
 * Mr Cat's Mouse Flat - An antweight version of Mr Cat's Mouse House, with the same type of weapon.
 * Tactical Nuclear Penguin - A beetleweight armed with a horizontal bar spinner. Originally built by another roboteer, before being donated to Craig Croucher for the intention of destroying it in battle, which occurred in 2016 at Robots Live! in Reading.
 * Snappy Twins - A currently unfinished design for a featherweight, consisting of two equally weighted invertible wedges.

In 2018, Team Nebula qualified for the first season of BattleBots to be aired on the Science Channel and Discovery Channel. Jack Tweedy, alongside new team member Kyle Barton, will compete with Vanquish, a four-wheel driven heavyweight designed for pushing. Craig Croucher is not present on the team, for he applied to compete in the same season with Two-Headed Death Flamingo.
